Gravity compensation of an upper extremity exoskeleton [PDF]
2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010 This paper presents a new gravity compensation method for an upper extremity exoskeleton mounted on a wheel chair. This new device is dedicated to regular and efficient rehabilitation training for post-stroke and injured people without the continuous presence of a therapist. The exoskeleton is a wearable robotic device attached to the human arm.

An active Z gravity compensation system [PDF]
Proceedings of 1993 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS '93), 2002 To perform simulations of partial or microgravity environments on earth requires some method of compensation for the earth's gravitational field. The paper discusses an active compensation system that modulates the tension in a counterweight support cable in order to minimize state deviation between the compensated body and the ideal weightless body ...

Design and Evaluation of AX-Deminer Forearm Assistance for Demining Soldier
IEEE Access, 2023 Mine clearance operation using a mine detector often strains arm muscles because of the extended form of the detection pole. Implementing a gravity compensation device may be beneficial for alleviating this issue.

A slow gravity compensated atom laser [PDF]
Applied Physics B, 2010 We report on a slow guided atom laser beam outcoupled from a Bose-Einstein condensate of 87Rb atoms in a hybrid trap. The acceleration of the atom laser beam can be controlled by compensating the gravitational acceleration and we reach residual accelerations as low as 0.0027 g. The outcoupling mechanism allows for the production of a constant flux of 4.
