The crawler type autonomous mobile robot platform that can traverse over rough terrain was developed successfully. The snow remover “Oh! Snow” on the market was utilized as a base vehicle. T-frog motor driver was applied to make easy a system development. Also, the mechanism around a rotary encoder, and the control circuit box were designed and implemented in the robot platform. In the driving experiment on rough terrain in the golf course, it showed that the crawler type mobile robot platform could traverse over rough terrain stably. The crawler type mobile robot platform is useful for the system development of an autonomous mobile robot which can traverse over rough terrain.
