Humanoid leg could help amputees walk better
March 31, 2008
Researchers from the Institute of Field Robotics are using their knowledge of robot leg design in order to help human amputees walk easier.
The new "intelligent" leg is worn on the upper knee, and could one day act as an integrated part of the body. The leg detects the user's walking pattern and speed with sensors, and adjusts its dampening rate according to the individual. This customized design helps smooth out and dampen sudden shocks so that people can walk more naturally.
Data on the walking pattern is processed by an embedded microprocessor and built-in computer system, which calculates the optimal dampening rate for the user.
The institute is developing two other variations of the leg. In one model, users can manually adjust the dampening rate. In another model, the dampening rate can be adjusted wirelessly with a remote control, helping the leg to accommodate the user's optimal walking pattern.
