28 Wireless Power System for John Deere

John Deere proposed an open-ended project to develop a power system to replace the hydraulics used in power transfer for their vehicles. They want to replace the need for tubing because it can break or cut in extreme applications. This system would potentially see use in heavy machinery such as logging vehicles. They seek a proof of concept for an alternative method of power transfer without the use of wires, preferably with some ball joint to allow motion.

Our proposed solution is to create a power system that utilizes resonant inductive coupling to transfer power wirelessly through a ball joint. This ball joint will be made of magnetic material to aid the magnetic field that will be key in transferring power. At the input and output of the system, we would implement power converters and their respective control systems, connecting them at the ball joint. Further additions can be made to improve the efficiency and functionality of the system, but the basis of the idea is a power system using a ball joint.

Research in wireless power transfer has been relatively recent, and we are now seeing it used in applications such phone and electric car chargers. Both of the examples, however, only utilize inductive charging. In our project, we will attempt to implement resonant inductive coupling to increase the range of operation of the joint. Furthermore, we will need to interface with the mechanical engineering group in order to design the mechanics surrounding the ball joint rather than rely solely on electronics. This project will focus on the unique application of a ball joint and resonant inductive coupling to create a proof of concept for wireless power transfer in relevant applications.

The proposal our group has is of creating a board that will be able to teach students about logic circuits hands on. The project will consist of a board and different pieces that represent gates. The board will be used to plug in the pieces and provide power to the internal circuitry of the pieces. The pieces will have a gate and LEDs inside, which will be used to represent the logic at the different terminals.

By plugging in and combining gates, students will be able to see the actual effect on logic from the different combinations that they make. To add to it, we will add a truth table that can be used to represent inputs and outputs required, for example, for a class project or challenge. The board will be able to read the truth table and determine whether the logic the student has created is correct.

This board can act as a great learning source for students to understand the working of logic circuits. It can be helpful in teaching logic design to students in high schools who are interested in pursuing a degree in Electrical Engineering.

Please comment on whether the project is good enough to be approved, and if there are any suggestions.
