Development of Contact Type Positioning-free Supplier and Charger

Abstract

In near future, many autonomous robots will be used to perform, to help with housework and to take care of the elderly people. However, their power consumption is very high, so it is significant to supply the power to robots efficiently. The three major power supply methods have been used; “wired style”, “internal rechargeable battery” and “change style”. Each method has some advantages and disadvantages. We focused on “change style” but it requires the high-level control to change battery correctly. If we could solve this problem, the robot’s efficiency will become better. In this study, we will show that the electrical current controller using diode-bridge can flow the electrical current only one direction without depending position and the automatic battery charging system can use only putting the battery on it and charge the battery automatically.
