Abstract
A device that attaches to three body segments connected by two joints harvests energy selectively from one of the two joints using a single motor-generator. The device also selectively augments relative body segment motion about one of the two joints. Selection of the harvesting or generating mode depends on the user's preference. When in a particular mode, the device automatically selects which of the two joints to connect to the motor-generator in order to optimize the augmentation or harvesting. Depending on whether the user is on flat terrain, going up an incline or down a decline, the selection of the joint to be connected is different. Use of a single motor-generator and gearbox mounted near the knee reduces metabolic cost compared to the use of two motor-generators and gearboxes.
