Prosthetic design and prototype development
2020
Abstract In recent years, there has been worldwide interest in improvement of the mobility of people with lower-limb amputations. Despite significant development of new technologies over the last decade, commercial below-knee and above-knee prostheses are still energetically passive devices. However, many locomotive functions, like walking up stairs and slopes, need significant power in the knee and ankle joints. The additional power for carrying out these previously mentioned activities needs to be achieved by means of external energy sources, which should be integral prosthetic components. This chapter presents preliminary investigations and development towards an active robotic prosthesi…
