The error that occurs when uploading the sketch is shown below:
This "not in sync error" indicates a bad connection between your computer and your robot. It could be:
Usually, it can be fixed by the following checks:
Use the USB cable with the data function(the one included in the kit is good).
Select the correct board (Arduino Uno) and serial port
Connect the board and the programmer in the right pin order
Short melody
Power on or reboot
The program starts successfully
Short beep
During use
The program receives a command
Repetitive short melody
During use and pausing the movements
The battery is low or unconnected
There are two calibration steps for different components.
Because the controller board has limited resources, we divide the program into two stages.
In the first stage, we upload the program and large data to the onboard EEPROM (hard disk) and use the remaining programming space to calibrate the IMU, a sensor that measures the body orientation. The board should be leveled and untouched during the (IMU) calibration.
In the second stage, we upload the standard functional code. For the first-time configuration, we need to enter the (joint) calibration state and attach the legs in the right direction.
If you use the Arduino IDE to set up the board, you will handle those stages explicitly. The Petoi Desktop App can finish the two-stage uploading in the background. The smartphone app can work only with an already configured board. Its (joint) calibration is only for attaching the legs.
Remove the rubber toe covers
You can use python to control the robot. The scripts can work either on your computer and connects to the robot wired or wirelessly.
The toe covers are for special experiments that require more friction. They are not required for regular walking and performance. We have removed them from the standard kit recently and you may order them as optional accessories.
Both Bittle kit and pre-assembled Bittle include one Lithium battery with a built-in charging circuit. You may add more spare batteries.
You can solder the 2x5 socket on the NyBoard and then mount the Rasberry Pi on the NyBoard.

Yes, you still need to use the desktop app or smartphone app or Arduino IDE .
Our main board is specifically designed for our robots. The code is free to download on .
It follows your instructions via the infrared remote, smartphone app, or desktop app. It can also do random behaviors if you upload the random mode. Best of all, the program is open source on GitHub and you can refer to to create new skills for the robot.

Bittle can be programmed with a Scratch-like web-based IDE . You may find some complementary materials: and .
Note that CodeCraft hasn't provided support for our 2.0 version. But you may roll back to the supported version within CodeCraft or through .
You don't need to buy add-on components to use the basic functions in Codecraft. However, several extension functions require . If you are comfortable with coding with Arduino, you can have a much wider selection of third-party components.
