Abstract: The present disclosure concerns a system and associated method for welding a piece. The system includes a 6-axis welding robot including a robotized arm, a vision module and a computing device. The vision module is mounted to a fourth axis of the robotized arm and includes optical sources and a camera. The optical sources are operable to irradiate the piece along irradiation paths. The camera is configured to receive irradiated light from the piece and to generate image data. The computing device is operatively connected to the camera and includes non-transitory computer readable storage medium having stored instructions that, when executed by a processor causes the processor to receive the image data; obtain a reference welding path to be followed by the welding robot for welding the piece; send instructions to the welding robot to weld the piece according to the reference welding path.

Abstract: An off-road dolly has a pneumatic system for providing compressed air to trailer brakes and dolly brakes means for providing synchronized engagement thereof. Off-road dolly also has an electrical circuit providing synchronized engagement of dolly signal lighting system with trailer signal lighting system. Propulsion for off-road dolly and trailer can be provided externally, using a forklift, or by the off-road dolly itself using a motor installed thereon. Synchronized operational engagement of dolly brakes with trailer brakes, and dolly signal lighting system with trailer signal lighting system, can be controlled using a remote control.
