#Problem

In light of national carbon peaking and carbon neutrality goals, along with the rapid development of artificial intelligence, smart electric vehicles as a backbone force in reducing carbon emission and air pollution mitigation showcasing its potential to become a vital component of future vehicle industry. However, one of the largest obstacles in the promotion of electric vehicles (EVs)is the capacity of batteries. A simpler way around this problem is to build a ubiquitous charging system that is robust and efficient. As a result, industries are having intense competition in achieving better engineering design and attracting consumers at the same time.

#Solution Overview

Our solution is to design and develop an efficient, autonomous wireless vehicle charging system that utilizes advanced resonance tank control and output voltage regulation. The focus is on optimizing wireless power transfer through precise coil positioning and adjusting the control of the resonance tank to maintain stable power output. Additionally, the project seeks to create a control system that enables a vehicle to navigate autonomously to a charging station, aligning itself correctly for wireless charging without human assistance. The proposal also aims to develop a complete, integrated prototype consisting of the vehicle, PCB, charging base, and control software to demonstrate autonomous routing and charging in a real-world environment.


#Solution Components

##Vehicle movement control algorithm -The movement is fully controllable as demanded by the program -The algorithm enables the vehicle to scan across accessible areas and calculate a route around walls for the vehicle to follow. -As the routing program is running, the car is automatically finding its way to the station.

##A wireless charging system between the vehicle and the charging station -Two PCB boards are applied to form a CLLC charging system. The value of the capacitors and the inductors are adjusted to comply with charging needs. -Control signal is designed to drive the wireless charging system.

##A physical vehicle -The vehicle is designed so as to carry the micro processors and wireless charging receiver. -The vehicle is physically optimized to ensure a better efficiency of the wireless charging. -The vehicle is capable of smoothing bumps on the road.


#Criteria of Success

An autonomous car with energy storage and fast speed.
The wireless charging power Pin≄20W.
Car can automatically align to the charging coils.
Car can detect the place of wireless charging station.
Obstacles can be avoided during the driving.

An Engineering Solution to Auto Chess Set

Featured Project

# Problem

We are magic engineers. We found the Muggle world too boring! The wizard chess in *Harry Potter* where players move their pieces by vocal command, pieces move and attacks with cool sound effects, and pieces explode when they die must be a lot more fun! Those interesting properties have made wizard chess a favorite among fans of *Harry Potter* in the muggle world. *Harry Potter* fans and chess lovers would like to have a wizard chess set for its collection value and to bring a wonderful experience playing chess.

# Solution Overview

We will implement a chess set analog to the *Wizard's Chess* in *Harry Potter*, where chess pieces are controlled by voice and can move by themselves. Our system consist of an electronic controller, chess pieces and a chessboard with mechanics to move chesspieces.

# Solution Components

## Chessboard and pieces

Our system contains a two-axis Cartesian robot hidden inside the chessboard. It picks up chess pieces with a magnet to move them around. It will move away any blocking pieces when making a move and put them back later.

## Voice input

The voice input consists of an microphone. It accepts voice signals from players and send it to the control.

## Control

We control the mechannical system, track game states and process voice signals with a Raspberry Pi board. The board will be connected to Baidu Cloud voice service to process voice signal. It interprets voice input to generate player moves or use algorithms to make moves. Then it generate signals to control the robot system to move pieces.

# Criterion for Success

Our product should be able to complete chess games repeatedly with 0, 1 or 2 players without the need to move pieces manually. The system accept and interpret vocal commands correctly. The robot can accurately approach a piece and move it to desired location according to the command. It should move other pieces away to make path for a move.
