Features

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 Expand-ability

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 utilize streaming data from sensor modules, video, and audio to program AI applications and experience genuine AI technology.
