Cutting-Edge Equipment & Technology: Made of steel and finished with a sleek, futuristic design, the RoboMaster EP Core is fully equipped with cutting-edge technologies that provide consistent support for classroom learning.

• Robotic Arm: The EP Core’s Robotic Arm is incredibly durable, yet compact and flexible. It supports precise FPV control, allowing students to complete tasks even when the target objects are out of sight.
• Gripper: The Gripper transforms the EP Core into a powerful robot with multiple functions. A convenient structural design and adjustable gripping force empower it to firmly and reliably grasp and move objects of various shapes, weights, and sizes.
• Mecanum Wheels: The EP Core comes with four Mecanum wheels, each with 12 rollers that allow omnidirectional movement and precision control. Front axis suspension allows for added versatility during operation.
• High-Performance Servo: As a propulsion driver for the EP Core, the servo supports customized control abilities through the EP Core’s main control board. It ensures high control accuracy and large output torque. It can also power the Robotic Arm and allow students to build lifting structures using their knowledge of physics.
• Sensor Adaptor & Power Connector Module: Each sensor adaptor has two ports and provides power supply. A power connector module can connect and power third-party hardware, offering multiple ports to connect hardware and create custom programs and applications.
• Intelligent Controller: Using a powerful CPU, the Intelligent Controller can simultaneously support functions such as low-latency high-definition image transmission, AI computing, and programming development. It also coordinates transmission seamlessly to execute command signals.
• Infrared Distance Sensor: With a measurement range of 0.1-10 meters, the infrared distance sensor provides reliable distance measurement information. This enables the EP Core to sense its environment and avoid obstacles, deepening students’ understanding of advanced autonomous driving principles.
• High-Performance Motor: The EP Core comes with a customized motor that features an integrated FOC ESC with an output torque of up to 250 mN•m. Linear Hall-effect sensors with advanced algorithms allow closed-loop control for added precision. Additional safety mechanisms deliver outstanding stability.

Add Hardware, Unlock Creativity: The versatility to accommodate third-party hardware provides unlimited options for learning and unlocks students’ potential and imagination.

Increased Expandability: The versatility to accommodate third-party hardware such as building blocks and 3D printed objects provides unlimited options for learning and unlocks students’ potential and imagination.

Compatible with Third-Party Hardware: The RoboMaster EP Core 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.

Compatible with Third-Party Sensors: The RoboMaster EP Core is equipped with four sensor adaptors, making it convenient to connect and power third-party sensors that measure inputs such as temperature, pressure, distance, and more. Sensory data can even be used in Scratch, unlocking endless programming possibilities.

Real-World AI Implementation: Endless programming possibilities are unlocked when you use SDKs (software development kits). Open DJI SDK is available on the EP Core and supports more than 39 programmable sensor ports. This allows students to utilise streaming data from sensor modules, video, and audio to program AI applications and experience genuine AI technology.

Software Programming Platform: With the dedicated RoboMaster app, multi-platform interactions and various operation methods for the EP Core are supported, along with rich educational resources and several competition modes.

Resources: The EP Core comes with more than just a robot. DJI Education offers a custom curriculum, a competition database, and a variety of events to complete the classroom teaching and learning experience.

• Custom Learning Materials: Combining robotic theory with programming practice operations and tailored projects, the curriculum resources aim to drive students’ interests in engineering and cultivate their spirit of exploration. Lecture slides and lesson plans are provided to educators, worksheets and handouts are tailored for the students, and they all align with the most popular educational standards and are incredibly easy to follow, allowing smooth integration at multiple age and grade levels.
