Songling Robotics LIMO is the world's first ROS development platform that integrates four motion modes, providing a learning platform that adapts to a wider range of scenarios and meets the requirements of industry applications, and is suitable for robotics education, functional research and development, and product development. Through innovative mechanical design, it can realize rapid switching of four-wheel differential, Ackermann, crawler-type, and McNamee wheel motion modes, and can quickly establish multi-scenario real simulation teaching and testing in the supporting professional sandbox.
