A wheeled robot with a module slot on the front, allowing module attachments wirelessly through pogo pins. Driven by two motors in the rear and controlled by a joystick mounted on top.
I've previously made a robot that is sort of modular, but you need to connect the wires together and use the janky pins to attach them to the base. I wanted to create a new robot with an improved system completely wireless.
Includes:
- Power management
- Motor driver
- Wireless module interface (pogo pins)
- Microcontroller hub
- Headlights module
Smooth, round base with a flat front for module additions. Detachable lid for battery and PCB.
Simple shell for the headlights module to be contained in.
Simple lightweight wheels with slots for motor shaft.
