Exoskeleton Spine 7/2025 - now
[ Work in progress ]
Concept
The exoskeleton aims to assist users in moving heavy objects, prevent injuries, and augment motion for the elderly and the disabled in daily activities.
The exoskeleton spine is controlled by detecting electromyography signals (EMG) from the user and controlling the tension of the steel cable through servo motors and BLDC motor.
Foam paddings and springs are added to ensure smooth motion and comfort.

Testing Electromyography (EMG) on an upper-limb exoskeleton
Upper limb exoskeleton is an excellent choice for testing the electromyography sensors that will be placed on muscles.
An electromyography (EMG) sensor detects and measures the electrical activity of muscles, which is generated when muscle fibers contract in response to nerve signals. These sensors use electrodes, typically conductive pads on the skin, to capture the signals, which are then amplified and processed to be displayed as waves or digital data for analysis.
