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 ...
