With focus on various interfaces of robotic sensors, a scheme based on IEEE1451.4 is advanced in this paper, with the purpose of the standardization of roboticc sensor interfaces. This standard realizes the intelligence of the robot sensors by endowing them TEDS, and it solves some of the problems due to sensors' differences. Sensor Plug-and-Play is achieved by using this standard on this foot robot perception system, and configuring TEDS of the sensors on PC is predigested by Labview,.
