Simulation and analysis of a TET-walker robot motion
(IEEE, 2014)Tetrahedral walker robots are a group of reconfigurable robots which makes them adaptable for the full spectrum of activities in places that wheeled robots are inapplicable. In this paper, two different gaits for a ... -
Simultaneous improvement in strength and ductility of severely deformed niobium alloy
(Elsevier, 2020-11-15)The present study is on the improved monotonic response of a severely deformed niobium-based alloy. Nb-1Zr alloy was processed at room temperature using equal channel angular extrusion and cold rolling. After 16 passes, a ... -
Sliding mode control of an electromechanical solenoid actuator for soft landing
(IEEE, 2018-10-08)Electromechanical solenoid actuators are widely used in industrial applications that require fast and linear motion. High velocities can be achieved in small stroke lengths; in turn the motion results with high-velocity ... -
A soft+rigid hybrid exoskeleton concept in scissors-pendulum mode: A suit for human state sensing and an exoskeleton for assistance
(IEEE, 2019-06)In this paper, we present a novel concept that can enable the human aware control of exoskeletons through the integration of a soft suit and a robotic exoskeleton. Unlike the state-of-the-art exoskeleton controllers which ... -
