even play together at the same time. Users can also write programs easily and apply them or share with friends instantly using the
RoboMaster app. This section uses the RoboMaster app on iOS as an example. The specific interface may vary depending on the
device used.
Omnidirectional Chassis
The EP Core chassis is an omnidirectional motion platform based on the Mecanum wheels, which can be used to move forward,

traverse, skew, rotate, or a combination of movements at once.
Motion Controller
The motion controller is the core module for the EP Core chassis movement, providing a rich external module interface for video
transmission and connecting the battery, armor, and motors. It also integrates an omnidirectional wheel motion control algorithm,
power management system, motor management system, and a chassis management system.
Mecanum Wheel
The Mecanum wheel is a commonly used robotic omnidirectional chassis moving solution, which is divided into two types: left-
threaded and right-threaded. The four-wheeled chassis requires two pairs of Mecanum wheels.
When installing, you can check the left-threaded mark or right-threaded mark on the bottom of the chassis, and install the left-
threaded or right-threaded Mecanum wheel accordingly.
Armor Modules
A total of four armored modules are installed on the four sides of the EP Core chassis, which protect the internal structure of the
EP Core.
All armor is equipped with a hit detector, which is used to detect where the EP Core is struck and sends feedback to the intelligent
controller to deduct hit points from the corresponding hit point bar.
Each hit detector module is represented by an LED light and is visible under the armor module.
Intelligent Controller
The intelligent controller is integrated with multiple systems including a video transmission system, game system, and Scratch
programming system. It supports six smart modules, including line recognition, vision marker recognition, person recognition, clap
recognition, gesture recognition, and EP Core robot recognition.
