2、guz Kapti *, Gulcin Muhurcu Introduction Mobility of the lower extremity amputees relies very much on the prostheses. Control algorithms for robotic ankle systems in lower-limb or thoses, prostheses, and exoskeletons were reviewed in 1. And rysek provided a review for lower-limb prosthetic technolog
3、ies developed in last two decades 2. Martins et al. reviewed the state of the art in the robotic technology for mobility assistive devices developed for people with disabilities 3. They presented the important role of the robotics in mobility of the assistive devices existing on the literature, with
4、 the particular focus on the walking technologies. The researches in relation to the ankle joint behavior show that the ankle joint can be replaced effectively with passive mechanical devices 4. Many persons using transtibial prostheses with passive mechanical ankle-foot systems can walk with the ga
5、it patterns very closed to the able-bodied walkers at the slow walking speeds. One of the reasons making this possible is that the ability of the amputees to compensate for shortcomings of their prostheses reduces observable differences. Nevertheless, the actively controlled prosthetic systems are n
6、ecessary to mimic the ankle characteristics during walking at fast walking speeds and for other activities rather than level walking. In order to remove insufficient features of passive assistive devices, researches are being maintained for developing actively controllable lower extremity orthoses 5, and pros-theses such as Belgrade leg 6, an actively controlled above-knee prosthesis 7, Series Elastic Actuator 8,9, Sparky leg by Thomas G.
