Product Profile
Introduction
The RoboMaster S1 is an educational robot inspired by the DJITM RoboMaster competition. The S1 offers comprehensive control and an immersive driving experience thanks to the omnidirectional chassis, agile Mecanum wheels, flexible gimbal, and stable, low-latency image transmission in first person view (FPV). Users can also target objects and battle other robots with the blaster.
The body of the S1 is covered in armor, and each piece has a hit detection module that can instantly detect physical hits and feed back to the intelligent controller. The blaster provides highlevel accuracy and stability thanks to the 2-axis gimbal while the launch trajectory light gives users a realistic and immersive experience.
The intelligent controller is integrated with multiple systems including a video transmission system, game system, and Scratch programming system. It includes six smart modules, including line recognition, vision marker recognition, person recognition, clapping recognition, gesture recognition, and S1 robot recognition.
The S1 supports Scratch and Python programming. With DJI’s project-based tutorials, users can gradually master programming theory and robotics knowledge.
The S1 also features Solo mode and Battle mode, where users can practice their skills and compete against others. To control the S1, the RoboMaster app can be used on a mobile device, the gamepad, or with a keyboard and mouse.

ROBOMASTER S1 User Manual
Avoid crashing into any objects at high speed.
Motion Controller
Overview
The motion controller is the core module for the S1 chassis movement, providing a rich external module interface for video transmission and connecting the gimbal, battery, armor, and motors. It also integrates an omnidirectional wheel motion control algorithm, power management system, motor management system, and a chassis management system.
