Specialized gripper design is an active area of research where quick retooling enables the robot during the production cycle. Automated palletizing operations may require additional degrees of freedom with more sophisticated drive mechanisms controllers and expert programming features 12 . In GE s Electrical Distribution and Control plant Morristown TN five CG-120 gantry robots C D Robotics palletize a range of product sizes cartons range from 8 X 8 in2 to 12 X 40 . Since 1989 GE s robots have provided versatility over manual and conventional palletizing and eliminated injuries caused by manual lifting 13 . Spray Coating. This is the process of applying paint or a coating agent in thin layers to an object resulting in a smooth finish. Industrial robots are suitable for such applications where a human worker is in constant exposure to hazardous fumes and mist which can cause illness and fire. In addition industrial robots provide a higher level of consistency than the human operator. Continuous-path control is required to emulate the motions of a human worker with flexible multiple programming features for quick changeovers. Hydraulic drives are recommended to minimize electrical spark hazards. Chrysler Corp has found an alternative process to fill the seams on its new LH vehicles to eliminate warping and inconsistent filling. In 1992 a four-robot station Nachi Robotic Systems Inc. at Chrysler s completely retooled plant Ontario Canada successfully replaced the manual filling of the seams with silicon-bronze wire 14 . Assembly. Many products designed for human assembly cannot be assembled automatically by industrial robots. The integration of product design and assembly design belongs to the concept of design for manufacturability 15 . More recent research in design for assembly has been completed at the University of Cincinnati 16 . Design for manufacturability results in the design of factories for robots. Fewer parts complex molding and .
