Design of a walking-aid and sit to stand transfer assisting device for elderly people

This paper describes the preliminary design of a light, high stability, robotic system for elderly assistance. The mechanisms used for such assisting devices must exhibit complex mechanical functions that may change during the use. The design was built up thinking about the constraints of a chosen pathology. Taking these constraints into account, the design of a robotic walker is presented which provide support during sit to stand transfer and during the walk.
