摘要： 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.

摘要： A motion base comprises lower and upper plates, a plurality of lateral stabilizers coupled in-between and connected to the lower and upper plates, a plurality of actuators, and one or more associated active controllers. Actuators typically comprise a body operatively connected to the upper plate and the lower plate, a rod movably disposed at least partially within the body, where the rod and body define an actuator effective length; and a controllable rod extender configured to selectively extend the rod out from and retract the rod into the body. After determining a desired parameter such as length and an actual parameter such as length, velocity, acceleration, impulse, force, or the like, or a combination thereof for each of the plurality of actuators, a control signal is sent to each controllable rod extender as needed to change the current effective state of that parameter of each actuator by moving each such actuator's extendable rod into or out from each such actuator's body such that the current parameter for each of the plurality of actuators matches the desired parameter for that actuator.
