Publication number: 20230311346Abstract: A robot includes an input link, an output link, and a wire routing. The output link is coupled to the input link at an inline twist joint where the output link is configured to rotate about the longitudinal axis of the output link relative to the input link. The wire routing traverses the inline twist joint to couple the input link and the output link. The wire routing includes an input link section, an output link section, and an omega section. A first position of the wire routing coaxially aligns at a start of the omega section on the input link with a second position of the wire routing at an end of the omega section on an output link.Type: ApplicationFiled: June 7, 2023Publication date: October 5, 2023Inventor: Brian Dellon

Patent number: 11613024Abstract: A gripper mechanism includes a pair of gripper jaws, a linear actuator, and a rocker bogey. The linear actuator drives a first gripper jaw to move relative to a second gripper jaw. Here, the linear actuator includes a screw shaft and a drive nut where the drive nut includes a protrusion having protrusion axis expending along a length of the protrusion. The protrusion axis is perpendicular to an actuation axis of the linear actuator along a length of the screw shaft. The rocker bogey is coupled to the drive nut at the protrusion to form a pivot point for the rocker bogey and to enable the rocker bogey to pivot about the protrusion axis when the linear actuator drives the first gripper jaw to move relative to the second gripper jaw.Type: GrantFiled: November 2, 2020Date of Patent: March 28, 2023Assignee: Boston Dynamics, Inc.Inventor: Brian Dellon

Patent number: 10399219Abstract: An example device may include a rounded outer incline ramp and a rounded inner incline ramp surrounding a central axis. The rounded inner incline ramp and the rounded outer incline ramp may be inversely aligned relative to the central axis. The device may also include a piston carrier oriented in a direction parallel to the central axis. The piston carrier may include a first piston including a first roller positioned on the two ramps at a first point, where the first piston is configured to act on the two ramps in a direction parallel to the central axis. The piston carrier may also include a second piston including a second roller positioned on the two ramps at a second point opposite the first point, where the second piston is configured to act on the two ramps in a direction parallel to the central axis.Type: GrantFiled: December 21, 2016Date of Patent: September 3, 2019Assignee: Boston Dynamics, Inc.Inventor: Brian Dellon

Patent number: 8621954Abstract: Disclosed herein are systems and methods that may compensate for the effect of gravity on certain haptic devices, such as haptic-robot devices. An example embodiment of the disclosed systems and methods may take the form of a gravity-compensation system that includes (a) a carriage coupled to a rod having a first axis, wherein the carriage is configured to move along the first axis, (b) a displacement mechanism coupled to the carriage, wherein the displacement mechanism is configured to move the carriage along the first axis of the rod based on a displacement of an extendable arm along the first axis, and (c) a restorative-force mechanism configured to exert, on the carriage, a restorative force that acts along a second axis. The gravity-compensation system acts in a primarily passive manner, helping to ensure the safety of users at the point of human-robot interaction (pHRI).Type: GrantFiled: June 6, 2011Date of Patent: January 7, 2014Assignee: University of Washington Through Its Center for CommercializationInventors: Brian Dellon, Yoky Matsuoka

Publication number: 20110043537Abstract: A safe, purely dissipative, robotic device and method for rehabilitation of large whole body movements, for example, in stroke victims. Shifting to passive actuation fundamentally changes common control strategies that work well for active devices. The novel approach distorts visual feedback to the subjects as a first step to achieve the desired controllability hereto limited by passivity constraints. With visual distortion, a subject's arm trajectory can be altered in a way that passive actuation alone cannot. Results show that subjects involuntarily changed their path motion up to 30% with distortion applied. This ability to steer user's movements can be harnessed to offset controllability issues.Type: ApplicationFiled: August 20, 2010Publication date: February 24, 2011Applicant: University of WashingtonInventors: Brian Dellon, Yoky Matsuoka
