The document discusses Mecanum wheels, which allow vehicles to move in any direction. Mecanum wheels consist of a hub with rollers oriented at 45 degrees that enable forward, backward, side-to-side, and rotational movement. They have applications in industrial vehicles for tight spaces. Mecanum wheels provide omnidirectional movement, high load capacity, and easy control but can reduce efficiency and require more complex designs than typical wheels.

3. INTRODUCTION 3
The Mecanum wheel is a design for a wheel which can move a vehicle in
any direction.
It can be used in tight spaces for easy travelling
It is sometimes called the Ilon wheel

4. 4
Idea brought by, Bengt Erland Ilon, who came up
with the idea when he was an engineer with the
Swedish company Mecanum.

5. 5HOW DO MECANUM WHEELS WOKS ?
Mecanum wheels, also known as omini wheels or ilon
wheels.
Consist of a hub with rollers oriented 45° to the axis of
rotation.
They enable conventional forward & backward movement
as well as side to side and even rotation
To accomplish this, each wheels turn independently

7. WHEEL PLATE 7
The Wheel plate design was manufactured by
aluminium alloy.
Aluminium alloys were selected to obtain good
weight to strength ratio.

Rubber rollers are typically manufactured using
molding or casting processes.
Each Mecanum wheel has only one roller contact
most of the time
Rollers are placed 45 degree to floor

11. 11DC MOTOR
A DC motor is any of a class of electrical machines that
converts direct current electrical power into mechanical
power.
Motors are used to drive the Mecanum wheels.
There are many different type DC motors that could
be used for dive purpose of the platform.

12. 12DC MOTOR
It requires 36V 350W electric power
Type of motors
Gear motors are mainly used
Brushless motors
Brushed motors
Steppr motor

13. 13BATTERY
The selected motor require a 36V 350Wpower supply that needs to have
sufficient capacity to power the four drive motor for an appropriate
amount of time
Rechargable cell
32Ah capacity
Lead acid / Lithium ion battery
An addition circuit is installed to power
the output voltage

Suspension System used in mecanum wheeled vehicle
Dependent suspension system
Independent Suspension

21. Suspension System
Dependent suspension system
It is called dependent because one side depends on the other:
if one wheel was to lower, the other opposite wheel would rise.

22. Suspension System
Independent Suspension
The advantage with independent suspension is that
each wheel is isolated from the other
The advantage of this system is that the wheel will
stay perpendicular with the floor no matter what
position the swing arm is in.

23. » it can move in all 8 directions i.e., in 360 degrees
» It is perfect for tight spaces, they enable conventional forward & backward
movement as well as side to side even rotation
» High load capacity
» Simple to control
» Less speed and pushing force when moving diagonally
ADVANTAGES 23

24. » It cannot be applied in automobiles because it can reduce mileage of the
vehicles.
» Complex wheel design
» Quick wear and tear
» Installation cost is high

27. Conclusion
» The main advantage of this type of wheel is
represented by the omnidirectional property that it
provides, allowing extreme maneuverability and
mobility in congested environments.
» Reducing workplace injuries is a major factor in
reducing the overall cost of running a company.
