Abstract
A surgical system for control of a surgical mechanical arm, which system comprises: at least one input arm comprising: a plurality of sections; a plurality of joints sequentially coupling said plurality of sections; at least one sensor configured to measure movement of one or more of said sections; and a weight attached to one of said plurality of sections which biases said one of said plurality of sections to a null configuration, by movement under gravity of said one of said plurality of sections about one or more of said joints; and circuitry configured to receive a measurement signal from said at least one sensor and to generate a control signal, based on said measurement signal for control of movement of said surgical mechanical arm.
