In order to obtain haptic interaction with precise force feedback from the environment, for an exoskeleton, a robotic 2-jaw gripper is proposed. To reach this goal, a gripper is designed based on optimizing the link lengths to maximize the amount of

Efficient actuation is an important requirement in electromechanical designs. Although hydraulic actuators are used extensively when high-magnitude forces are present in heavy machinery, they are not very energy-efficient. This paper aims to increase
