Abstract

An active vibration isolation system for isolating a suspended platform from vibration input to the vibration isolation system base includes an exoskeleton which supports the suspended platform relative to the base. The exoskeleton includes first and second scissors mechanisms with main links of unequal length. The main links pass through a parallel condition as the suspended platform moves over its intended range of travel relative to the base. The vibration isolation system may include a rotary actuator and a drive mechanism separate from the exoskeleton for providing force output from the rotary actuator to the suspended platform. The rotary actuator may include inner and outer rotors which rotate relative to each other and may be free to rotate relative to the exoskeleton. The rotary actuator may be free to translate relative to the vibration isolation system base and the suspended platform.
