Abstract: A two-wheeled vehicle is provided. The two-wheeled vehicle includes a chassis having a height, a length and a width, in a first wheel rotatably connected to the chassis, the first wheel having a perimeter, a diameter and a geometric center, and the diameter of the first wheel being at least 75% of the height of the chassis, a motor for providing a drive energy to the first wheel, an axle rotated by the motor, a drive gear connected with the axle such that the drive gear rotates with a rotation of the axle, and a plurality of teeth disposed about the first wheel and mechanically engaged with the drive gear at a location closer to the perimeter of the first wheel than to the geometric center of the first wheel.

Abstract: A two-wheeled vehicle is provided. The two-wheeled vehicle includes a chassis having a height, a length, a width, a front and a back, a first wheel rotatably connected to the chassis, the first wheel having a perimeter, a diameter and a geometric center, and the diameter of the first wheel being at least 75% of the height of the chassis, a second wheel rotatably connected to the chassis, the second wheel having a perimeter, a diameter and a geometric center, and the diameter of the second wheel being at least 75% of the height of the chassis, and a counterweight coupled to the chassis such that the counterweight can adjust an orientation of the chassis in response to a change in pitch of the chassis about an axis passing through the geometric centers of the first and second wheels.

Abstract: A motion assembly that produces pitch and roll motions includes lower and upper plates. A pivotable coupling having upper and lower shafts extending from its center is coupled between the upper and lower plates. At least two linear actuators are coupled between the plates. Extension and retraction of the actuators pivots the upper plate about the pivotable coupling relative to the lower plate. A vehicle includes two steerable propulsion wheels coupled to a chassis. A lower plate of a pitch and roll assembly, similar to that just described, couples to the chassis via a slew bearing. Seating is coupled to the upper plate. The seating rotates with respect to the chassis via controlled rotation of the slew bearing with reference to the chassis. The seating can be rotated to point in any direction with respect to the chassis regardless of the direction the steerable propulsion wheels move the chassis.
