The wireless power transfer for charging the mobile robot is implemented using inductive coupling method. The system setup consists of transmitter coils whose switching action is controlled through transistors, receiver coil connected to full ridge rectifier and mobile robot. The track consists of number of transmitter coil which transmits power in form of electromagnetic waves. The receivers in the robot, which receives these waves and converts it back to electric power to charge the battery. The robot tracks its target destination based on the user command from the smart phone through Bluetooth. Very few theoretical researches are available on this field. A prototype was developed and tested based on the researches. The system achieves good range but falls short in efficiency to charge a battery, charging of battery takes longer time than regular charging time. Further research and extensive exploration can bring this technology from theory to practice.

INTRODUCTION In the for-seen future it will mostly be driven by the cutting-edge technology of wireless power transmission (WPT). Since it may sound simple to hear that, it removes one item in the list which is wire to transfer the power. But it is quite complicated than it sounds, it uses air as a medium using electromagnetic waves to transfer the power. However, it has the transmitter, receiver coils but which may not have a direct contact with a minimal distance in-between. WPT becomes an added advantage in the situation like in hazardous areas and human inaccessible areas. The key advantage in the wireless power transfer is that its maintenance free which provides the benefit of using this in tough environments like dirt, ice, water and chemicals which does not affect the transmission [1]. As the benefits it has its own disadvantages the power loss is more in this and low distance power transmission only it is effective. Some examples like wireless charging mobile phones, electric tooth brush. It can be introduced in the electric bikes for charging that surely reduces the clutter of wires in the charging [2]–[4]. It is been used in certain technologically developed countries but the installation cost is high. But compared to solar vehicles where the size of the attachment is big, this is not the case in the WPT systems. Developing the circuit for the WPT system is quite difficult since it needs to convert AC-DC to charge the battery [5]–[7]. Khutwad and Gaur [8] has defined the challenges in wireless charging which deviates from traditional concept of charging. Inductive coupling is used in this paper to transfer the power from the transmitting to the receiver coil and the switching is triggered by the metal oxide semiconductor field effect transistor (MOSFET)
