Escalator Compatible Wheel Chair

People who use Wheel Chairs , always face difficulty using escalators. Students at Illinois Institute of technology find solution of this problem by designing this chair in different way. Wheel Chair developed by them can be used at escalators.


Building wheel chair requires good design, it should be robust and light weight. Their is very little scope of error because it is going to be used on escalators where even a minor mistake put its rider at risk. In the video given below, you can see how student of Illinois University has implemented this project successfully.

How it works?
It is designed in such a way that when it is used on escalators it becomes immovable and stable. For that purpose it has support in the front which gets grounded when required.

Mini Scooter

Mini Scooter is good and practical project for mechanical students. Moreover, it can be build using the materials which are available easily.

By building scooter , you will understand the how it works and also what are the difficulties engineers face while building two wheeler. I would suggest you to go one step further by building it green. Green means scooter which runs on compress air or solar or any form of energy which is less polluting then existing one.

While building this project , I would suggest you to focus only on its functioning and less on looks or its design malfunctions. Because designing is altogether different field , it needs different approach and time which we can do later after building our mini scooter.

Things to consider:

Estimate cost and a profit feasibility
It should be light Weight
Safe to ride

Components Required:

1. Power
2. Engine
3. Chassis and
4. Controller

This project is based on very simple concepts of mechanics, and it is easier to understand if we start from tail. For example, to rotate a wheel, we need engine, in this case Two Brush-less DC Motors . These motors need to be controlled by controller, in our case, it is two power MOSFETs Rectifier (IRFB3207 and IRFB3077). Moroever, to power these motors, we will need some form of energy and here we use electric power stored in batteries. You can use as many batteries as you want.
