Industrial robots should be implemented with proper path planning to generate a trajectory which ensures obstacle avoidance and collision free movement. Selection of a path planning techniques need to be done only after detailed studies. This paper deals with the study and implementation of a path planning technique using potential fi eld method for a 2R robot in a given workspace with obstacles. The results are compared with Open Motion Planning Library (OMPL)which uses sampling based path planning algorithms in a similar context. It is found that in higher dimensionality spaces sampling algorithms are more useful and potential fi eld methods are handy in real time applications.
