1. PRODUCT DESCRIPTION WIRELESS

1.1. Introduction

The „Wireless“ transmission module from AREXX is an extension
set for the ASURO robot that is also suitable for other robot models
such as the AREXX Arduino (AAR) or the PRO-BOT from Conrad. The
„Wireless“ transmission module contains the circuits for standar­dized infrared communication so that you can continue to use the
ASURO USB-IR transceiver with the ASURO Flash software.

Moreover this extension module offers space for an APC220 or a
Bluetooth module. Both modules are bases on radio transmission.
The main advantage of radio transmission is the fact that ASURO
doesn’t need any visual contact with the control unit, the control
range is bigger and the robot is easier to control e.g. via an android
mobile phone.

The „Wireless“ transmission module is supplied fully mounted. Only
the contact pins need to be soldered. Almost all components are
pre-soldered so that you need no extra time for the soldering.
The challenge of the set lies in the programming of the control
software. Programming tutorials are available on the website. The
control can be done via a PC or an android mobile phone.
Visual Basic offers a programming environment for the transmission
application on the PC. The example application is user-adjustable.
You can connect to the Bluetooth module via a mobile phone so that
the system can send data both ways. This communication takes
place in an android environment that is quickly developing towards a
control system for mobile radio transmission. The ASURO extension
set, this manual and the available software offer you the opportunity
to get acquainted with Android.

Enjoy your extension set the its RF modules!

2. Bluetooth

2.1 History

The Bluetooth technology was developed by the company Ericsson.
Bluetooth is an open standard for wireless transmission between
units over short distances. Just imagine mobile radio units with a
wireless headphone connection or data transfer between mobile ra­dio units or a GPS receiver that sends wirelessly data to a
telephone.

In 1994, Ericsson developped Bluetooth as a wireless way of com­munication between mobile radio units and other systems.
Jaap Haarsen who worked at that time for Ericsson, developed the
most important technical part. The name Bluetooth comes from the
king of the vikings Harald Bluetooth. Initially, Bluetooth was the
name of the project and as no better alternative had been found,
this name has been kept for the end product.
The communication system spreads very quickly and after a short
time, the biggest electronic companies come together to set up the
‘Bluetooth Special Interest Group’ (SIG).
A worldwide application needs to be made available worldwide.
Therefore a universally applicable frequency has been searched and

found in the 2,45GHz frequency range.

2.2 Technology

Bluetooth is a radio transmission of speech and data over short
distances. The selected communication structure is a point to multi­point link which means that one transmitter can transmit to several
receivers. As soon as two Bluetooth units start communicating, a
so-called „piconet“ is set up. Several pico networks make a scatter
network.

- 5 -

Within a pico network Bluetooth supports a maximum of 8 active

units whereas 127 units can operate a communication link that is
temporarily kept in a passive state (parked) (g. 1).

Fig. 1 : Scatternet

The energy consumption of Bluetooth is extremely low: 30 micro­amps in passive standby mode and 8 to 30 milli amps in active
state. This low consumption allows Bluetooth to be used also in
battery powered mobile units.

Bluetooth systems are divided in 3 different categories:

Category 1: Projects for long distances (up to 100m)
Category 2: For standard distances (up to 10m)
Category 3: For short distances (10cm to 1m)

- 6 -

3. Android

3.1 Background information

Android is an „open source“ platform for mobile units such as
Smartphones and Tablets that have been developed by the company

Android Inc.. In 2005, Android has been taken over by the company

Google.

The unveiling of the Android distribution in 2007 was announced
with the founding of the Open Handset Alliance, a consortium of 40

hardware, software, and telecommunication companies devoted to
advancing open standards for mobile devices .

Android is based on a Linux kernel and the Java program environ-

ment.The SDK development tool (Software Development Kit) allows

not only Google but also other developers to create applications.
They can subsequently offer these applications to the android
market. On this market, end users can search and install

applications. Here you can nd also all information about the

applications. The distribution of applications whether they are free of
charge or charged, is promoted. The developers are allowed to offer
these applications also outside the android market.

The applications are developed for a specic android version.

However they are retrocompatible. That means that an application
that has been developed for android 2.2 can also be run under 2.3.

