Abstract: Along with the progress of the society and the development of science, robot products play an increasingly important role in people's work environment .At home and abroad robots have become the hot topic. As a branch of the robot, the movement of hexapod crawled robots has strong stability, so it has an important meaning in military transport, astronomical detection and so on, and it also has been widely applied. To control the movement of hexapod crawled robots, A proposal was presented ，in which PLC acts as a main controller. In this proposal, advantages of PLC acting as the main controller in the process of control and achieve was put forward, and the hardware composing of the system was introduced in simply, the working process was analysesd and the choice of PLC certainness of various signals was expatiated on, the inputs and outputs was distributed, the interfaces was connected and the PLC was programed. Experiment shows that hexapod crawled robots was reliable and easy to control, and  it can overcome some problems of some other robots systems,  such as low security, low efficiency, hard maintenance and high cost.

Keywords: hexapod crawled robots, plc(Programmable Logic Controller), control, HMI(Human–Machine Interaction)
