Outline of Final Research Achievements

We studied the minimum structure and specifications of the drive mechanism for human motion assistance device. Multithread worm and helical gear combination was proposed, and from the life time limit test result, we confirmed the material LT625 was longer than Albc. Furthermore, we found the micro miniature servo motor for hobby was good specification from the viewpoints of small, light-weight, and reasonable for human assistance device. To be able to use it continuously, we developed the torque limiter which can include in the gear. We confirmed the maximum transmission torque and maximum load repetition number for each material.
