*The patient cart. (a) The visual pad on the patient cart that allows operator to set the type of surgery to be performed and the handles that allows the patient cart to be moved around theatre. (b) A robotic arm with an instrument in place. The port and instrument clutches can be utilised to move the instrument into the correct position. Setting set-up it must be ensured that the robotic arms are in the correct alignment to avoid unnecessary collisions and clashes between arms.*

The cart also contains an electrosurgical unit, the light source for the 3D endoscope and a series of racks for optional auxiliary surgical equipment such as recording facilities.
