Abstract: Holonomic bases, and drive shafts and roller assemblies that can be used in the holonomic bases. In some implementations, a holonomic base includes at least two pairs of roller assemblies, with each of the pairs being coupled to a corresponding drive shaft. In some of those implementations, each of the roller assemblies of each pair includes three roller segments that are each coupled to the corresponding drive shaft and that each include an exposed outward facing spherical zone that approximates a portion of the surface of a sphere. The roller segments of each roller assembly are in fixed relation to one another relative to the rotational axis of a drive shaft to which the roller assembly is coupled, but the roller segments each freely rotate about a corresponding roller segment rotational axis that extends outward from the drive shaft.

Abstract: Provided herein is a robotic gripper comprising two gripping components, where each component may comprise a rotatable axle oriented along a longitudinal axis, and where the respective axles may be oriented substantially perpendicular to each other. Each component may further comprise a pair of opposing gripping fingers with each gripping finger of the pair being coupled to a respective end of the axle. Each axle may be independently operable to rotate the respective pair of gripping fingers about the longitudinal axis of the respective axle, and each pair of gripping fingers may be independently operable to move the gripping fingers of the respective pair toward and away from each other. A control system for the robotic gripper may thus actuate one or both pairs of gripping fingers to grasp one or more objects.

Abstract: An example robotic chassis may include a frame including a first side member and a second side member connected by a transverse member near respective first ends of first side member and the second side member. The robotic chassis may also include a rigid case having a mounting point for a tablet computer. The rigid case may be rotatably coupled between the side members near respective second ends of the side members. The robotic chassis may further include a first arm and a second arm having respective distal ends and respective proximal ends. Respective proximal ends of the first arm and the second arm may be rotatably coupled to the frame near opposite respective first ends of the first side member and the second side member. In addition, the robotic chassis may include a plurality of wheels rotatably coupled to the frame.