The versions published so far are listed in the g. 2 table.

The number of users per version is indicated in g. 3 below

the table.

3.2 The Software Development Kit (SDK)

Google unveiled the SDK software so that users are able to write their
own applications for a smartphone, a tablet PC or both. The SDK con-

tains a collection of various helpful tools such as a debugger tool and
an emulator plus a series of example applications and tutorials on the
website.

Open following link to download the SDK:

http://developer.Android.com/sdk

On this page you will nd the installation les and extensive instructi­ons on how to install the SDK.

3.3 Eclipse

Eclipse is an open source framework of the Eclipse Foundation, a non-

prot association for software development environment. The most

popular application is the development environment for the Java pro­gramming language.

The SDK contains an Eclipse plug-in that enables a programmer to

easily start, compile, debug and emulate an android project.
The Eclipse programme is an open source software and can be down­loaded on following

http://www.eclipse.org/downloads/

3.4 Hello World

The „Hello World“ programming instructions explain how easy it is
to transfer the text „Hello World“ in an application to a terminal. The
instructions explain step by step how you have to start a project up to
the very last step, how you represent the „Hello World“ in the emula­tor.

The website of the tutorial is:

4. The Wireless control set from AREXX

The „Wireless“ control set allows you to install an APC220 module
or a Bluetooth module on ASURO or other robots. Thus you can
communicate with the ASURO not only via Infrared but also via RF
frequencies. The advantage of the high frequencies is that transmitter
and receiver don’t need visual contact any more.

ASURO can communicate with the PC if an APC220 is installed on the

Wireless radio set. You will nd further information on this subject in

chapter ‘APC220’. The Bluetooth module allows you to communicate

with the PC and an android smartphone. You will nd further

information in chapter ‘Bluetooth Module’.

4.1 Specications

The AREXX „Wireless“ control set includes:

• IR-receiver or transmitter for the Flash transmission to ASURO

• Socket for the APC220 or Bluetooth RF module

• Switch for the IR or RF transmission

• Experience board to build an additional circuit

• Connection options for free gates of ASURO

Following gures show the layout of the PCB. The free

experimentation area for the additional circuit is clearly visible.
There will be even some space left below the APC220 because it is
installed in some distance to the PCB.

Please note!

Fig. 4 : Wireless extension kit

The switch on the PCB allows 2
positions: (1) Infrared connection
or (2) Bluetooth / APC220 commu­nication.

If you want to transfer the software
via Flash into ASURO or if you wish
to communicate via Infrared, this
switch must be set to ‘IR’.

If you want to communicate via
Bluetooth or APC220, the switch
must be set to the other position.

- 10 -

4.2 Installation on the ASURO robot

The installation of the „Wireless“ radio modules can be explained in 3
steps:

Step 1.

First of all the ASURO PCB must be prepared as follows for the instal­lation of the „Wireless“ radio module:

1. Unsolder the components at the locations marked in red and

remove them from the PCB (g. 9). Use a specic soldering iron or

special unsoldering tin to unsolder the components.

Caution:
Make sure not to damage the solder lugs because you
will need them later for the re-soldering.

Abb. 5 : Lötachen

B.2. Solder the supplied socket parts on these connection areas.

Install the 1x3 socket on the connectors featuring three adjacent
areas. The shape of the area is not important. Now you can solder
the remaining 1x2 sockets on the free connection areas

- 11 -

Step 2.

Install now the ASURO extension set on the ASURO PCB. The set

should t accurately into the previously installed socket parts.

Fig. 6 : ASURO with radio control PCB (Side view)

Fig. 7 : ASURO with radio control PCB (Front view)

- 12 -

Step 3.

Install now either the APC220 or the Bluetooth module.

Fig. 8 : ASURO with Bluetooth

Fig. 9 : ASURO with APC-220

The installation of the hardware is nished. Now you can establish a

connection with the various applications.

In chapter ‘APC220’ we explain how you can control ASURO via the
APC220 module.

The chapter ‘Bluetooth module’ explains how the Bluetooth commu­nication will work.

- 13 -

5. APC220/Bluetooth with PC radio data communication

In order to install a communication link between the PC and Asuro we
need a dongle. We decided to use the RP6v2 Programmer adapter

(WT Dongle).

