There are a lot of wires inside mechatronic devices, such as industrial robots. These wires may cause several disadvantages in the processes of design, manufacture, implementation, and maintenance. To be more specific, they may cause motion range limitations, an increase in weight, an increase in production expenses, an increase in assembly/disassembly costs, and the risk of wire breakage. Robots typically has two types of wires: control lines for transmitting control signals and power lines for supplying electric power. There are few studies to realize both of these lines wirelessly at the same time, especially for articulated arm robots. Therefore, we have been conducting research and development on wire-free robots that enable both types of wires to be wireless. We have developed the wire-free robotic system and a prototype model of the wire-free robot without wired connections at each joint. It has control lines made wireless by 60 GHz millimeter wave band wireless communication and power lines made wireless by magnetic resonance wireless power transfer. Using this prototype model, we are verifying its high functionality and practical applications, such as high-speed operation and high-torque control. In this presentation, I will provide an overview of the wire-free robot and report on the study of its high functionality and practical application using the prototype model. |
