The use of robotic assistive devices and exoskeletons to supply movement therapy for the rehabilitation of patients following variety of diseases is noticeably growing presently. In order to provide consistent therapy as well as walking assistance, we are developing a wearable lower-limb exoskeleton robot with an adaptive foot device for better walking ability and enhanced stability. In this paper,...
The satisfaction of constraints between the foot and the ground during balancing of bipedal standing is important. In this work, the effects of two constraints, namely the gravity constraint and the friction constraint, on balancing of a simplified two-dimensional biped are considered. The bounds imposed on the control torque are first determined analytically. Such results not only show the specific...
A new climbing robot has been developed that can scale flat, hard vertical surfaces including concrete, brick, stucco and masonry without using suction or adhesives. The robot can carry a payload equal to its own weight and can cling without consuming power. It employs arrays of miniature spines that catch opportunistically on surface asperities. The approach is inspired by the mechanisms observed...
