Patent number: 11932332Abstract: An example robot includes a first actuator and a second actuator connecting a first portion of a first member of the robot to a second member of the robot. Extension of the first actuator accompanied by retraction of the second actuator causes the first member to roll in a first roll direction. Retraction of the first actuator accompanied by extension of the second actuator causes the first member to roll in a second roll direction. A third actuator connects a second portion of the first member to the second member. Extension of the third actuator accompanied by retraction of both the first and second actuators causes the first member to pitch in a first pitch direction. Retraction of the third actuator accompanied by extension of both the first and second actuators causes the first member to pitch in a second pitch direction.Type: GrantFiled: April 13, 2021Date of Patent: March 19, 2024Assignee: Boston Dynamics, Inc.Inventors: Christopher Everett Thorne, John Aaron Saunders, Marco da Silva, Thomas H.

Patent number: 11407107Abstract: A method for palletizing includes receiving a target box location for a box grasped by the end-effector, the box having a top surface, a bottom surface, and side surfaces. The method also includes positioning the box at an initial position adjacent to the target box location and tilting the box at an angle relative to a ground plane where the angle is formed between the ground plane and the bottom surface. The method further includes shifting the box from the initial position in a first direction to a first alignment position that satisfies a threshold first alignment distance, shifting the box from the first alignment position in a second direction to the target box location that satisfies a threshold second alignment distance, and releasing the box from the end-effector. The release of the box causes the box to pivot toward a boundary edge of the target box location.Type: GrantFiled: March 12, 2020Date of Patent: August 9, 2022Assignee: Boston Dynamics, Inc.Inventors: Neil Neville, Kevin Blankespoor, Jennifer Barry, Alexander Douglas Perkins

Patent number: 10719085Abstract: A method of operating a robot includes assuming a resting pose of the robot on a surface. The robot includes an inverted pendulum body, a counter-balance body disposed on the inverted pendulum body and configured to move relative to the inverted pendulum body, at least one arm connected to the inverted pendulum body and configured to move relative to the inverted pendulum body, at least one leg prismatically coupled to the inverted pendulum body, and a drive wheel rotatably coupled to the at least one leg. The method also includes moving from the resting pose to a sitting pose by moving the counter-balance body relative to the inverted pendulum body away from the ground surface to position a center of mass of the robot substantially over the drive wheel. The method also includes moving from the sitting pose to a standing pose by altering a length of the at least one leg.Type: GrantFiled: February 22, 2018Date of Patent: July 21, 2020Assignee: Boston Dynamics, Inc.Inventor: Alexander Douglas Perkins

Patent number: 10550860Abstract: In some applications, a piston of a hydraulic actuator may move at high speeds, and large undesired forces may be generated if the piston reaches an end-stop of the hydraulic actuator at a high speed. The undesired forces may, for example, cause mechanical damage in the hydraulic actuator. A controller may receive information indicative of the piston reaching a first position at a first threshold distance from the end-stop, and, in response, may modify a signal to a valve assembly controlling flow of hydraulic fluid to and from the hydraulic actuator. Further, the controller may receive information indicative of the piston reaching a second position at a second threshold distance closer to the end-stop of the hydraulic actuator, and, in response, the controller may further modify the signal to the valve assembly so as to apply a force on the piston in a away from the end-stop.Type: GrantFiled: December 9, 2016Date of Patent: February 4, 2020Assignee: Boston Dynamics, Inc.Inventors: Alexander Douglas Perkins, Kevin Blankespoor, Alfred Anthony Rizzi

Patent number: 10434651Abstract: A control system of a robotic device may receive sensor data indicating at least one deviation from a nominal operating parameter of the robotic device, where the robotic device includes articulable legs that include respective actuators, and where one or more strokes of the actuators cause the articulable legs to articulate. Based on the received sensor data, the control system may determine that the at least one deviation exceeds a pre-determined threshold. In response to determining that the at least one deviation exceeds the pre-determined threshold, the control system may provide instructions for centering the one or more strokes at approximately a mid-point of extension of the actuators, and reducing a stroke length of the one or more strokes of the actuators.Type: GrantFiled: January 13, 2018Date of Patent: October 8, 2019Assignee: Boston Dynamics, Inc.Inventors: Kevin Blankespoor, Alexander Douglas Perkins
