Essentially, the project consists of three parts:
- The Lego modification
- It mainly consists of the modifications necessary to install the 4 additional motors.
- In addition, space for the controller and the battery must be found
- The adaptation of the controller to the hardware.
- A Raspberry Pi 3 is used.
- Since the motors are operated with 9V and can not be connected directly to the Raspberry Pi, an adapter board with motor drivers and step-up converter must be developed.
- The programming
- The remote control shall be done with a Wiimote, because there is a simple Python library.
- For programming, Python (2.xx) is used on Raspbian.
