This document outlines an exoskeleton, which is a wearable device that enhances its user's strength and mobility. It discusses the types of exoskeletons, their main components like a skeleton, microcomputers, power supply and wrist band. It also describes how exoskeletons like the Ekso suit can help paralyzed patients walk again by powering joints and allowing users to stand, walk and climb stairs. While exoskeletons provide benefits, they also face challenges related to power supply, weight and cost.

3. INTRODUCTION

4. SOME EXOSKELETONS

5. WHAT IS 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.
• It also gives the wearer superhuman powers. So it
can also be used in military and rescue fields.

6. Main Parts
• Skeleton
• Micro Computers
• Power supply
• Wrist band

7. SKELETON

8. 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.

9. POWER SUPPLY
• 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.

10. Wrist Band

11. WORKING OF EKSO
•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. WORKING OF EKSO
• 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.
• It weight 23kg & users can walk at a speed of 3.2
km/hr.

13. Working

14. COMPLICATIONS FACED
• Power supply
• Skeleton material
• Joint flexibility
• Speed of response
• User size
• Cost

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 -more than $45,000.
• Specialized parts are required.
