A robotic kit can assemble to a mechanical robot with certain function, it’s an application of electronics, mechanics, and programming tools to program robot to do certain task. In education, the robot system includes controller, sensor, execution part, moving chassis, power supply, and connecting parts. By creating a robot with a robotic kit, users can learn and practice multiple subject knowledge such as math, science, physics, mechanical engineering, electronics, art, programming, etc. It’s an ideal carrier of STEAM education application by project-based learning. The cross-subject education with robotic kit will widely expand user’s ability to different themes, such as robot design, smart home, the Internet of Things, artificial intelligence and so on.
