Four wheel Steering is a method developed in automobile industry for the effective turning of the vehicle and to increase the manuverbility. In a typical front wheel steering system the rear wheels do not turn in the direction of the curve and thus curb on the efficiency of the steering. In four wheel steering the rear wheels turn with the front wheels thus increasing the efficiency of the vehicle. The direction of steering the rear wheels relative to the front wheels depends on the operating conditions. At low speed wheel movement is pronounced, so that rear wheels are steered in the opposite direction to that of front wheels. At high speed, when steering adjustments are subtle, the front wheels and the rear wheels turn in the same direction. By changing the direction of the rear wheels there is reduction in turning radius of the vehicle which is efficient in parking, low speed cornering and high speed lane change.

Embedded Systems & Robotics
Embedded Robotics the most popular technology that introduces advanced technologies and solutions for emerging embedded applications, including digital consumer electronics, automotive, wireless/ubiquitous computing and factory automation. Embedded System are ever more capable engineering systems that we all use in our daily lives, ranging from applications in mobile telephones to washing machines, cars to airplanes. This programme brings both fields together to provide multidisciplinary skills with employment potential in a wide range of areas. Embedded systems are used widely over simple robotics because of its advantages and wireless medium transmission. Embedded robotics is a field in which mechanical, software; power is used to run a system
