5. 1. Powered Exoskeleton – use batteries or electric
cable connections to run sensors and actuators.
2. Passive Exoskeleton – donot have any electrical
power source and can be used for weight re-
distribution and energy capture.
TYPES
6. 3. Pseudo-Passive Exoskeleton – have
batteries, sensors and other electronics, but
they are not used to provide actuation.
4. Hybrid Exoskeleton – are wearables that
have all the controllers and sensors of a
powered exoskeleton but use FES as actuators.
7. 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.
10. 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.
11. 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.
13. 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.
14. 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.
15. COMPLICATIONS FACED
• Power supply
• Skeleton material
• Joint flexibility
• Speed of response
• User size
• Cost
16. Advantages
• Disability no longer remains as a
permanent issue.
• Increased mobility & performance.
• Improves quality of life.
• Expanding markets and newer jobs.
