3. INTRODUCTION
 A powered exoskeleton is a mobile machine that is wearable over all or
part of the human body, providing ergonomic structural support and powered
by a system of electric motors, pneumatics, levers, hydraulics or a
combination of cybernetic technologies, while allowing for
sufficient limb movement with increased strength and endurance.

4. Typesof EXOSKELETONS
KNEE EXOSKELETON
HIP EXOSKELETON
 ANKLE EXOSKELETON
 MULTIPLE JOINTS EXOSKELETON

5. WHATIS THE NEED OF AN
EXOSKELETON?
 It is a suit which assists the wearer by boosting
their strength and endurance. So it is used by
paralyzed patients for walking.

6.  Italso givesthe wearer superhumanpowers. So it
can also be used in military and rescue fields.

7. MainParts
 Skeleton
 Micro Computers
 Power supply

8. SKELETON
Exoskeletons are not only designed for specific body parts; the exoskeletons may
be designed more generally for only one hand, a leg, or even the complete body.
Thus, the separation of the classes demonstrates the most common body parts
exoskeletons can be built for. The full-body class refers to the exoskeletons made
to assist all the limbs, or most of the body.

9. MICROCOMPUTERS
 Microcomputers control the movements
of various motors or hydraulic cylinders
associated with the joints.
 It sends signals to various joints as per
the required mode.

10. POWERSUPPLY
 These can be powered by an internal
combustion engine, batteries or potentially
fuel cells.
 Regenerative methods like using
piezoelectric shoes or power producing
pendulums as in the case of kinetic
watches will increase the power backup.

11. WORKING OFEKSO
 Ekso suit is used by paralyzed patients for
walking.
 Users can stand, walk & even climb stairs.
 It is powered by 4 motors one at
each hip & knee joint that are controlled by
micro computers.

12. WORKINGOFEKSO
 Users can balance using crutches.
 Users select different modes from the wrist
band.
 It also uses motion sensors to study the walking
style of users.
 Itweight 23kg & userscan walk at a speedof
3.2 km/hr.

15. Advantages
 Disability no longer remains as a permanent issue.
 Increased mobility & performance.
 Improves quality of life.
 Expanding markets and newer jobs.

16. Disadvantages
 Weight
 Expensive
 Specialized parts are
required.

18. Conclusion
The conclusion of exoskeleton is to paralysed person can walk again and
make their life easy, and they can live normal life.
