Design of a terrain tentative sensing machine/sensor for a mobile robot

TTSMS is a typical four-link terrain tentative sensing machine/sensor. It can sense some parameters of the front terrain for mobile robots and simply process the sensing data to obtain a simple model of the terrain, and then instruct the robot to operate accurately in the uncertain terrain. The TTSMS features a simple structure and the capability of sensing a convexity-terrain. The principle of the TTSMS, its mechanical structure, the adoption of its parameters and the terrain-restriction condition of TTSMS are introduced in this paper. The TTSMS resolved the key problem of sensing obstacles in real time for mobile robots moving in a three-dimensional terrain environment .