Fig. 10 : RP6v2 USB Programmer
(WT dongle)

For wireless communication from the PC we prefer the APC220 radio
data module or a Master Bluetooth module. These modules are modest
in energy consumption and easy to install, which are convincing de­tails in choosing the components for robotic designs.

5.1 Setup for the wireless PC-communication link

Frequency and baud-rate for the APC220-modules will be setup at
standard values with the help of the WT-dongle. For this purpose a
special software for the WT-dongle has been written in Visual Basic
(VB), which provides us with an easy setup. This software may be
found in the APC-220 application’s software.

Connect the WT-dongle with the PC by USB-cable. Additionally the
RP6v2 programmer adapter requires the installation of a driver soft­ware. The most recent driver will be found at the RP-robot’s section in
our website.

The APC220- respectively Bluetooth-module is to be inserted at the
WT-dongle. Use the Visual Basic program APC-220 application to setup
the APC-220 and to control the robot.

5.2 Preparation for the wireless communication

Important!

The robot cannot communicate through a wireless connection yet.

Besides the hardware modication, when the wireless extension PCB

is mounted on the robot, a program must be loaded.

1 2

PC or Phone

TRANCEIVER 1

In case of Android communication, an application should be loaded
in an Android Smartphone or tablet. In case of PC communication,

transceiver 1 is placed on RP6v2 USB Program Adapter (WT dongle)

and the application must be installed on the PC.

TRANCEIVER 2

First the extension set must be installed with the RF module
APC-220 or Bluetooth. Finally, the correct software has to be loaded
in the robot.

The software depends on the robot type:

*.HEX (Hex le) for:

- ASURO

- RP6(v2)

- ROBOT ARM

*.PDE (Arduino le) for:

- AAR of andere Arduino robots

Robot

*.CBAS (C-Control le) for:

- PRO-BOT128

- 15 -

6. APC220

In combination with the APC220 module, ASURO can be controlled
via the „ASURO control“ programme that needs to be installed on
the PC. “ASURO Control” can be downloaded from the website. The
software has been written in Visual Basic and is available to the user
as a variable source.

The ASURO software needs to be slightly adjusted. This software is
also an open source product.

The adjustment is necessary because the system has to transfer a
protocole that includes a control byte and a set of information bits.

Fig. 12 shows how the application (in orange) transmits the signal

for the data request at the PC. The ASURO system replies with the
reply data in red.

Protocole from ASURO to PC:

Fig. 12 : Communications exaomple

The ASURO software contains some functions to send requests to
the sensors and to control the motors. If the control programme
sends a request, ASURO transmits immediately the data to the

client. At this stage you have the option to add 4 more information

bytes to the signal. This could e.g. be a thermometer that is
connected to the free connectors of the extension set.

The following text describes the code for the data transfer of this
kind of measurement data.

- 16 -

This code shows that the system calls a few functions in Battery ()
e.g. in order to measure the battery voltage. This function supplies a

value between 0 and 255 that is processed in the PC programme and
displayed on the terminal. The bytes 10 to 13 are free and can be

freely programmed.

Fig. 13 : Asuro Control Software (Visual Basic)

Once the application ‘ASURO CONTROL’ has been started, the pro­gramme displays the screen above. Now you can get in contact with

ASURO and control the robot. The WT dongle must be connected to the
PC. When the WT dongle is connected, a click on the ‘Refresh’ function
triggers a request to all connected COM ports.

Once you have selected the correct COM port for the WT dongle, the
connection will be established by clicking on the ‘Connect’ function on
the ASURO control screen. This command triggers the link between the
WT dongle and the ‘ASURO Control’.

Consequently the motor speed and the battery voltage will be display­ed in the bottom right corner of the screen. As soon as a switch on the
front panel of the robot is activated, the programme marks this switch
as a red dot. This way the programme shows a collision on the ‘ASURO
Control’ display. The programme display of the application shows also

the colour change of the ASURO LEDs.

- 17 -

The ASURO robot can be controlled via buttons on the right side.
The speed is set via a slider on the upper right side. Moreover is it
possible to control the robot via a keyboard. To this end, you need

to tick on the field ‘Key Control’.

