The contribution of this autonomous amphibious vehicle (UTAR-AAV) includes the determination of vehicular requirements to serve its purpose of being a support and rescue unit on land and water with low turning radius and narrow space navigation ability. The vehicle is electrically powered and uses only a single mechanical drive system, i.e. the direct differential drive. The drive system features a zero-radius steering capability to facilitate maneuvering over both land and water. This reduces vehicle dead weight, bulkiness and simplifies controller design. The automated guided system is placed within the compact body of the vehicle. The vehicle can switch to autonomous mode as required when in the confined or narrow areas. The autonomous mode will activate automatically during communication link cut off. This paper presents the design and fabrication works for the UTAR-AAV.
The compact design of the UTAR-AA V is an attractive solution to the problem of big size amphibious vehicle available in the market. Most amphibious vehicles aim to navigate in a wide and open area. This paper sets out the design considerations for the development of the compact UTAR-AA V. The body and buoyancy design is made compact to pass through narrow and confined area. Differential drive made zero turning radius possible; this will allow the UTAR-AA V to turn in tunnel, in between tree trunk, and rocks. The design allows the UTAR-AAV to perform rescue mission to allocate victims who trap in a disaster area with aid of sensor and Compact Real-time Control System (UTAR-CRCS) using FPGA system implement.Keywords-Autonomous Amphibious Vehicle (AA V), compact design, search and rescue support mission
