The RoverC is a programmable omnidirectional mobile robot base compatible with the M5StickC and can be started with the insertion of the M5StickC. The main controller of the base is the microcontroller stm32f030f4. The base comes with N20 worm gear motors, which are directly driven by a four-channel motor driver. These motors are connected to the mechanum wheels, which can move in all directions. In addition, two Grove-compatible I2C ports are provided to facilitate expansion to other modules.
