DJI RoboMaster EP

This multiple mode robot is the full version of the EP with three modes of functionality from DJI. It takes all the best of the drones from DJI and makes a terrestrial robot with an engineer mode, a combat mode, and a hybrid mode.

The modes use the same base chassis with interchanging tools for different tasks.

The robot features cutting-edge equipment and technology, is made of rugged steel, and finished with a sleek, futuristic design. The RoboMaster EP is fully equipped with cutting-edge technologies and integrates with additional technologies that provide an unrivaled platform for classroom learning. The EP includes the structural components:

1. robotic arm
2. gripper
3. Mecanum wheels
4. high-performance servo
5. sensor adaptor & power connector module
6. intelligent controller
7. infrared distance sensor
8. high performance motor.

The SDK from DJI provides a powerful programming environment to add more sensors (up to 40 more) and integrate with AI technologies. 

The RoboMaster EP even integrates with popular building blocks.

The RoboMaster EP supports third-party open-source hardware such as Micro:bit, Arduino, and Raspberry Pi. These items can be connected and powered via serial ports on the main controller of the chassis.

The EP Core can also perform model training and scene recognition through AI platforms such as NVIDIA Jetson Nano and the official DJI SDK, enhancing students’ understandings of the operating principles of AI.
