Abstract
Wheeled robots usually move fast in relatively even surfaces while losing their major mobility on rough terrains. However, the tracked robots are superior to the wheel-types when they are to move on irregular terrains in spite of lower speed. In this paper, a Wheel-Track Transformation robot which combines the advantages of both mobile types by turning into wheel mode or track mode is designed. The robot consists of a robot platform equipped with an extra support mechanism, two wheels with transformation units and an universal wheel. Each transformation unit is composed of a rotating board and a double two-bar linkage mechanism. Three key mechanical components and several locomotion strategies on rough terrains are presented. Meanwhile, a detailed quasi-dynamic analysis is conducted to obtain proper torque capabilities of motors. Three prototypes of the proposed mechanism were manufactured and their fundamental mobility was evaluated by experiments.