W: Forwards
A: Left
S: Backwards

D: Right

E: Stop

There are several ways to set the operating frequency of the
APC220. If several APC220’s are operating close to each other,
the protocole will make sure that the data will be sent to the right
ASURO.

However, it is recommended to avoid this kind of situation and if
possible, choose different transmission frequencies as some pro­grammes communicate several times per second with ASURO.

The APC220 operating parameters are set in the PC programme and
can be adjusted. Click on ‘Settings’ in the main dialogue page of the

programme so that following contents are displayed (fig. 14) :

Fig. 14 : Settings in
Control Programm

- 18 -

7. The Bluetooth Module

You can control ASURO via a PC or a telephone if you install a Blue­tooth Slave module inside the extension module. To do that, you
need to install a Bluetooth Master module on the WT dongle. The
difference between the Slave and the Master module is shown in

g. 15 and 16.

Afb. 15 : Slave

Afb. 16 : Master

Those Bluetooth modules are only available in the ARX-WRL03 KIT

The master module (right-hand side) is marked with a white dot on
the upper IC. Moreover the module features a switch.

The slave module (left-hand side) has no white dot and no switch.

Once both modules are switched on, the Master will look for a Slave
and establish automatically a connection. Once the connection has
been established, the Master will save the slave address.
If the connection is interrupted and the Master will be looking for its
slave again at a later stage, the system will only look for the Slave
whose address has been saved.

- 19 -

This situation is shown by the blue LED. In this procedure following
operating modes are dened:

Fast ashing: Slave and Master are not connected together

Steady on: Slave and Master connected together

Slowly ashing: The Master is not connected but it has saved a
slave address. In this case you can erase the
saved address by pressing the switch.

You can chose a name for the
Bluetooth Slave module. In order
to let the system communicate
with another Bluetooth unit, the
adjustment of the baud rate and

the PIN code has been installed as

an option.

You can change these parameters
in the ‘settings’ menu on the main
page. Click on ‘settings’ in
the software to display following
contents.

Fig. 17 : Bluetooth Settings

The module that you want ot adjust must be in the WT dongle when
you make the changes. The changes will saved by clicking on the item
‘save settings’.

The Log protocole shows if the saving process was successful. If this
is not the case, a so-called ‘time-out’ is announced.

Please note:

The name of the Master module cannot be changed. Once you have
saved the baud rate and the PIN code, a time-out is announced. This
is normal.

- 20 -

Once the Bluetooth Master module has been installed in the WT
dongle or the Slave in the ASURO extension kit, a communication
link can be established with ASURO exactly as for the APC220.

Start the ‘ASURO Control’ programme. The COM port remains the
same and the same steps as described in the APC220 chapter are
executed.

- 21 -

8. Android mobile phone application

If you want to control ASURO via a mobile phone, you need to install
the Bluetooth Slave module on the ASURO extension kit.

After that, you have to install the ‘ASURO Bluetooth’ application on
your mobile phone. This software is available on the AREXX website.
In the same area you can download the source code for this
application so that you can input the source and match it to your
own needs.

Most android mobile phones are tted now with the operating

system Android. Therefore this application has been written for

Android 2.1 or Android 2.1 or higher.

Fig. 18 : ANDROID APP

After the start of the application, the programme is asking for per­mission to start Bluetooth if this hasn’t happened yet. The interface
is very clear.

- 22 -

As soon as you click on the ‘options’ key of the unit, the programme
opens a window with the message ‘Connect a device’ and

‘Disconnect’.

These commands are self-explanatory: rst of all, the telephone has

to establish a connection with the Slave module.

With the command ‘Connect a device’ you are asking the telephone
to search for Bluetooth units nearby. As soon as the name of a Slave
module appears, you can click on the name and the system will es­tablish the connection.

Once the link has been set up, you can control ASURO via the appli­cation.

- 23 -

7. Background Information

7.1 APC220

Communication between the PC and Asuro may be accomplished by
a APC220 radio data module, which is a transceiver from Appcon
Technologies.

A transceiver is a combination of a transmitter and a receiver in a
single chip, which allows us to transmit and receive signals by using
only one singular device.

The transceiver has been equipped with a UART-interface, which
enables the module to communicate with a PC or a micro-controller.

