Automatic lower limb actuator, for ankle and knee.
This device is similar on view to a body scale. The user sits confortably and puts his feet on the pedals, which alternately move onwards and backwards, roughly simulating the act of gait.
Walking is well known to have benefits on cardiovascular and musco-skeletal systems, preventing varicose veins, edema, bone resorption and tendons/ligaments stiffening. Therefore, the Automatic limb actuator is suitable for those people who dont'have enough opportunities to walk in their everyday life, such as sedentary workers or elderly people with difficults to walk independently.
The device works with AC power supply, has tunable height and inclination, various moving speeds to choose, and can be safely used even for several hours continuously.
The project is freely inspired by the commercial model HappyLegs (by AutoErgon, Spain), aiming to offer a cheap and open-source version of the actuator.
