Information about limited warranty and responsibility

The warranty granted by AREXX Engineering is limited to the replacement or repair of the
Module and its accessories within the legal warranty period if the default has arisen from
production errors such as mechanical damage or missing or wrong assembly of electronic
components except for all components that are connected via plugs/sockets.
The warranty does not apply directly or indirectly to damages due to the use of the robot.
This excludes claims that fall under the legal prescription of product responsibility.

The warranty does not apply in case of irreversible changes (such as soldering of other
components, drilling of holes, etc.) of the module or its accessories or if the module is
damaged due to the disrespect of this manual!

It cannot be guaranteed that the supplied software will satisfy individual expectations or
will run completely error-free and without any interruption. Moreover the software can be
freely changed and is loaded into the unit by the user. Therefore the user carries the full
risk regarding the quality and performance of the unit including all software.
AREXX Engineering guarantees the functionality of the supplied application examples
provided the respect of the conditions specified in the data sheet. If the SAM-04-LAN or the
PC software turns out to be faulty or insufficient, the customer carries all costs for service,
repair or correction.
Please note the relevant license agreements on the CD-ROM!

The exclamation mark attracts the attention of the user to important
instructions that must be adhered to. If you make a mistake in this part, it
can lead eventually to the destruction of the robot or its accessories and
even endanger your health or that of your environment!

The "Information" symbol draws the attention to useful tips and tricks or
background information. It is not always essential to understand
everything but it is often very useful.

Safety recommendations

IMPORTANT:

Prior to using this robot arm for the first time, please read this manual thoroughly up to
the end! They explain the correct use and inform you about potential dangers! Moreover

they contain important information that might not be obvious for all users.

- Check the polarity of the batteries or power supply.

- Keep all products dry, when the product gets wet remove the power directly.

- Remove the batteries or power when you are not using the product for a longer period.

- Before taking the module into operation, always check it and its cables for damage.

- If you have reason to believe that the device can no longer be operated safely,

disconnect it immediately and make sure it is not unintentionally operated.

- Do not operate the module in rooms or under unfavourable conditions.

- This module is equipped with highly sensitive components. Electronic components are
very sensitive to static electricity discharge. Only touch the module by the edges and
avoid direct contact with the components on the circuit board.

Normal use

This module is developed to use with robots, which allows you to determine basic behaviour patterns and

reactions of the robot to external influences yourself.

The module was developed as an experimental platform for all electronic technicians with interest in robotics.

In practical tests, it visualises the influence and effects of software parameters as well as physical parameters

via the corresponding sensor technology. Any use other than that described above is not permitted.

The product is not a toy and should be kept out of reach of children under 14 years of age! It may only be used

in closed, dry indoor rooms. The product must not get damp or wet. Use other than that described above can

lead to damage to the product and may involve additional risks such as short circuits, fire, electrical shocks etc.

RP6 Gyro Module (Yaw)

Introduction

The Gyro module converts rotations around the yaw axis and converts it to an analog
output signal. This allows you e.g. to detect that the robot is turning into the
commanded direction. Slippage can be measured depending on the software
implemented on the motion controller.

1.) Technical data:
VDD = 5.0 V +/- 5%
Vout = Vout(0) + 10mV / dps +/- 2%
Vout(0) = 2,5 V +/- 2% (no motion)
Range = approx.. 200dps max

2.) Pin out:

Pin 1 (K2)

Pin 1 (K1)

PIN1 K2 = VDD PIN1 K1 = SLEEP/PD
PIN2 K2 = n/c PIN2 K1 = ST
PIN3 K2 = GND PIN3 K1 = n/c
PIN4 K2 = OUT PIN4 K1 = n/c

3.) Connecting to RP6WIFI or RP6 Robot.

Connect PIN1/K2 of the module to VDD (5.0V) and PIN3/K2 to GND - watch out
reverse polarity! Choose a free ADC input of your RP6 Robot or WIFI board and
connect it to PIN4/K2 OUT which provides the signal. In addition you need to control
the PIN1/K1 SLEEP/PD and PIN2/K2 ST to enable the operation of the module.
