Abstract: A robotic module which can be attached to an exercise apparatus provides enhanced physical therapy for victims of stroke or other maladies or accidents by simulating normal or arbitrarily modified profiles of angular position of an extremity such as a foot in accordance with a position of that extremity along a locus of repetitive motion.

Abstract: A robotic module which can be attached to an exercise apparatus provides enhanced physical therapy for victims of stroke or other maladies or accidents by simulating normal or arbitrarily modified profiles of angular position of an extremity such as a foot in accordance with a position of that extremity along a locus of repetitive motion. A closed-loop control system which is included in the module provides regulation which reduces or avoids spastic responses often found in poststroke patients during gait rehabilitation.

Abstract: A self initiated prone progressive crawler facilitates crawling in infants by sensing the infant's intent and assisting movement. The device is designed as a mobility aid to assist an infant in prone locomotion. The infant can be placed in a prone position on a platform and secured with hook and loop straps. The arms and legs are unconstrained and are able to reach the floor comfortably. The self initiated prone progressive crawler is a motorized wheeled platform which has three points of contact with the ground. One point is an industrial trackball, mounted upside down to provide positional and positional derivative data to a controller. It is located roughly under the chest of the infant and is highly sensitive to movement. The other points of contact are two DC torque motors which are controlled by the controller.
