Abstract

Unmanned All-Terrain Vehicle (UA V) is remotely piloted or self-piloted vehicle that can carry cameras, sensors, communications equipment or other payloads. The main requirement for UAV emerges from the opportunity to do the dirty, dangerous and dull jobs. Removing the pilot provides the UA V platform designer additional freedom in terms of manoeuvre performance, size, payload and endurance constraints when compared with manned vehicle. For the all-terrain of non-man sized passable sewages or heating, ventilation and air conditioning (HV AC) duct, i.e. pipes with a diameter less than 80cm, wheeled, one-link vehicles are used. They are remote controlled via cable, which has to be dragged by the vehicle itself. Human were used to check the sewage systems but only limited to the man-sized passable sewages. The usage of human inspection is time consuming and expensive. In search and rescue purposes, the UAV can be used to moves .in the highly hazardous area for searching activities. The proposed UA Vis a mobile all-terrain crawler and is designed for navigation in the area that cannot reach by peoples. Its case design, consisting of four rubber wheels that powered by electric drive motor, allows for simultaneously climbing a step and turning, e.g., at a junction consisting of a 600 millimetre pipe and a branching 300 millimetre pipe with equal top levels. The cable will linked to the robot to supply the energy to provide the power for its motors, the sensors, video stream and the electronics, including an industry standard PC/I 04+ computer system and seven micro controllers, allowing for a non-stop operation. In this research, Unmanned All-Terrain Vehicle will be design and developed.The structure of the UA V is tested with universal testing machine (UTM) for static test.The test included tension, compression, flexure and shear testing. The UA V is tested based on the reliability and toughness to withstand all the possibility loads. After that the mechanical structure of UA V will be optimised and simulates the finite element analysis using the Cosmos software. Lastly, the results from the testing are compared and developed the solution for the proposed UA V mechanical structure.
