Hungry vegetarians

Hungry Vegetarians contains vegetarian/vegan restaurants around Singapore, including restaurants with vegetarian/vegan options. The user can then view information about the restaurant nearby their location by clicking on the name. There is a  "Navigate Me" function at the below the description of the restaurant that opens Google Maps with directions to go there.

The "Add to Itinerary" button, beside "Navigate Me", adds the restaurant into a list of places-to-go. On clicking "Plan Itinerary", the app solves a Travelling Salesman problem and gives the user the quickest path to all restaurants. 

fratricide prevention device

25% of casualties in war are due to friendly fire, increasingly so due to advancements in military technology. This device prevents accidental fratricides by stopping the trigger finger using EMS.

A simple detection mechanism was mounted in front of the gun that detects a specific colour; a simple solution because it was not the main focus of the project. 

The hand attachment uses a processor that receives a signal from the detection mechanism, and will then apply current directly into the surface of the skin, at the muscle responsible for lifting the index finger. This action prevents friendly fire by not allowing the user to shoot. However, with conscious effort, the user can still fire his rifle.

Completed in SUTD's Introduction to Design module, this freshmore project was the first in its history to be patented.

This project was featured on Straits Times, Lian He Zao Bao and 95.8FM.

XAVIER SMART door lock

The door lock scans the person's face, verifies with Microsoft Azure through a raspberry pi. Within about 3 to 5 seconds, an arduino uno unlocks the door and the authorized user is granted access.

This project was featured on Channel 5, Channel 8 and Channel News Asia and on TODAY.

binary battle

Using a Mojo FPGA and a similar concept behind Tetris Battle, we created a binary addition battle-style game where the goal is to fill up the opponent's red LED bar, similar to a stack in data configuration terms. 

To do that, each player answers a different set of questions on his side, given 2 4-bit numbers represented as LED and 4 toggle switches to answer the questions.

A player's stack can increase by either answering a question wrongly, or the opponent answering a question correctly.

The loser is defined by allowing his stack to hit 7.

SUTD ORIENTATION NIGHTWALK

Done for SUTD Orientation Nightwalk, pressure-sensitive tiles made of corrugated board surround a room and light up in sequence like a code. When pressed in the correct order, the next sequence speeds up.

The game ends when all sequences are complete or the participants fail to press them correctly. The buttons are controlled by an arduino uno.

Adaptable walking cane

Walking stairs with a cane will require users to compromise posture and support to reach for higher or lower steps. This product features a motorised walking cane that extends and retracts such that the user does not overreach and overextend.

This project was done as a submission for coHack, a hackathon based on helping the needy and disabled. It was awarded the 2nd place.
