Overview
RoboMaster EP Core uses an omnidirectional chassis and Mecanum wheels. The robot offers
comprehensive control and an immersive driving experience thanks to the omnidirectional chassis,
agile Mecanum wheels, and stable, low-latency image transmission in rst-person view (FPV).
The robot uses a gripper and an agile robotic arm to grasp and move objects. The gripper and
robotic arm are driven by two high-performance servos.
A customizable extension platform allows users to build and expand the robot any way they choose.
The robot is also compatible with third-party building blocks, providing even more ways to learn and
have fun.
Open DJI SDK is available on the robot and supports 39 programmable sensor ports. It is also
compatible with third-party hardware, providing users with unlimited creative possibilities.
