Abstract

Snake-like robots have many characteristics, such as strong motion stability and good environment adaptability. And these characteristics make them suitable to work under special environments, such as submarine and underground ducts, unevengrounds. So they attract the attention of scholars all over the world and become a new hot issue of research. This dissertation is mainly to research and design the control subsystem of a snake-like robot.

The movement mechanism of a snake-like robot is analyzed in this dissertation, and then three stages of a snake-like robot in motion, which are wave transmission, wave produces-transition and wave transmission, are studied in detail.

Secondly, based on thorough analysis of related control schemes and driving schemes, actuator is employed to realize the joint movement. The Microcontroller Unit is used as the core to control components, and the distributed control method is chose in the dissertation. Serial synchronous communication is used to realize the transmission of information between superior machine and lower computer. And the control circuit of the snake-like robot is designed in detail.

Finally, based on the hardware circuit of a snake-like robot, the program of snake-like robot control system is programmed.

The serpentine movement and telescopic movement of snake is studied, and Serpenoid curves are discretized, the forward movement, turn-left and turn-right movement of snake-like robot are simulated with MATLAB.

Keywords: snake-like robot; control system; Microcontroller Unit;simulation
