The platform realized the all-round wheel structure designs, which can flexible complete mobile operation, and have good adaptability to the environment. At the same time, the platform combined the Internet of things technology and robot technology, realized intelligent ob- stacle avoidance, indoor positioning, data relay and other functions, which had good ability of data processing and expansibility. Through practical verification, this platform can realize human-machine interaction and reliable operation, which has a broad application prospect.
