The document summarizes a personal utility vehicle (PUV) project. The PUV is a 3-wheeled, battery-powered electric vehicle based on the Segway design. It uses lead-acid batteries to power two DC motors connected to the rear wheels. Speed is controlled through a DC motor control drive and mechanical braking system. The PUV is designed to be a clean, economical personal transportation alternative with advantages of zero emissions and reduced fatigue compared to walking. Some disadvantages are its lower speed, weight, and ground clearance.

2. Personal utility vehicle is a three wheeled, battery
powered, electric vehicle.
It is based on the idea of a Segway.
The name segway is derived from the Italian word segue
meaning smooth transition.
It can also be referred as a personal transporter.
It is one of the leaders in personal and green
transportation.
The device is technologically advanced and easy to use ,
and when controlled in the correct manner.
Introduction:

3.  Fuel prices have risen, pollution levels are increasing
day by day ,there is a greater awareness of the
damage caused by carbon dioxide and other green
house gases.
The personal utility vehicle helps in reducing
pollution by cutting down oil usage and by using the
existing energy sources efficiently.
They do not produce any emission during the
operation.
Problem Definition:

4. • Batteries – Lead acid batteries (12V or 24V depending
on the power required for the motors).
• Motors – 12V or 24V DC motors.
• 3 wheels.
• Handle for manoeuvring the vehicle.
• Rim braking system.
• Wooden board for assembly and support.
• DC motor control drive.

are welded together in the form of T.

12. PUV runs on 3 wheels.
The motors run using 12V or 24V rechargeable lead-
acid batteries.
The motor speed is set by the DC motor control drive.
The motors are directly connected to the rear wheels.
Speed is controlled using mechanical braking system.
It is a rear wheel driven vehicle.
The directions are controlled using a handle.
Working:

13. A clean, green, eco-friendly machine(zero emission).
Low operating costs.
Very economical when compared to Segway.
More work can be done by using the product vs
walking.
Reduces fatigue caused by walking.
Advantages:

14. Slow having a maximum speed of 12.5mph.
Does not exactly say how far the segway will go with
riders of different masses.
Heavy weighing around 100lbs.
Unlike bicycles, a drained segway cannot be pedalled
home.
Expensive.
Ground clearance is less.
Disadvantages:
