With the widespread expansion and development of artificial intelligence, the robot are playing an increasingly important role in economic and the innovative application of science and technology. In some areas, robots are even more efficient than traditional projects led by humans themselves. When humans and robots work together, the position information of the human body is very important to the robots, because this information can not only improve the working efficiency of the robots, but also avoid the danger of users. So a complete system with a human body tracking and a well-controlled human-robot interaction function needs to be designed. Most of the existing detection technologies are based on cameras or single sensors, this design has obvious drawbacks. As the device free sensor can not be perfectly accurate, so it cannot be used to ensure safety as the only support. But as the camera may fail in certain situations such as occlusion, insufficient illumination, fault etc. The system needs some backup methods to ensure normal operation, so if a system has both a camera and a sensor system, then the device free sensor can take over when the main sensor (camera) fails. This thesis focuses on the evaluation of the device-free sensor when the main sensor fails to function. This thesis mainly introduces a evaluation of device-free system based on the Bluetooth sensor network. and some control methods to allow the robot to work harmoniously with people instead of becoming a hidden danger.
