A spinning platform will be assembled on the moving robot. A ultrasonic sensor would be mount on top of the platform. The ultrasonic sensor will get the distance between the current robot to the surrounding objects and transfer it's own distance data to an arduino board. The arduino board will convert the data to become the format that a smart phone can process. Then, the processed information would be sent to a smart phone.

Then we want to connect our mapping system to a robotic programming platform called starL.
StarL can use a smartphone paired with a robot(irobot create) using Bluetooth and control it's movement. It is also capable of communication between robots.
After we have a self mapping system connected with starL, we would like to make it distributed, which means a number of robots working together to map some space. We are going to combine the distance information generated from each individual robot. By knowing the start position of every robot, this enables the robots to know the relative position to each other.

This project would require a power source, a circuit that helps control the motor, some sensor data filtering circuit, one motor for the spinning platform, C coding on arduino to process sensor data, java coding on android phone. We may need to add a circuit that helps transfer data from arduino to the phone.

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.
