In this paper, a distributed motion control system is designed and achieved for the modular multi-legged robot with hand-fused foot based on CANopen network. A communication network is built among modules and joints through CANopen network. Controllers and encoders are used to achieve closed-loop control for each joint. The system has completed real-time multi-jointed linkage. Moreover, experimental results have proved the reliability and validity of this control system.

With the increase of urban car ownership and the development of computer technology and image processing technology, through the video detection of traffic information more and more important. This paper proposes a testing method of vehicle identification, and separately in grayscale matching, pattern matching and shape matching three methods respectively to test the vehicle, and respectively analyzes the three methods of accuracy and the reasons for the unreasonable data.
