This paper presents to develop a system of wireless power transfer for medical applications.Many surgeons use the bipolar electrosurgery system that runs on a battery for a different kind of surgery. This venture is intended to control a rechargeable cordless remote which is used in operation room/theatre. This venture is framed out from Alternating Current(AC) of 220 Volt(V) 50 Hz to 12V Direct Current(DC)  then converted to 12V AC at 20 kHz  in the circuit. DC battery is provided in an electrode of the 12 V bipolar electrosurgery system and the arrangement for charging battery is also prudently/properly made. The new design is an improvement based on specialists' complain regarding the visibility of wire/eletrical line of standard electrocautery instrument Theose wire always put them at risk of being  tangled on the searing instrument which can burn the hand. Not only that, it also restrict their hands movement from performing surgery. The electrical wire is a weakness/disadvantage as it requires an observation of eletrical wire from the hand position to guarantee that it stays sterile amid surgical operations.

This chapter focuses on mid-range wireless power transfer (WPT) systems applied to electric vehicle (EV) battery chargers. The WPT is recently considered as an efficient electric energy transfer process between two or more points in space, without wiring. The technology associated with each specific process of WPT differs from case to case depending on the distance between those points and the power to be transferred between them. The widely adopted distance categories are named short-range, mid-range, and long-range. The short-range is normally defined as up to a few millimeters range. The mid-range is between a few millimeters and a few meters. The long-range distance is defined as a longer than that of the previous category, stretching up to a few kilometers.

The energy capacity of the batteries used as the main power source in mobile robotic devices determines the autonomous operation of the robot. To plan the execution of tasks by a group of robotic tools in terms of time consumption, it is important to take into account the time during which the battery of each individual robot is charged. When using wireless power transfer, this time depends on the efficiency of the power transfer system, on the power of the transferring part of the system, as well as on the level of charge required to recharge. In this paper, we propose a method for estimating the time of transfer of energy resources between two robots, taking into account these parameters. The proposed method takes into account the application of the algorithm for the final positioning of robots, the assessment of linear offsets between robots, includes the calculation of efficiency, as well as the determination of the battery charge time, taking into account the parameters obtained at the previous stages of the method. The final positioning algorithm for robots uses algorithms for processing data from a robot vision system to search for fiducial markers and determine their spatial characteristics to ensure the final positioning of mobile robotic platforms. These characteristics are also used to determine the linear offsets between robots, on which the efficiency of energy transfer depends. To determine it, the method uses a mathematical model of the energy characteristics of the wireless power transfer system and the obtained linear offsets. At the last stage of the method, the time for charging the battery of the mobile robot is calculated, taking into account the data from the previous stages. Application of the proposed method to simulate the positioning of robots in a certain set of points in the working space will reduce the time spent on charging the robot battery when using wireless power transfer. As a result of the simulation, it was determined that the transfer of energy resources between robots took place with an efficiency in the range from 58.11% to 68.22%, and out of 14 positioning points, 3 were identified with the shortest energy transfer time.
