Publication number: 20230356388Abstract: Multi-segment manipulator arms are provided that exhibit improved performance in space applications, include reduced weight, reduced cost, reduced size, reduced rotational inertia, reduced vibration, improved heat dissipation characteristics, and increased reliability and on-station reparability. These manipulator arms transmit torque from a single motor at the base of the arm to each of the inter-segment joints via serial belts, rotationally linked via pulleys that are coaxial with the inter-segment joints. Brake(s) at each joint allow all but a selected joint to be fixed, allowing motor torque to be transmitted to the un-fixed joint, applying torque and/or rotation to the un-fixed joint. Placing the motor at the base facilitates heat management, reduces overall weight, and reduces total rotational inertia and weight of the arm segments.Type: ApplicationFiled: August 2, 2021Publication date: November 9, 2023Inventors: Thomas P. LOW, Brian FOSTER, Brian K. MCCOY

Patent number: 9272425Abstract: A twisted string actuator system includes a motor generating rotary motion of a rotor and a twisted string comprised of a pair of cords. One end of the twisted string is attached to the rotor and an opposite end of the twisted string is coupled to a load.

The first and second sections of the twisted string are on a first side and second side, respectively, of the cord guide. Rotary motion of the rotor in one direction operates to twist the pair of cords on the first side of the cord guide while pulling a portion of the pair of cords from the second side of the cord guide into the first side.Type: GrantFiled: June 22, 2015Date of Patent: March 1, 2016Assignee: SRI InternationalInventors: Pablo E.

Patent number: 9130484Abstract: An electroadhesive gripping system includes a vacuum-augmented gripper. The gripper can include an electroadhesive surface associated with one or more electrodes and a load-bearing backing structure coupled to the electroadhesive surface. The backing couples to the backside of the electroadhesive surface so as to at least partially define a shape of the electroadhesive surface. The backing is configured to flex between a curled shape and an uncurled shape. A spreading arm is configured to apply force to the backing so as to flex the backing from the curled shape to the uncurled shape. When positioned next to a substrate, the uncurling motion of the backing can cause the electroadhesive surface to become vacuum sealed to the substrate. A power supply can be configured to apply voltage to the electroadhesive surface.Type: GrantFiled: October 11, 2013Date of Patent: September 8, 2015Assignee: SRI InternationalInventors: Harsha Prahlad, Thomas P.

Patent number: 9093926Abstract: An electroadhesive gripping platform includes one or more electrodes. A power supply is configured to apply voltage to the one or more electrodes in the electroadhesive platform via one or more terminals. A controller is configured to operate the electroadhesive gripping platform to selectively adhere to items loaded thereon and thereby enhance traction control over such items. The controller can control the power supply to apply a voltage to the one or more electrodes in the electroadhesive platform to thereby cause the electroadhesive platform to adhere to an item disposed on the electroadhesive platform such that the item resists moving with respect to the electroadhesive platform. The controller can also control the voltage supply to reduce the voltage applied to the one or more terminals such that the item moves with respect to the electroadhesive platform.Type: GrantFiled: May 2, 2013Date of Patent: July 28, 2015Assignee: SRI InternationalInventors: Harsha Prahlad, Ronald E.

Patent number: 8833826Abstract: Robotic hands and finger modules include an underactuated finger with multiple joints including a distal joint, an intermediate joint, and a proximal joint. A brake subsystem in communication with each of the joints selectively locks and unlocks the joints individually. A robotic hand can selectively lock the joints of a finger individually such that one or more joints are locked while one or more joints are unlocked. In addition, the finger module can drive a tendon coupled to the joints to flex the underactuated finger in a manner determined by which of the joints is locked and which of the joints is unlocked. A robotic hand can move an underactuated finger with its distal and proximal joints unlocked until the finger makes contact with an object, and lock the proximal joint, in response to contact made with the object, while the distal joint remains unlocked.Type: GrantFiled: March 21, 2012Date of Patent: September 16, 2014Assignee: SRI InternationalInventors: Pablo E.