Fig. 19 : APC-220

Fig. 20 : RF Communication

The module’s energy consumption is low (+/- 30mA) and installation
is rather simple. These features are the basic reasons to choose the
module for wireless communictions.

The communication range at a baud-rate of 9600 bps is specied at
a maximum of 250m and at 1200 bps at 1200 meters. These speci­cations may be found in the data-sheet.

In a previous project (Wild Thumper) the same APC220-module has
been implemented and extensively tested. In these tests a 200m-

range for reliable communications has been conrmed.

The disadvantage for this receiver is the missing proprietary protocol

for transmitting data. Therefore we will have to dene this protocol

for transmitting data.

- 24 -

7.2 Bluetooth

Bluetooth is an open standard for exchanging data between sys­tems over short distances and has been developed by Ericsson as
an RF-communication link between mobile phones and other equip-

ment. Communication uses the 2,45 Ghz-band and does not require

a line-of-sight connection. The high GHz-frequency band allows
Bluetooth-signals to penetrate and pass concrete materials as long
as they do not contain metals.

Bluetooth-systems may be considered as alternatives for cable­connections and is used to interconnect all sorts of equipments. The
developers concentrated on cheap radio-technology, which enables
us to integrate Bluetooth in any electronic design.

Bluetooth’s low energy consumption (30 micro-amperes in ‘hold
mode’, respectively 8-30 mA during active communication phases)
allows us to use the system in mobile equipment which depend on
battery power supplies. Standard Bluetooth-systems (class 2)

ranges up to 10 meters.

Modern mobile phones usually have been provided with Bluetooth­modules, which is a good reason for us to install Asuro- and other
AREXX-robots with Bluetooth

- 25 -

8. Visual Basic

An application will be needed to use a PC to control the Asuro robot.
A great variety of programming languages is available for such
applications.

Initially normal students will not be experienced in developing appli­cations. Therefore we decided to choose Visual Basic, which provides
an easy way to develop applications.

Visual Basic (VB) is a programming language and a development
tool, allowing is to create software for the Windows operating sy­stem. The attribute “Visual” refers to the Graphical User Interface
GUI) and the attribute “Basic” refers to the programming language
BASIC (Beginners All-Purpose Symbolic Instruction Code).

The project had been set up to work with Visual Basic 2010, which is

the most recent version available today.

Fig. 21: ISP connector

- 26 -

Fig. 21 illustrates the main program’s window. In the left box we

may identify the area to insert buttons, timers and text-boxes. As
a user you might adapt attributes for these elements’ and refer to
these elements in your programming code.

If you press the ‘refresh’ - button at the window the button’s driver
software will be activated.

Private Sub Button_Refresh_Click
(ByVal sender As System.
Object, ByVal e As System.EventArgs)
Handles Button_Refresh.Click

GetSerialPortNames()

End Sub

On activating the ‘refresh’ - button the above sample code will call

the function ‘GetSerialPortNames()’.

- 27 -

8.1 Software Development Kit

In order to enable users to write their own applications for
smart-phones, tablets or both Google released a Software

Development Kit (SDK). This SDK provides us with a number of

sophisticated tools, such as a debugger and an emulator.
The relevant website also contains a great number of sample
applications and tutorials.

The SDK Manager (gure 22) allows the user to add platforms to

his development workspace. He may also choose to install various
sample applications.

Fig. 22 : SDK Manager

- 28 -

The SDK also provides us with a Virtual Device Manager (gure 23).
This Android Virtual Device Manager enables the user to dene a

virtual device, which allows the designer to emulate and debug his
newly created software.

Fig. 23 : Vritual device manager

You may download the SDK from the following website:

http://developer.android.com/sdk

This site provides us with the installation package including detailed

instructions for the SDK’s installation procedure.

- 29 -

7.5 Eclipse

Eclipse is an open-source software framework, designed by the
Eclipse Foundation for software development purposes. The most
popular application is a development environment for the program­ming language Java.

The SDK has been equipped with an Eclipse plugin, which enables a

software developer to easily start an Android project, including com­piling, debugging and emulating the software.

At completion the designer will create an .apk-le for the

application’s installation, which may be transferred to any Android
telephone.
