# Problem
Given a starting point, destination, path, and environmental factors such as wind speed or water current, a boat can travel both autonomously or remotely.

Specifically, as stated by the project pitch, the goal is to improve the performance achieved by an earlier iteration of this project, as well as demonstrating new capabilities.

We aim to be able to seamlessly switch between autonomous control and remote user control. We also aim to introduce ease of life features like battery indicators, simpler charging / batteries, and an autonomous return to user mode.

# Solution
Our end goal is to make sure we have a boat that autonomously or remotely is able to traverse a body of water regardless of the water’s conditions. By meeting our criterions for success, we believe that we will succeed in creating such a boat.

# Solution Components
_Note: Many of these components, besides the speed sensor and ultrawideband, are already incorporated in the Spring 2022 design of the boat. As discussed with Professor Fliflet, these will be provided as is, and will be utilized with our improvements and changes_

## Subsystem 1 - The Boat
The boat itself is built, with controllable rudders and sail trim. These elements operate the boat, changing its direction and speed as it picks up wind.

## Subsystem 2 - Compass Sensor (LSM303)
The compass works to direct the boat along its path. If it needs to travel north, this data can be taken in and be processed along with the wind direction to direct the boat. The compass also works to detect heeling, which is necessary for telling its current orientation on the water (i.e. if it is impacted by waves).

## Subsystem 3 - Wind Direction Sensor (RotaryEncoder library)
Similarly to the compass, this information is crucial to determine the sail and rudder positions, as there is an optimal orientation for the desired direction with a given wind direction.

## Subsystem 4 - GPS (NEO-6M GPS)
Locates the current position of the boat, and can be verified for current and targeted path, as well as data for testing accuracy.

## Subsystem 5 - Remote Control (FlySky FS-i6 Remote)
Remote control for operating the boat at a distance.

## Subsystem 6 - Speed Sensor
A new speed sensor can be added to the boat to help calculate its current and future position, potentially allowing for some predictability in its movement that could increase accuracy.

## Subsystem 7 - Ultra Wideband Chip (DWM1001)
To return back to a user, an ultrawideband chip could be used to determine where the boat is in relation to the user (located at the base station), and direct the boat back towards them. This can be combined with other data like compass data to determine the direction needed to travel.


# Criterion For Success
Our main criterion for measuring success is making sure that the boat is able to autonomously travel in a straight line adjusting for the wind, water current and speed and other criteria. In the prior project, there hasn't been enough testing conducted, which is one of our biggest goals.

Regular testing in an outdoor environment, preferably in differing weather conditions, to prove the versatility of the boat and the autonomous code would be necessary. We will do this to test the sensors to verify if they maintain the boat’s linear and autonomous motion.

Working with Professor Fliflet to make sure we are starting from the right point with the project, not doing any work that has already been completed, and making efficient use of our time on improvements.

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.
