Overview

DJI's first ground robot, a mecanum-wheeled tank with a gel-bead blaster and surprisingly good on-board vision, aimed at STEM education and games. The official API was locked to the app, which is why DJI later released the RoboMaster EP with a real SDK. DJI stopped selling it, but used units are plentiful and inexpensive.
