Q1.What is MU SpaceBot?

A:MU SpaceBot is an AI enabled wooden building kit, an ideal STEAM toy for home and school use. Please check the product page ( for detailed information.

Q2.What is the recommended age for MU SpaceBot?

A:We recommend 8 years old and up.

Q3.How long does it take to assemble a SpaceBot?

A:It usually takes about 1.5 ~ 2 hours. Young kids might need the help of an adult.

A:Yes. Please visit for instructions.

Q5.I can not program my SpaceBot with my iPhone?

A:If you bought the Android version of MU SpaceBot, you only can program it on PC or android phone. If you bought a Bluetooth version, you can use our MU Bot app or program it on PC(

Q6.My SpaceBot does not have the music mode. Why?

A:Please use the mode button on top of the SpaceBot to switch to Music Mode, and make sure your SpaceBot was placed on the rectangle area of the paper keyboard. Sometimes it might take some time for the SpaceBot to find the keyboard. When you hear “Let’s play”, you will be able to use the keyboard to play music.

Q7.I can not record my voice in PC programming. Why?

A:Currently the voice module only works in Chrome.

Q8.My SpaceBot was bought a long time ago, and the MU Bot app didn’t work on the SpaceBot. How can I update the firmware?

A:Please check for the latest firmware.

Q9.Can the SpaceBot walk?

A:No. The SpaceBot can move its head. But when it lies down, you can program it and make its body move. It can be a fun way to play with your SpaceBot.

Q10.How can I find the SN for my MU SpaceBot?

A:The SN can be found on the MU PCB Board in the SpaceBot kit.

Q11.Connect USB version of SpaceBot with MU Bot App(android)

There are some Advanced Actions may not be supported by your SpaceBot when you are programing,you should update your SpaceBot firmware by

A:USB version of SpaceBot
1. Open the USB connection page of APP
2. Open SpaceBot and make sure SpaceBot is in programming mode
3. The USB is connected to the SpaceBot, and the frame of the device is being identified in the APP. After the device is successful, enter the product operation interface
4. If the identification device fails, restart the SpaceBot, turn off the APP, and continue the steps


Q1. Is MU the same as pixy camera?

A: It is a vision sensor same as pixy, but unlike pixy, it detects and tracks high level objects such as faces, human contours and balls. Pixy only tracks color blobs which are pruned to false alarms due to same color objects nearby or lighting changes.

Q2. How many objects can MU track at one go?

A: Due to the complexity of tracking, most of the algorithm will only track one largest object detected in the field of view.

Q3.How can I find the SN Retrieval for my MU?

A: Each MU has a unique SN (Serial Number) on the bottom of the package. SN is the certificate to upgrade firmware and to get the technical support from Morpx. If you lost your shipping box or need a SN for your MU PCB in the developer package, please follow the instructions from MU Firmware Upgrading Instructions(it contains the SN Retrieval Guide). Thanks!

Q4. Does MU work with Arduino and Raspberry Pi?

A: MU works with arduino and rpi. The last mode ("Vision Controller" mode), uses a UART port to communicate with these devices. I will send you a link to the UART protocol documents in a few days.


Q1.How do I put the MU on a LEGO EV3 set?

A:You can use a small, round, double-sided foam tape (included) and stick it near the IR sensor of EV3. For more details, please check our videos on YouTube or Tencent.

Q2. Could I use a MU to control LEGO® Power Functions IR Receiver(8884)?

A: Lego Power Functions IR receiver uses the same IR code as the EV3. So Mu can control both. For details please see this discussion.

Q3.Is this device programmable on EV3G software? Can we change the way it works on the EV3? Does it have to connect through the EV3 IR sensor?

A: MU acts exactly as the EV3 remote control. In this sense, you can program the behavior of this device on EV3 just like you program the software to use the remote control input. You will have to use the IR receiver for this version of MU.

Q4. Can I map the MU’s detection results to IR button on the EV3 Greeting Bot?

A: Currently the EV3 Greeting bot's control commands is nothing more than moving left and right motor towards the detected human,and spin a third motor to make the hand waving gesture. When MU detects a human on the left, it will press the left forward button. If the human is on the right, it will send the right forward button, so on and so forth. That means you can still use those button commands to program your EV3 even if your robot is not the Greeting Bot, as long as it uses left and right motors to do the movement. The EV3 Greeting Bot and EV3 snake are intended to give people more complete examples on what they can build using MU. This does not stop you to use those modes to control other form of EV3 robots.

Q5. Can I map the MU’s detection results to IR button on the EV3 Snake/ the EV3 Snake?

A: Please see the answer to the question “Can I map the MU’s detection results to IR button on the EV3 Greeting Bot?”

Q6. Where can I find the EV3 Snake’s building guide?

A: The EV3 snake is a slightly modified Rapt3r robot in the EV3 official guide. (

Q7. What does the MU’s snake mode do?

A: MU's snake mode will tracking and follow human, and after getting closer, attack! You will need to adjust MU's line of sight upward a bit to see people's upper body.

Q8. How can I know if MU's IR signal is received by the EV3 IR receiver?

A: Please check the following:
(1) When you turn on MU, it is by default in a standby mode blinking "red and blue" color, in the standby mode NO IR signal is send out. You should long press the mode button to switch to the EV3 model. After each long press, there is a voice prompt to indicate which mode MU is under.
(2) Please make sure EV3 IR receiver is connected to Port No. 4 on the EV3 brick, that is, your EV3 IR remote should be able to control EV3.
(3) Now please put MU close to the IR receiver. The IR sensor on the EV3 receiver is on the top middle part of the receiver. The Mu has two sets of IR transmitters. One set is in the front under the LED eyes. The other set is in the back by two sides of the USB connector. Please try to point these two sets to the top of the EV3 receiver and check if it receives the signal.
If you still cannot get MU to connect to EV3, please send a picture of your setup to and we could debug from there.

Q9. How can I get the information of what MU sees from within EV3?

A: Currently, MU will send out motion control signal to EV3, just like how you will control EV3 by pressing the remote control button.

Q10. Do you have a flow chart for your Lego EV3 applications?

A: Please see the following chart and table.

Please write your question and personal email, or send the question to, we will give you feedback soon.
