Abstract

Exoskeleton as a wearable robotic machine has a huge potential to be used in medical, industrial, civilian and military field as it can increase the user’s strength and endurance. The scope of this project covers three major engineering fields which are mechanical, electronic and programming engineering. Design of the physical arm exoskeleton structure, actuator controller, and the microcontroller programming are included in this paper. A cost-effective liner actuator which is able to generate large torque is used in the design. For the movement capturing part, two low-cost force sensitive resistors which are able to provide enough accuracy required to detect user motion are used. A linear actuator which can provide sufficient thrust and will not consume any power supply at any stationary position is chosen to drive the exoskeleton and for power saving purpose. The design arm exoskeleton has been tested to be able to lift up 15kg weight and it is able to react according to the user arm movement.
