2. OBJECTIVES
 To design and develop a low cost
lower extremity exoskeleton which will
enable people with paraplegia to
walk and lead a normal life.
 To replicate human walking
mechanism using electrically driven
linear actuators.

3. MOTIVATION
 Many people suffer from paraplegia, an impairment in motor or sensory
function of the lower extremities.
 People with disabilities are looked down in the society. The project aims at
developing a product which will help them overcome their disabilities and to
lead a normal life.
 The technologies currently available in the market are out of bounds for the
common man. The aim is to make this product at a cost which is affordable to
all.

4. SCOPE OF THE PROJECT
 People suffering from paraplegia have to depend on others (using
wheelchairs) to commute from place to place.
 Modern advancements in wearable robotics may make those methods
obsolete.
 With the help of actuators , the human walking mechanism can be easily
reproduced. This mechanism coupled with sufficient supporting system can
enable a person with walking disabilities to overcome their impairment.
 The project aims to make this technology available to the people at a cost
which is affordable to all.

5. PLAN
 We plan on using linear electric actuators.
 Proposed material : FRP (Fiber Reinforced
Plastic)
 Power source: 24V battery.
 When the leg touches the ground it can be
sensed using accelerometer, proximity sensor,
or strain gauges.
 Control using microcontroller
