This paper presents the design and analysis of a passive body weight (BW)-support lower extremity exoskeleton (LEE) with compliant joints to relieve compressive load in the knee. The biojoint-like mechanical knee decouples human gait into two phases, stance and swing, by a dual snap fit. The knee joint transfers the BW to the ground in the stance phases and is compliant to free the leg in the swing...
This paper presents the design of a sensor-guided gait-synchronization mechanism for a weight-support lower-extremity-exoskeleton (LEE), which provides motion to a (osteoarthritis or stroke rehab) passive leg in sync with the healthy (active) leg in the swing phase during walking. The gait synchronization system is integrated with a motorized hip-joint with embedded sensors that measure the angular...
This paper presents the design concept of a weight-support lower-extremity-exoskeleton (LEE) with a compliant joint to relieve compressive load in the knee. Along with a leg dynamic model and a knee bio-joint model, a compliant exoskeleton knee-joint has been designed using topology optimization and experimentally evaluated. Results suggest that the gait-based design of a LEE can be divided into two...
A motor-less fast climbing robot driven by fluid is introduced in this study. Designed with a simple five-linkage and one-piston mechanism, the robot has kinematics similar to a gecko's motion. Due to bionic design of gecko, the robot has an advantage of climbing fast on flat surfaces with any slope angles, even overhanging surfaces. Applied with fluid driven and fluidic vacuuming, the robot can carry...
