The goal of this study was to find an efficient method of energy transmission for application in an anthropomorphic underactuated body-powered (BP) prosthetic hand. A pulley-cable finger and a hydraulic cylinder finger were designed and tested to compare the pulley-cable transmission principle with the hydraulic cylinder transmission principle. Both fingers had identical dimensions and a low mass. The only thing that differed between the fingers was the transmission principle. The input energy was measured for a number of tasks. The pulley-cable finger required more input energy than the hydraulic cylinder finger to perform the tasks. This was especially the case in tasks that required high pinch forces. The hydraulic cylinder transmission is therefore the more efficient transmission for application in BP prosthetic fingers.
本研究的目标是找到一种高效的能量传输方法，用于拟人化欠驱动身体驱动（BP）假肢手。设计并测试了滑轮-缆索手指和液压缸手指，以比较滑轮-缆索传动原理与液压缸传动原理。两个手指尺寸相同且质量轻。手指之间唯一的区别是传动原理。测量了一系列任务的输入能量。完成这些任务时，滑轮-缆索手指比液压缸手指需要更多的输入能量。在需要高捏力的任务中尤其如此。因此，液压缸传动在BP假肢手指中的应用更高效。
