“…UGV can be an autonomous vehicle which is capable to sense their environment on its own or can either be remote-guided vehicle [1]. UGV is widely use in military and industry purposes to facilitate human task especially in surveillance issues [2]. An autonomous UGV must be able to reach its predetermined target position with free collision avoidance path planning.…”

There are numerous numbers of methods that have been introduced to the Unmanned Ground Vehicle (UGV) to find its optimal path. The purpose of this paper is to navigate a cost effective UGV known as MG-TruckS with optimal path planning in an outdoor environment. A Modified Virtual Semi Circle approach is proposed based on situated-activity paradigm. This approach is divided into two phase to compute a free collision path planning; detection and avoidance phase. Implementation of five ultrasonic range finder sensors with a very small blind zone created on purpose and the formation of three layers of influence zone shows the optimized path planning without making any unnecessary obstacle avoidance being computed.
