Abstract

This project presents a simplified version of lower limb exoskeleton design. The proposed powered exoskeleton concentrates at the lower limb of the human body. The simplified design is made using aluminum. The whole system is built with the cost in mind to make it more affordable as the current exoskeleton projects required heavy funding. Inertial Measurement Units is used as sensors and the data from the sensors is collected to actuate the motors. The control is done using the Arduino microcontrollers. The right leg is assumed to be the sound limb while the left limb is considered the unsound limb. A walking algorithm has been proposed and the result has been encouraging as it can perform the walking movement. The left unsound limb managed to mimic the movement of the right sound limb. The data is also captured and transmitted wirelessly using Bluetooth technology.
