The design and implementation of embedded Non-Line-of-Sight mobile robot based on ARM-Linux

According to NLOS(Non-Line-of-Sight) robot´s miniaturization and remote control technology requirement, a NLOS mobile robot control system based on embedded system technology, communication technology, imagine processing technology and sensor technology is raised, which puts an ARM9 processing chip S3C2410 as a controller and ARM-LINUX as a real-time operating system. Using H.264 video coding compression algorithm combined with USB camera image acquisition technology and wireless communication technology realizes real-time acquisition of environment image and wireless transmission; using fuzzy control algorithm and ultrasonic technology combined with robot tele-operation method realizes robot automatic obstacle avoiding and artificial remote control; using Internet technology realizes the NLOS real-time transmission of control instruction, scene image and environment variable. The simulation and experiments show that the robot control system can achieve flexible NLOS real-time control, transmit clear and successive image and also can realize automatic obstacle avoiding when encountering roadblock.
