Abstract:
The goal of project is to design an unmanned ground vehicle (UGV) that can navigate and adapt to its surroundings. Unmanned vehicles will have many important roles in the upcoming future. The importance of these vehicles is that they can be used in many areas such as search and rescue, exploration, surveillance, and for military use. These vehicles are able to navigate in the dynamic environment we live in. An ideal UGV could adapt to its surroundings and learn new capabilities. The UGV’s are usually able to avoid potentially harmful situations, adapt to new surroundings, and ideally, operate independently of human control.
It is a fully autonomous system which is a viable and helpful for demining at low cost. The proposed approach is comprised of following steps; Firstly, it includes designing of a motor control system for four wheel drive using H-Bridges that gives the capability of moving and rotating the vehicle through 360o. Secondly, designing the Infra-Red based transmitter and receiver circuit which has the ability to detect three sides ‘obstacles. Thirdly, it includes a viable algorithm to allow a UGV to avoid a moving obstacle as a path planning system. Fourthly, a reliable wireless video transmission is implemented by Frequency modulated video transmitter. It helps in surveillance purposes. Finally, a mine detection method is achieved by designing a highly sensitive, robust and efficient metal detector. This allows the accuracy of detection and exact location of mines.
