Electromagnetic manipulation system for nanorobots and microrobots using magnetic field gradients and field strength

Abstract

Use of magnetism as wireless robot control is a promising and potential field in the future. For example, magnetic manipulation of untethered robots is having more applications and critical role in different interventions in the human body. In some applications, straight contact to manipulated target by the human using tool is not preferred. Thus, wireless manipulation is a good choice. Robot control in the dry surface is also potential application. There exists other possibilities for the wireless robot control, but magnetism provides possibilities beyond robotics. So far most of the magnetic field controlling systems are based on robot control in fluids (inside the human body). The human body is overall challenging region to control these robots. Because of different kinds of challenges, there are several characteristics demands to the controlling system. There exists already a couple of different kinds of controlling systems for nanorobots and microrobots. However, none of the systems is optimal for all the characteristics. To optimize all possible characteristics is difficult because not all characteristics depend only on magnetic field controlling systems. A system suitable for different kinds of applications could be developed and that is the focus of this thesis (introduced coil configurations). This system would also be suitable for new applications beyond robotics and could open up new possibilities in the future. Future work would include optimizing system introduced in this thesis.
