When it comes to vision systems, manufacturers want more cameras for more accuracy. Some have even applied this principle to their robots. For example, several automotive and white goods manufacturers use dual- or single-arm robots equipped with a two-camera vision-guidance system.
The robots are made by Motoman Robotics Div. of Yaskawa America Inc. VisionPro 3D image-processing software, made by Cognex Corp., ensures that the robots accurately locate, pick up and move parts from a pallet onto a conveyor or into a machine for assembly.
