DJI Robomaster S1 Educational DIY Robot

The DJI Robomaster S1 Educational DIY Robot is an unprecedented and engaging way to explore the world of robotics. The design was inspired by DJI's annual RoboMaster robotics competition, a contest founded in 2015, with over 20,000 students from more than 400 schools participating. The thrilling program tests wit, engineering, and problem-solving skills. The results of this competition have been collected and used to create this exciting design. The S1 provides users with an in-depth understanding of science, math, physics, programming, as well as captivating game-play modes and intelligent features. 

Maneuver and explore your environment with this interesting and interactive robot. Use FPV technology to scout ahead and pick targets for the mobile turret or other accessories (not included) to engage. The robot uses sensitive armor panels and intuitive AI to detect infrared or gel beam strikes, allowing the user to interact and battle other Robomaster kits. AI technology lets the S1 recognize gestures, sounds, and even other S1 robots. Playing with the RoboMaster S1 opens the doorway to AI learning, giving you a practical introduction to the technologies of tomorrow. 

Up to 46 customizable components are available to give you unlimited space for innovation, enabling you to grow and learn in an exciting way that expands the capabilities of your S1, and yourself. Six PWM port and one SBus port support customized accessories, granting further options. Operate your S1 with a remote controller that supports SBUS protocol, or program complex codes with an external development board to explore the unlimited possibilities of the S1 and the magic of the robotic world.
