Product Overview
Product Overview
A standard suitcase can be difficult to have with you at all times. You may forget it on the side and leave without it. That is why we created The PursuitCase; a standard sized suitcase that follows you aroundwherever you go so you don’t need to worry about it.
Problem
Problem
Going on vacation can be difficult. The whole family has to bring a suitcase with them, whether young or old. For some, like young children or old grandparents, wheeling around a heavy suitcase can be difficult. That’s why we created The PursuitCase.
How it Works
How it Works
Our projects are mainly focused around a Pixy2 camera and tracking system. This camera tracks the user and sends a signal of where he or she is located relative to the camera straight to a servo motor, which directs the front wheels of the suitcase. We have direct current motors in the rear that propels the suitcase forward. We installed an ultra- sonic distance sensor to prevent collisions with various obstacles including the user himself. All this hardware paired with our algorithm is how we created The PursuitCase.

Who is it For?
Who is it For?
The PursuitCase is designed to be used by all kinds of people wearing a specific color that you can specify. As long as that color is in front of the camera, the suitcase will move towards you. That being said, the ease of use makes this product perfect for anyone of all ages, from a baby taking its first steps and on.
Competition
Competition
As of now, there is only one company that is designing a similar product, Ovis, which follows you via GPS. There are many issues with this. The first issue is that it costs $800 to buy. The PursuitCase can realisticly be sold for more than 75% less than that. Another issue is that Ovis can only follow you if you have a smartphone. The PursuitCase can follow anyone with a colored shirt on his back. A third issue with Ovis is since it uses a smartphone with new technology, it can be difficult for older people to use, which is what The PursuitCase solves.
Future Improvements
Future Improvements
Although The PursuitCase is an innovation ahead of its time, there are still minor bugs that can be fixed. For example, with better color tracking technology at this price point, we can make The PursuitCase work better in poorly lit environments. Furthermore, with advancements in servo-motors, The PursuitCase wouldn't lose track of the object as easily.
