Enhancement of Drive System of Robot through Wireless Energy Transfer

The elimination of batteries in mobile robots attracts considerable attention in the field of robotics. The process of exclusion of batteries brings up economical reduction in cost, weight,recharging time and total working time of the robots. This system finds a way for the continuous operation of a mobile robot. The present study shows a new trend of drive system for autonomous vehicle operating on a continuous energy supplied with no batteries and wires. In this proposed system, the power transmission is actively done through a high power transmitter antenna coil and a receiver coil embedded in the autonomous vehicle. The drive system of the robot receives the energy from the receiver coil which acquires the energy through wireless from the transmitter coil. From the result of received energy, the designed spy robot has operated wide a distance of 100 cm with out any fluctuations. The efficiency of the energy obtained from the transmitter coil is around 60%. The maximum distance that the energy transmitted is up to 240cm with a fall in output voltage. The obtained result is tabulated.
