Abstract
Adhesion devices for transport assemblies are configured to engage non-metallic surfaces. The transport assemblies can be wheels, such as omni-directional wheels, or can be a tractor tread assembly. The transport assembly is configured to move adjacent to a non-metallic surface of a structure. The transport assembly comprises an outer surface disposed adjacent to the non-metallic surface as the transport assembly moves, and a plurality of adhesion devices are each mounted to the outer surface and extend at least in a normal direction away from the outer surface. Each adhesion device is responsive to proximity to the non-metallic surface to adhere to the non-metallic surface. The adhesion devices in one or more embodiments include a Van der Waals-type adhesion device, a micro spine-type adhesion device, a suction cup-type adhesion device, or a combination of such devices.
