The main purpose of this research is to develop a new electrical trolley which possesses carrying capability of heavy loads and human body. The development of such novel product hold multifunction and modularize design. By using computer-aided-design software to set up 3D system model, the structure analysis and dynamic simulation have been demonstrated in this study. The system integration has been conducted by mechanism, electrical circuit, sensor and actuator. Thus, the operation performances have been verified in experimentation. Consequently, the development of new generation material handling-aided-machine will own multi-function and modularize design. The proposed novel device will own slope/stair climbing and descending. Moreover, it also owns carrying capability of heavy loads and human body. It also exhibits auto sensing function and multi safety prevention devices. It results in an intelligent handling-aided-machine of this product. Hopefully, the proposed novel device investigated in this research owns the potential to be developed into commercial products. It not only provides useful machine for material handling, but also can promote assistive devices market in Taiwan.
