Patent number: 8560118Abstract: Methods, devices (such as computer readable media), and systems (such as computer systems) for performing movements of a tool of a medical robot along a single axis that are achieved by electronically limiting the medical robot's movement to produce movement of the tool along the single axis rather than mechanically restricting the medical robot's movement to produce the single axis movement. The tool's movement will be along the single axis even if a user is moving an input device linked to the medical robot in other axes during the single axis movement. In addition, techniques are disclosed for automating the single axis movement such that it can be programmed to stop at a target location and start at or near a second (e.g.Type: GrantFiled: April 16, 2008Date of Patent: October 15, 2013Assignee: NeuroArm Surgical Ltd.Inventors: Alexander Greer, Garnette Sutherland, Tim Fielding, Perry Newhook

Patent number: 8548628Abstract: The invention relates to a method and to a system for aligning and controlling the position of a robot tool, wherein a monitoring device is equipped with a detection unit and processing unit which co-operates with the control device of the robot and automatically determines the alignment of the robot tool by means of the detection unit by taking into account at least one pre-determined reference direction of the robot tool, in addition to at least one predetermined tolerance angle which defines a tolerance range for the at least one reference direction of the robot tool. The processing unit compares the determined alignment to the predetermined reference direction and/or to the tolerance values predetermined by the defined tolerance range and/or of the at least one tolerance range is not respected, the respective robot tool is disconnected and/or deactivated in co-operation with the control device of the robot.Type: GrantFiled: November 15, 2006Date of Patent: October 1, 2013Assignee: ABB AGInventor: Sönker Kock

Publication number: 20130098190Abstract: A mechanical manipulator includes a base seat, a connecting arm, a mechanical arm, an electric cable, and a cable protection structure. The connecting arm has a first end rotatably hinged to the base seat, a second end opposite to the first end, and a side surface, the connecting arm defines a cable receiving slot in the side surface. The mechanical arm is rotatably hinged to the second end of the connecting arm. The electric cable is partially received within the cable receiving slot. Two ends of the electric cable are exposed from two ends of the cable receiving slot and then enter into the base seat and the mechanical arm respectively. The cable protection structure is fixed to the connecting arm and resists against the electric cable toward the cable receiving slot, for preventing the electric cable emerging from the cable receiving slot.Type: ApplicationFiled: June 27, 2012Publication date: April 25, 2013Applicants: HON HAI PRECISION INDUSTRY CO., LTD., Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd.Inventor: XIAO-PENG PAN
