Automatic guided vehicle

Detection systems for identifying an object in the path of a vehicle are affected by external interferences which render them unreliable. An oscillating scanner arrangement having first and second spaced apart transceiver assemblies is mounted on a frame of the work vehicle at spaced apart locations and are each pivotally movable between spaced apart angular positions. First and second devices pivotally connect the first and second transceiver assemblies respectively to the frame, and a power device reciprocally moves the first transceiver assembly between the first and second positions. A tie arrangement connects the first transceiver assembly to the second transceiver assembly and reciprocally moves the second transceiver assembly between the third and fourth positions. Thus, the problems related to external interference are solved in an efficient and economical manner. The oscillating scanner arrangement is particularly suited for use on a material handling vehicle.
