The right robotic arm End tool (EOAT) improves flexibility and cost effectiveness by working in coordination with the robot, increasing productivity, improving quality, and reducing costs. In turn, design the EOAT before selecting the robot. One of the major support problems Vaccon helps clients solve is that EOAT is too big for robots. Often you buy robots and design EOAT, only to find that the EOAT is too heavy for the robot to handle.
