Patent number: 10611019Abstract: Robotic systems include a frame or body with two or more wheels rotatably mounted on the frame or body and a motor for independently driving each wheel. A system controller generates a signal for actuating each motor based on information provided by one or more sensors in communication with the system controller for generating feedback signals for providing reactive actuation of the motors for generating one or more functions selected from the group consisting of forward motion, backward motion, hopping, climbing, and balancing. A power source is included for providing power to operate the drive motors, system controller and the one or more sensors.Type: GrantFiled: August 4, 2017Date of Patent: April 7, 2020Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Thomas R. Bewley, Christopher M. Schmidt-Wetekam

Patent number: 10189342Abstract: A ball-balancing drive assembly includes a ball having a ball surface and a reference axis extending through a centroid of the ball. Three omniwheel assemblies, each having a motor with a motor axle and an omniwheel configured to rotate around the motor axle are mounted on a chassis configured for supporting the three omniwheel assemblies at radially symmetric spacings with the motor axles oriented at an angle relative to the reference axis and the omniwheels oriented in mutually-orthogonal planes. Each omniwheel frictionally contacts the ball surface to convert rotational motion of the motor axle to torque on the ball.Type: GrantFiled: February 9, 2016Date of Patent: January 29, 2019Assignee: The Regents of the University of CaliforniaInventors: Thomas R. Bewley, Jeffrey M. Friesen, Eric Sihite, Daniel Yang

Patent number: 8083013Abstract: Examples and implementations of various robotic mechanisms, devices, components, systems and techniques are provided, including multimodal robotic devices and systems. For example, a multimodal robot can be configured to autonomously reconfigure between two or more primary modes of operation. Such robots may be used in a wide range of applications, including reconnaissance, exploration, search and rescue, military, sports, personal assistance, education, and entertainment and toys. Described examples of multimodal robots can be wheeled robots that use two or more drive wheels to perform various motions and operations.Type: GrantFiled: December 6, 2007Date of Patent: December 27, 2011Assignee: The Regents of the University of CaliforniaInventors: Thomas R.

Publication number: 20040181365Abstract: A method is provided for identifying the unknown parameters of a non-linear dynamic system model that has one or more system inputs. The governing state equation is derived from the non-linear dynamic system model. An adjoint equation is determined from the governing state equation, and a perturbation cost function is determined, based at least in part on the determined adjoint equation. Changes in the perturbation cost function that result from incremental changes in one or more of the system inputs and from arbitrarily chosen values of one or more of the unknown model parameters are iteratively determined to thereby identify the unknown model parameters.Type: ApplicationFiled: October 29, 2003Publication date: September 16, 2004Inventors: Sharon Liu, Thomas R.
