The electronics of the Coilinator 300V consist of 4 printed circuit boards, multiple sensors, motors and the name giving voice-coil.
Let us start at the bottom: Located on the base plate of the chassis are the drive motors, the battery and the base PCB. Mounted o top of it are the Raspberry Pi Zero W, the motor drivers, all the connectors and much more. From there, the signals go to the other components of the robot and thus it could be called the brain of the Coilinator. Attached to the motors are encoders, which are responsible for counting their turns. For additional orientation and acceleration measuring while driving, a 9-axis gyroscope is installed on the base print.
