# Problem
Today, both the primary and secondary industries need to carry out technology-led industrial upgrading, in such a process, how to efficiently detect the work flow is a major problem. For example, in the fields of agricultural inspection, power line and infrastructure inspection, environmental protection and wildlife monitoring, an effective, high-speed and wide-ranging inspection method will increase the productivity and accuracy of related industries.

# Solution Overview
The solution we give is to develop an eVTOL drone that can meet a certain load bearing, set up corresponding communication modules and cameras for it, and transmit real-time data back to the data cloud we build on the server, so as to achieve a large range and long distance accurate detection.

# Solution Components
## Foam Board Body
The foam plate body provides lower weight, thus reducing energy consumption and ensuring adequate performance in terms of movement and acceleration, while it has good insulation, which can effectively reduce heat transfer and noise diffusion. During the engineering phase, its characteristics made the air frame easy to process and had good impact protection characteristics. At the same time, foam board is also a more economical and environmentally friendly approach.

## Power System
Internal micro controller for A/D conversion and initial signal processing ( Atmel atmega328
SIM Card Service )
Use SIM cards to provide identity authentication and data transmission in drone and cloud communications. SIM card technology allows drones to connect to a specific cellular network operator and use its network infrastructure to communicate remotely. In this way, the drone is not limited by distance, is able to perform long-distance missions, and can upload data to the cloud in real time. At the same time, it also ensures continuous connectivity between the drone and the cloud, and the drone can maintain a continuous network connection in the covered area. This allows for prolonged monitoring or data acquisition activities while enabling near real-time data analysis and decision support.

## Camera
Cameras rely on built-in image sensors, such as CMOS or CCD, to convert light into electronic signals. These sensors divide the screen into pixel points, each point can record color and brightness information, analog cameras will capture the image into analog signal output; The digital camera further converts the analog signal to A digital signal through an A/D (analog-to-digital) converter. By reducing its size through encoding and compression algorithms (such as H.264, H.265) to reduce the bandwidth requirements during transmission, the compressed video data can be transmitted through the SIM's cellular network and stored in the cloud.

# Criterion for Success
Our aircraft must be able to lift more than 2kg and maintain smooth horizontal and vertical flight, while our cloud needs to be stable and receive video information from drones flying on the road

Assistive Chessboard

Featured Project

Problem: It can be difficult for a new player to learn chess, especially if they have no one to play with. They would have to resort to online guides which can be distracting when playing with a real board. If they have no one to play with, they would again have to resort to online games which just don't have the same feel as real boards.

Proposal: We plan to create an assistive chess board. The board will have the following features:

-The board will be able to suggest a move by lighting up the square of the move-to space and square under the piece to move.

-The board will light up valid moves when a piece is picked up and flash the placed square if it is invalid.

-We will include a chess clock for timed play with stop buttons for players to signal the end of their turn.

-The player(s) will be able to select different standard time set-ups and preferences for the help displayed by the board.

Implementation Details: The board lights will be an RGB LED under each square of the board. Each chess piece will have a magnetic base which can be detected by a magnetic field sensor under each square. Each piece will have a different strength magnet inside it to ID which piece is what (ie. 6 different magnet sizes for the 6 different types of pieces). Black and white pieces will be distinguished by the polarity of the magnets. The strength and polarity will be read by the same magnetic field sensor under each square. The lights will have different colors for the different piece that it is representing as well as for different signals (ie. An invalid move will flash red).

The chess clock will consist of a 7-segment display in the form of (h:mm:ss) and there will be 2 stop buttons, one for each side, to signal when a player’s turn is over. A third button will be featured near the clock to act as a reset button. The combination of the two stop switches and reset button will be used to select the time mode for the clock. Each side of the board will also have a two toggle-able buttons or switches to control whether move help or suggested moves should be enabled on that side of the board. The state of the decision will be shown by a lit or unlit LED light near the relevant switch.
