Abstract
The present invention is a novel passive adjustable gravity compensation apparatus which utilizes an internal-pressure-variable cylinder. With the coordination of cam, rod, or the combination of the fore mentioned, the internal-pressure-variable cylinder obtains the characteristics of a linear elastic device which has variable elastic coefficient. Through appropriately adjusting the internal pressure of the internal-pressure-variable cylinder, the cylinder would perform as a linear elastic device with proper elastic coefficient to fully or partially compensate the gravitational effect of the manipulator system and the load it holds. Thus, the proposed invention can fully or partially compensate the gravitational effect of the manipulator system at different loading conditions without changing its geometric configuration.
