The robotic maintenance vehicle (RMV) has a propulsion system, a control system, an electrical power source, a maintenance module, a multi-axis robot, an optical system, and a location translator. The maintenance module is configured to hold different kinds of road maintenance materials. The multi-axis robot is configured to convey the road maintenance material from either the maintenance module to the road, the road to the maintenance module, or both. The optical system and the location translator are configured to be controlled by the control system and operate in conjunction to instruct the multi-axis robot where to pick up and/or place the road maintenance material. The multi-axis robot is configured to be selectively coupled to a distal arm tool.

A trailer includes a first power equipment having an equipment battery pack, a charging device having a primary battery pack, and a docking station electrically connected to the primary battery pack. When the first power equipment is positioned in the docking station, the docking station supplies power from the primary battery pack to the equipment battery pack to recharge the equipment battery pack.

A mobile apparatus for handling a traction battery (100) of an electric vehicle is provided. The mobile apparatus may have a crane (109) for moving the traction battery (100). The apparatus includes a structure (101) of a truck or a trailer. A system (102, 103, 105, 107) for handling and/or analyzing the traction battery (100) is arranged in the interior of the structure (101).

This present invention relates to a vehicle cargo area or bed cover that forms an enclosed space for use in the vehicle bed. The cover is easy to install and remove for a single person and includes a series of lightweight panels, held together by framing elements and installed on the side rails of the truck bed. The lightweight panels are attached at the top to form the top panel. A rear panel is installed on top of the rear wall of the truck bed and an aerodynamic portion is positioned on the top of the cabin of the vehicle. The enclosure can be accessed by opening a door positioned on the tailgate or front end of the truck bed. The enclosure has LED lights for illumination and fans and windows for ventilation.
