US Patent:

20110043537, Feb 24, 2011

Filed:

Aug 20, 2010

Appl. No.:

12/860296

Inventors:

Brian Dellon - Seattle WA, US
Yoky Matsuoka - Medina WA, US

Assignee:

University of Washington - Seattle WA

International Classification:

G09G 5/00

US Classification:

345647

Abstract:

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.

Appl. No.:

13/153614

Inventors:

Brian Dellon - Seattle WA, US
Yoky Matsuoka - Palo Alto CA, US

Assignee:

University of Washington Through Its Center for Commercialization - Seattle WA

International Classification:

F16H 1/00

US Classification:

7449001, 7449002, 901 48

Abstract:

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).

Appl. No.:

15/386767

Inventors:

- Mountain View CA, US
Brian Dellon - West Roxbury MA, US

International Classification:

B25J 9/14
B25J 17/00
F16H 25/12

Abstract:

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.

Assignee:

BOSTON DYNAMICS, INC. - Waltham MA

International Classification:

F16H 25/12

US Classification:

74 8923

Abstract:

An actuator includes an outer sleeve with at least a pair of helical slots coiling in a first direction, an inner sleeve with at least a pair of helical slots coiling in a second, opposite direction, and a driver including bearings received through the helical slots of the inner sleeve and into the helical slots of the outer sleeve.
