Maker Mini Sumo Controller - controller for Mini Sumo robots

Description

The controller is dedicated to Mini Sumo robots, compatible with Arduino Nano and Arduino Uno boards. It is a great solution for beginners who would like to start playing with sumo robots, but are not yet able to fully design the control electronics themselves. The module can power two DC motors with a current consumption of up to 3 A (continuous current). The user has the option of connecting numerous sensors necessary in robot fights, including enemy sensors, edge sensors, but also a starting module and a servo. The board has buttons that allow you to easily test the operation of the drives. The module is supplied with the voltage ranging from 7 to 18 V and has protection against reverse battery connection. An interesting solution is the use of a shockproof on / off switch with a MOSFET snap circuit, which prevents the robot from being accidentally turned off in the event of a crash. The controller does not require soldering, and all elements are connected via screw connections. The library with the description of the configuration are available in the project's GitHub repository.
