Abstract
Automatic Immediate Fitting Socket (AIFS) system was developed to shorten the long, length of time for-making an artificial leg, by applying powder technology. A Fuzzy controller was applied for the real-time automatic control of the shape based on the subjective evaluation of the amputee. The surface contact pressure was evaluated during AIFS walking as well as the walking with the conventional socket. The pressure distribution using AIFS was more uniform than the conventional artificial legs. The shape modeling including test walking was completed in 30 minutes in all five amputees and practical shapes were obtained.
