Self-stabilizing platform, carrier, or base

摘要

A two-wheel movable platform, carrier, or base having canted wheels is disclosed. In one embodiment, the two-wheel movable platform, carrier, or base includes adjustable canted wheels in which the angle of the canted wheels is adjustable. In this embodiment, the two-wheel movable platform, carrier, or base includes a pair of wheel assemblies mechanically coupled to a battery housing. Each of the wheel assemblies includes, for example, a mounting plate, a drive motor arranged in a motor housing, a canted wheel that is driven by the drive motor, and an angle-adjusting motor for adjusting the angle of the canted wheel. In another embodiment, the two-wheel movable platform, carrier, or base includes canted wheels that are set at a fixed angle.

主权项

1. A platform, carrier, or base comprising:
a first wheel assembly and a second wheel assembly mechanically coupled to a support unit, wherein the support unit has at least a first side and a second side that are configured to be opposite one another, wherein the first wheel assembly is mechanically coupled to the first side of the support unit and the second wheel assembly is mechanically coupled to the second side of the support unit; wherein each wheel assembly comprises a mounting plate, a drive motor, a motor housing, a wheel, and an angle-adjusting motor; wherein the drive motor is mechanically coupled to the wheel by a drive shaft; the motor housing is moveably coupled to the mounting plate by a first hinge; the angle-adjusting motor is movably coupled to the mounting plate by a second hinge; and wherein the angle-adjusting motor comprises a lead screw and the motor housing comprises a lead screw coupler comprising a receptacle comprising a threaded opening for receiving the lead screw of the angle-adjusting motor; and wherein the angle-adjusting motor can be activated to position each of the two wheels at an angle θ relative to a plane parallel to at least one surface upon which the platform, carrier, or base is placed, wherein the angle θ for each of the two wheels can be the same or different and has a range from about 0 degrees to about 20 degrees.
