Abstract
This paper presents the development of a new step-climbing mechanism for heavy load carrier. According to the measurement method presented, experimental results are given as the values of resistant force and possible power against 10mm step. The basic design of the proposed mechanism is illustrated, and its prototype is manufactured. Measured impact acceleration using the prototype, it was to be verified the accuracy of the mechanism CAE analysis. In addition, using the mechanism CAE analysis, we revealed the relationship between the angle and link length and the performance. The results from several experiments demonstrate that this prototype is able to drive over the target step 10mm effectively. It is, therefore, shown that the proposed mechanism is effective for driving over a step.
