Brain-Machine Interface for Robotic Exoskeleton Control

The system from the registration and processing of electroencephalographic signals (EEG) allows the control of the movement of robotic exoskeletons of the upper or lower limbs.

The brain-machine interface records the person’s EEG signals using surface electrodes and processes these signals to detect brain patterns associated with the person’s upper or lower limb movement imagination or relaxed state. Depending on the brain pattern detected by the brain-machine interface, a command is sent to control the movement of the robotic exoskeleton. Below is an image of a brain-machine interface developed to control the gait of a lower-limb exoskeleton.
