A robotic surgical system for performing minimally invasive medical procedures includes a robot manipulator for robotically assisted handling of a laparoscopic instrument having a manipulator arm, a manipulator wrist supported by the arm and an effector unit supported by the wrist, wherein the manipulator arm provides three degrees-of-freedom by means of a first joint, a second joint and a third joint, each having an associated actuator, for robotically positioning the wrist, the wrist providing two degrees-of-freedom by means of a fourth joint and a fifth revolute joint having an associated actuator, for robotically setting the yaw angle and the pitch angle of the effector unit respectively; the effector unit includes a laparoscopic instrument actuator and provides one degree-of-freedom by means of a revolute sixth joint having an associated actuator for robotically setting the roll angle of the LIA which includes a seat, with an associated coupling mechanism for mounting an instrument stem adaptor to the effector unit, and an actuation mechanism cooperating with the instrument stem adaptor for actuating a laparoscopic instrument connected to the adaptor. The effector unit is configured such that the rotation axis of the revolute sixth joint coincides with the longitudinal axis of a laparoscopic instrument mounted to the effector unit and the effector unit includes a sensor assembly having a 6 degree-of-freedom (DOF) force / torque sensor and a 6 DOF accelerometer. The sensor assembly connects the LIA to the sixth revolute joint.

The present invention provides systems and methods for performing robotically-assisted surgical procedures on a patient. In particular, a three-component surgical system is provided that includes a non-sterile drive and control component, a sterilizable end effector or surgical tool and an intermediate connector component that includes mechanical elements for coupling the surgical tool with the drive and control component and for transferring motion and electrical signals therebetween. The drive and control component is shielded from the sterile surgical site, the surgical tool is sterilizable and disposable and the intermediate connector is sterilizable and reusable. In this manner, the intermediate connector can be sterilized after a surgical procedure without damaging the motors or electrical connections within the drive and control component of the robotic system.

A brick laying system where an operator such as a mason works proximate a moveable platform having a robotic arm assembly, a mortar applicator with a mortar transfer device, and a brick transfer device to build structures. The robotically assisted brick laying system may also contain a stabilizer having a disturbance sensing and a disturbance correcting component that provides compensation for disturbances caused by load shifting, movement of the platform, wind, operator movement, and the like. In addition, the robotically assisted brick laying system has a sensing and positioning component for controlling placement of the moveable platform and robotic arm assembly. The interoperability of the system with a mason or skilled operator removes much of the manual labor component of brick laying, allowing the mason more time to focus on craftsmanship and quality, thus improving the end product and the overall working conditions of the mason.
