An endless-track type mobile climbing vehicle containing a suspension apparatus, transducer manipulator and surface cleaning system to perform non-destructive examination of structures while traversing the structure in all positions. The invention is able to conform to large range of irregularities of the climbing surface while maintaining contact between the track and adhering members and uniformly distributing the climbing loads on the adhering members giving the system a high payload to weight ratio. The invention is moves the inspection transducer over the surface while maintaining correct alignment of the tool relative to the surface. The invention allows an operator to perform an inspection on structures that require cleaning or other preparation prior to inspection. The invention allows an operator to perform an inspection remotely.

The invention relates to a welding technical field and provides a crawling welding robot. The crawling welding robot includes a vehicle chassis and two crawler wheels connected to two opposite sides of the vehicle chassis, respectively, wheel carriers of two crawler wheels are movably connected with the vehicle chassis. In this way, when the crawling welding robot moves on a non-planar surface for welding, the two crawler wheels can freely adjust its posture relative to the vehicle chassis to adapt to the surface for welding and improve a degree of fit between the two crawler wheels and the surface for welding, making the moving direction of the crawling welding robot easier to be controlled and reducing a probability of the crawling welding robot slipping or falling from the surface for welding.

Autonomous robotic cleaner (ARC) for cleaning solar panels having an anchoring mechanism including at least one rechargeable power source, at least one cleaning mechanism, a controller and an anchoring mechanism, the cleaning mechanism for cleaning dirt off of a surface of the solar panels, the controller for controlling a cleaning process of the ARC and the anchoring mechanism for magnetically anchoring the ARC to an anchoring surface coupled with a solar panel, the anchoring mechanism including an arm and a drive mechanism, the arm including at least one ferromagnetic end piece and the drive mechanism being coupled with the arm, wherein the drive mechanism moves the arm between a magnetically engaged position with the anchoring surface and a magnetically disengaged position with the anchoring surface.

A tracked climbing vehicle containing a compliant suspension apparatus to prescribe the distribution of forces on the adhering members in the tracked climbing machine. The compliant suspension apparatus is configured to negotiate irregularities in a climbing-surface without the vehicle tracks losing full surface contact and adhesion by distributing the loads from the climbing machine chassis to the adhering traction members in a specific prescribed fashion. The apparatus thus avoids exceeding the allowable force in any adhering traction member and significantly improves the performance of the climbing machine.
