Morpx MU User Manual

MU User Manual

Introduction

Thank you for purchasing MU by Morpx and join our journey to bring vision and AI to all toys and
educational robots! MU is started from the simple idea of replacing remote controls with a more
natural ways of interaction. Today, with MU, your toys are no longer dummies controlled using
buttons or screens, but robots that can sense the environment and have their own minds of
“playing”, based on a set of rules programmed in their software.

MU is our first milestone in this direction and you are invited to experience what we've created.
To get you started quickly, MU is pre-loaded with models that can detect faces, people
silhouettes, lines, balls, fingers, and many remote-control codes of popular robotic kits. Take a
few minutes to look through this user manual and enjoy your robot building time with MU!

What’s inside a MU package?

① MU robotic head with vision and AI on board.
② Universal mount for MU.
③ Double-sided foam stickers ×2.
④ Micro-USB cable for charging and data transferring.
⑤ OTG plug for data transferring with Android based devices.

Warning

•DO NOT immerse MU or other parts in the water or any kind of liquid.

•DO NOT drop MU as this may damage the camera and the PCB assembly.

•Small parts, not for children under 3 years old.

Battery

•How to charge the battery

MU uses rechargeable Lithium Polymer battery.
To charge it, insert the USB cable to the micro-USB port on the back of MU. Insert the other side
of the cable to a standard USB port.

○ When MU is charging, the

charging light is on.

○ When MU is fully charged, the

charging light will automatically

shut off.

•Battery Safety

1.Battery is a small object.

2.Battery CAN NOT be replaced. DO NOT replace the batteries.

3.DO NOT dispose of batteries in fire, as batteries may explode or leak.

4.Use only the batteries provided by the manufacturer.

5.DO NOT heat, dismantle or deform batteries.

6.DO NOT disassemble or modify, or for any other purpose.

7.DO NOT short-circuit the battery.

8.When the battery is accidentally ballooning or having effluent, or smoke, please stop using MU
immediately and contact Morpx.

9.MU has a battery management chip inside. Please use a computer USB port to charge. Using
mobile phone charger or power bank may cause damage or shorten the life of the battery.

10.DO NOT leave MU under direct sunlight for a long time.

11.If the device is left unused for a long time, the battery might be drained. Please recharge it
before use.

Getting Started

MU works with a robotic body by sending remote control commands. Just imagine a toy having
its remote control on top of its head.. Currently, MU supports the control commands of Lego
Mindstorms EV3, Lego Power Functions, Hexbug Spider, and Hexbug Fire ant.

MU uses infra-red (IR) technology to send control signals, theoretically any infra-red controlled
toy can potentially be controlled by MU. We will add newly supported toys through firmware
updates in our online forum (forum.morpx.com). For advanced users, MU also has ports to
connect directly with servos, Arduino, or Raspberry Pi (Please also check our online forum for
details).

To mount MU on a toy, use the included double-sided tape. First, secure the mount on the toy.
(P1)
Then insert MU onto the mount. Make sure that the camera direction is looking forward. (P2)
Press the Power button to turn on MU. (P3)

NOTE: The effective range of the IR signal of MU is limited to avoid interferences with other
devices. The typical range is a few inches under or behind the device. P4 illustrates the effective
range. Please make sure your toy’s IR receiver is within the covered range.

Mode Button

For a MU to work on a toy robot, it has to

know what the toy is and what target object is

selected for MU to detect. These two pieces of

information are selected using the mode

button at the back of MU. Long press the

mode button will switch among the supported

toy mode. MU will give voice confirmation of

each toy mode after the long press.

For each toy type, there may be different

target modes that MU will search and track.

Short press the mode button to switch among

these target modes. Again, MU will give voice

confirmation of what the current target mode

is.

demo mode that detects
faces and gives welcome

Vision Sensor Mode

loop mode/setup mode

For arduino/raspberry pi
developer, detection results
sent through UART serial
port, please check our forum
for more details.

The general behavior of the pre-programmed MU is searching, detecting and following.
When MU detects a target object, it will play a sound and drive the toy to follow it. Otherwise
MU will drive the toy around to find the target. Note that If multiple target objects appear, MU
might switch between the targets.
You should adjust the mount direction when the target mode is changed to make it easier for
MU to spot the target.
NOTE: The viewing angle of MU is about 40° horizontally in front of the camera. MU might not
respond to a target If the distance between them is more than 1 meter. MU also works better in
good lighting conditions and might have trouble finding object in low light situations.

Please vision www.morpx.com to get more details about the different modes of MU. We have
some videos that show you how to play with MU in each mode.

Q

＆

A

Q: My MU cannot be turned on.

A: Charge MU to make sure its battery is full. If it still does not work, reset MU and try to turn it
on again. To reset MU, insert a thin needle tip to the reset whole on the bottom of MU until you
hear a button click sound

Q: My MU cannot respond to a target object.

A: Make sure the camera is facing forward, and possibly adjust the angle of the mount. Try to
give it an easy target object to follow.. Make sure MU is working in the right toy mode and target
mode. Also, make sure both MU and the toy is fully charged.

Q: When I charge the battery, the charging light is blinking

A: This might be due to a battery error. Try to detach and plug in the Micro-USB cable again. If
this does not work, contact [email protected] for help.

If you have other questions, please post it on forum.morpx.com. Someone in the MU team will
reply to the posts. Alternatively, you can
