Design and development of an exoskeleton

Control software for an upper-limb assistive exoskeleton, tested in MATLAB simulation before hardware and sensor-based control are added.

The requirement

The problem this answered.

An assistive exoskeleton's control logic has to be right before any hardware moves against a person's arm, so we checked the kinematics in simulation first.

Constraints and operating environment: Upper-limb assistive use; development ongoing.

Vebix scope

What we did.

This is an ongoing project to develop the control system for an upper-limb assistive exoskeleton. We use MATLAB to generate joint movement commands, test the control logic and check the kinematics before any hardware is fitted.

Live visualisation shows how the joints respond and how accurate the control is. The next stages are fitting the hardware and adding sensor-based control, possibly using EMG signals to read what the wearer intends and adapt to it.
