Abstract
A robot for spinal surgery may include an open rectangular base designed to slide on a rail of a fixed support to reach to different parts of the spine. The robot may include a moving top platform that can accommodate a surgical instrument, and three legs to support the top platform on the base and move the top platform in 6-degree-of-freedom relative to the base. In one embodiment, each of the three legs may include a lower part and an upper part joined by an electric linear actuator for sliding the upper part linearly relative to the lower part. In one embodiment, the lower part of each leg may be joined to a shaft of a rotary actuator that is mounted to the base, and the upper part of each log can be joined to the top platform at a fixed point via a passive spherical joint.
