A surgical instrument holder includes a carriage, a housing, and a drive assembly. The carriage is configured for engagement to a surgical robotic arm and for supporting an instrument drive unit. The housing extends from the carriage and defines a channel. The drive assembly includes a pulley, a belt, and an annular member. The pulley is rotatably disposed within the housing and in operable engagement with a motor of the carriage such that actuation of the motor rotates the pulley. The belt is rotatably disposed within the housing and in operable engagement with the pulley such that rotation of the pulley effects rotation of the belt. The annular member is disposed within the channel of the housing and configured for non-rotatable receipt of an instrument drive unit. The annular member is in operable engagement with the belt such that rotation of the belt effects rotation of the annular member.

An object is to provide a mechanism that can ensure safe operation of a continuum robot. A block FTL calculates a target bending angle θ.sub.fFTL and a target rotational angle ζ.sub.fFTL of a following bending section on the basis of a target bending angle θ.sub.lt and a target rotational angle ζ.sub.lt of a distal-most bending section and a displacement of a base. A switch unit 330 selects the target bending angle θ.sub.fFTL and the target rotational angle θ.sub.fFTL of the following bending section obtained from the block FTL or a target bending angle θ.sub.lf and a target rotational angle ζ.sub.lf of the following bending section obtained from a block P.sub.l corresponding to following operating means. A kinematic computing unit 340 computes, on the basis of the target bending angle and the target rotational angle, a drive displacement by which a driving unit drives a wire in the following bending section.

Disclosed embodiments include a gantry assembly that has (i) a moveable carriage with a laser head affixed thereto and (ii) two sides (moveable subassemblies) that are connected by a joining subassembly. One side of the gantry has two motors: (i) a first motor (x-axis motor) that moves the carriage along a first axis (x-axis) between the two sides of the gantry, and (ii) a second motor (y-axis motor) that moves the gantry along a second axis (y-axis) perpendicular to the first axis. In some embodiments, the gantry assembly also includes a drive shaft (or alternative drive mechanism) operated by the second motor (y-axis motor) to facilitate movement of the two sides of the gantry together along the second axis (y-axis).
