Looking for a better robot: visual robot control for cheap, flexible assembly

Robots are currently used in many industrial applications since they offer numerous advantages oversimpler forms of mechanisation and human labour. However their use is by no means as widespread as was envisaged when industrial robots first became available. This paper first highlights the problems which are typically encountered when robotic automation is introduced. Following this an approach based on the use of a computer vision system is outlined. This helps alleviate many of the problems including the prohibitive cost of many robot solutions. Advances in hardware and software technology in recent years which have made this possible are described. The potential of the proposed approach has been proven using a cheaply constructed robot mechanism and computer vision system which is able to perform operations central to the production of printed circuit boards (PCBs). The techniques used for successful implementation are highlighted along with improvements which could be made. Consideration for the suitability of the approach to other robotic applications is given.
