Patent number: 10800049Abstract: A method of maneuvering a robot includes driving the robot across a surface and turning the robot by shifting a center of mass of the robot toward a turn direction, thereby leaning the robot into the turning direction. 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 leg prismatically coupled to the inverted pendulum body, and a drive wheel rotatably coupled to the at least one leg. The inverted pendulum body has first and second end portions and defines a forward drive direction. The method also includes turning the robot by at least one of moving the counter-balance body relative to the inverted pendulum body or altering a height of the at least one leg with respect to the surface.Type: GrantFiled: February 22, 2018Date of Patent: October 13, 2020Assignee: Boston Dynamics, Inc.Inventors: Neil Neville, Shervin Talebinejad

Patent number: 10780578Abstract: A method of operating a robot includes driving a robot to approach a reach point, extending a manipulator arm forward of the reach point, and maintaining a drive wheel and a center of mass of the robot rearward of the reach point by moving a counter-balance body relative to an inverted pendulum body while extending the manipulator arm forward of the reach point. The robot includes the inverted pendulum body, the counter-balance body deposed on the inverted pendulum body, the manipulator arm connected to the inverted pendulum body, at least one leg having a first end prismatically coupled to the inverted pendulum body, and the drive wheel rotatably coupled to a second end of the at least one leg.Type: GrantFiled: February 22, 2018Date of Patent: September 22, 2020Assignee: Boston Dynamics, Inc.Inventors: Kevin Blankespoor, John Aaron Saunders, Steven D. Potter, Vadim Chernyak, Shervin Talebinejad

Patent number: 9833899Abstract: An example implementation includes determining a force allocation for at least one foot of a legged robotic device, where the legged robotic device includes two feet coupled to two legs extending from a body of the legged robotic device. The implementation also includes determining a change in mass distribution of the legged robotic device, and based on the determined change in mass distribution, determining a force and a torque on the body of the legged robotic device with respect to a ground surface. The implementation also includes updating the determined force allocation for the at least one foot of the two feet based on the determined force and torque. The implementation also includes causing the at least one foot to act on the ground surface based on the updated force allocation.Type: GrantFiled: April 2, 2015Date of Patent: December 5, 2017Assignee: Boston Dynamics, Inc.Inventors: Kevin Blankespoor, Alexander Douglas Perkins, Marco da Silva, Shervin Talebinejad

Patent number: 9662791Abstract: Example systems and methods for self-righting a robotic device are provided. An example method may include determining an orientation of a bottom surface of a legged robotic device with respect to a ground surface. The method may also include determining that the robotic device is in an unstable position, based on the determined orientation. The method may also include performing a first action configured to return the robotic device to a stable position. The method may also include performing a first action configured to return the legged robotic device to the stable position. The method may also include performing a second action configured to return the legged robotic device to the stable position, if the legged robotic device is in the unstable position after the first action.Type: GrantFiled: January 29, 2016Date of Patent: May 30, 2017Assignee: Google Inc.Inventors: Alexander Douglas Perkins, Matthew Malchano, Shervin Talebinejad

Patent number: 6484068Abstract: A robot apparatus that is able to perform jumping. In a leg structure 110 of the robot apparatus, connecting bars 113, 114 and pivots 112a to 112d constitute a four-point link mechanism. A rod 117 is inserted into an opening formed in the distal end of a leg part 116. A coil spring 118 as an elastic member is provided between one end of the rod 117 and the distal end of the leg part 116. A bar member 120 is connected and secured to a preset point of a connecting member 115 as a knee joint. The coil spring 118 is extended/contracted by the stretching/contraction of the connecting member 115. By the operation of the four-point link mechanism, the trajectory of the distal end of the leg part is linear. The coil spring 118 is mounted at a position such that the distance between a driving shaft 101 and the distal end of the bar member 120 has a substantially linear relationship with respect to the force virtually operating between a driving shaft 101 and the distal end of the bar member 120.Type: GrantFiled: September 21, 2001Date of Patent: November 19, 2002Assignees: Sony Corporation, Boston Dynamics IncInventors: Takashi Yamamoto, Martin de Lasa, Shervin Talebinejad, Darrin Jewell, Robert Playter, Marc Raibert
