This document summarizes a student project to develop a robotic arm exoskeleton. It presents the objectives to reduce human effort in lifting and enable disabled people. The methodology uses a solenoid valve, compressed air reservoir, power supply and cylinder to operate the exoskeleton. Applications include lifting heavy loads for construction, rescue operations, and medical care. The conclusion states that documenting successes and failures can advance exoskeleton technology.

3.  A powered exoskeleton, also known as powered armor, exoframe, or
exosuit, is a mobile machine consisting primarily of an outer
framework (akin to an insect's exoskeleton) worn by a person, and
powered by a system of motors, hydraulics, pneumatics or levers that
delivers at least part of the energy for limb movement.
INTRODUCTION

4. Literature survey
 The first attempt to create a powered exoskeleton came in the
1960’s.
 The aim of this project is to develop the mechanical design and
produce the physical implementation of a robotic arm exoskeleton
that has the capability of assisting of lifting the load.
 outline the project requirements, broken down into kinematics,
torque and force, control, and safety.

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 lifting.
It also gives the wearer superhuman powers. So it can
also be used in military and rescue fields.

7. Objective
The main objective is to reduce human effort while lifting the
weight.
Other than that, this mechanism in a robot, enables disabled people
to select this mechanism.
Also, this mechanism can be used in automobile industries. Where,
movement of large size body, which is manual in our project.

9. METHODOLOGY
Solenoid valve

10. It is an electromechanically operated valve. The valve is controlled
by an electric current through a solenoid: in the case of a two-port
valve the flow is switched on or off; in the case of a three-port
valve, the outflow is switched between the two outlet ports.
Solenoid valve
 The potential of using Carbon fibre is under research.
 It may be made of any light weight metals like aluminium, nickel,
titanium and hard plastics.

11. Main Parts
Solenoid valve
Compressed air reservoir
Power supply
Wrist band or control pad
Compressor
Cylinder

12.  One of the proposed main uses for an exoskeleton would be
enabling a soldier to carry heavy objects (80–300 kg) while running
or climbing stairs
 Another area of application could be medical care, nursing in
particular.
 wearable robot allows the wearer to lift 10 times as much as they
normally could.
Applications

13. Lifting heavy obstacles, victims and elderly .
Accelerate wearer’s daily activities and improve recovery.
 Support self-physical training.
 Another area of application could be medical care, nursing in
particular.
Advantages

14. RESCUE
 It can be used by firemen to go into risky and hazardous
environments for rescue operations.
 It can be used to rescue people from the remains of destroyed
buildings in an earthquake.

15. ENTERTAINMENT
 These suits can be used to perform superhuman stunts without
risking human lives.
 It can also be used as a preventive measure in extreme sports like
sky diving, Para gliding …

16. CONCLUSION
 To advance exoskeleton technology at the fastest rate possible, it is
critical that scientists and engineers document and share their
successes and failures with the research community.
 University and institute researchers can identify basic principles
governing human movement with robotic technologies (exoskeletons,
prostheses, etc.) with carefully designed experimental studies.
