Robot laser range controller design based on embedded technology

In order to realize the advantages of easy portability,good control,low cost and high reliability of the robot laser ranging controller,we design the robot laser ranging controller based on embedded technology,which consists of two parts:the upper station and the lower station.The upper station displays,analyzes and manages the data from the lower station,which consists of a laser range collector,a direct controller and a display.The lower station collects the status and environmental data of the robot’s laser ranging and consists of an illuminated camera,GT8340 embedded control chip and motor driver.The control process of the GT8340 embedded control chip for the robot laser ranging was analyzed, as well as the connection structure and function of the upper unit,and the software design of the communication interface between the upper unit and the lower unit and the robot was carried out.The experimental results prove that the designed controller has small ranging error and short control delay time.
