Patent number: 9556920Abstract: A planar flexure member for resisting rotation about a central axis thereof includes, in various embodiments, a central portion comprising a plurality of attachment points; and at least one serpentine flexure arm extending from the central portion in a plane. The arm(s) terminate in an arcuate mounting rail that includes a series of attachment points. The rails are positioned in opposition to to each other to partially define and occupy a planar circular envelope radially displaced from but surrounding the central portion of the flexure member. A portion of the serpentine arms may extend to (or substantially to) the envelope between the mounting rails.Type: GrantFiled: July 23, 2015Date of Patent: January 31, 2017Assignee: Rethink Robotics, Inc.Inventors: Matthew Knoll, Jonathan Bond, Robert White, Umberto Scarfogliero, Andrew Wallace

Patent number: 9221172Abstract: Redundant robotic manipulators may be constrained in their motions during operation in a gravity-compensated mode by applying, in addition to gravity-compensating torques, constraining torques to one or more of the joints. The constraining torques may urge the manipulator to a specified canonical posture, and may be modeled by virtual springs attached to the constrained joints.Type: GrantFiled: September 17, 2013Date of Patent: December 29, 2015Assignee: Rethink Robotics, Inc.Inventors: Matthew Murray Williamson, Matthew DiCicco, Joseph M.

Patent number: 9114536Abstract: Representative embodiments of a system for braking a cyclically rotating motor upon a power failure include (i) charge-storage circuitry for storing charge and converting the stored charge to an output voltage upon power failure; (ii) one or more passive electrical elements for conducting current induced by motor rotations; and (iii) voltage-actuated circuitry connected to the passive electrical element and the charge-storage circuitry for braking the motor during each half-cycle of motor rotation. The circuitry is inactive until actuated by the charge-storage circuitry upon power failure.Type: GrantFiled: April 13, 2012Date of Patent: August 25, 2015Assignee: Rethink Robotics, Inc.Inventor: Michael Sussman
