The amphibious spherical explorer (ASE) our team is building is mainly for outdoor adventure. The ASE will have no difficulty traveling in water, swamp, dessert, and land due to its spherical shape and pendulum driven principle. Comparing to most robots, ASE will be more versatile since it could travel under most circumstances. As for the other spherical robots, ASE is more adaptable because of its flexible yet enduring shell and at the same time we are aiming to design a better control system to solve the balance issue.

The ASE will be implemented using dual-actuator design consisting of one DC motor and one Servo motor, magnetic encoder, gyroscope, micro-controller, WIFI chip and etc. Specifically, we have decided to build this to be a general-purpose robotic platform as we are planning to leave an I2C bus to interface corresponding interchangeable modules designed for diverse tasks and various usages. The control signal will be sent from PC to the explorer, and the data collected by the task module are transmitted back to the users for debugging. The entire communication process will be accomplished through WIFI.

Our team members have had fair amount of experience in Embedded programming & Control system design, Mechanical CAD, and PCB design which will be efficient through the project building process.

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.
