In this paper, we describe development of kinematic analysis for mowing device and motor controller for mowing robot on a slope. This robot,t raveling device use a crawler set to a low center of gravity. Mowing scheme was used which was reproduced using the mechanism (linkage mechanism), the reciprocating motion of the person when using herbicidal method mowing power. As a means of confirmation of the work area, the equation of motion was created to represent the trajectory of the link mechanism in two dimensions. As a result, I was able to link trail is modeled as a reciprocating motion of the arc from a formula. Program the remote control between the PC and the controller running the program has been completed. Therefore, promoting the development of a remote control system based on this program.
