Abstract
In our laboratory, we have developed a remote controlled mower robot, AMR-D01. However, it has several weak point such as it takes time to work, grass which is not mowed hit against front body because its blade diameter is small. In this paper, an oscillating mower mechanism for mower robot is proposed in order to increase the swath of the robot. This mechanism is based on Lever-crack mechanism, which has a rotary link, a transmission link, an oscillation link, a fixed link. Characteristics of the mechanism, such as angle of oscillation and quick return ratio of the oscillation link, required torque of the rotary link, with ratio patterns of length of each link is evaluated by simulating. From the results, proper design and parameters are selected. Proposed mower robot have the advantages of reduced mowing time and costs using the oscillating mower mechanism.
