Main electronics
Teensy Configuration
Figure: The main hardware blocks. Two Teensy processors are the interface to the hardware. The drive processor controls the drive motors, safety and battery system. The front processor controls the brush and the front wheel to lift the brush. A main PC integrates the functionality with additional sensors to allow autonomous operation.
Teensy firmware
Fejemis Teensy software is build using standard Arduino library configurations. The interface to the main PC is organized as text-lines.
Electrical
Fejemis electrical wiring etc.
