INTRODUCTION

SOME EXOSKELETONS

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.

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

SKELETON

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.

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.

Wrist Band

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.

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.

Working

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

Advantages• Disability no longer remains as a

permanent issue. • Increased mobility & performance.• Improves quality of life.• Expanding markets and newer jobs.

Disadvantages• Weight

• Expensive -more than $45,000.

• Specialized parts are required.

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