Researchers in the University of Minnesota’s College of Science and Engineering have developed a new noninvasive system that allows people to control a flying robot using a brain-computer interface. The study has the potential to help people who are paralyzed or have neurodegenerative diseases.

 

The open access study was published in IOP Publishing’s Journal of Neural Engineering.

 

Five subjects (three female and two male) who took part in the study were each able to successfully control the four-blade flying robot, also known as a quadcopter, quickly and accurately for a sustained amount of time.

 

“Our study shows that for the first time, humans are able to control the flight of flying robots using just their thoughts sensed from a noninvasive skull cap,” said Bin He, lead author of the study and biomedical engineering professor in the University of Minnesota’s College of Science and Engineering.

 

He said this research is intended to help people who are paralyzed or have neurodegenerative diseases regain mobility and independence by controlling wheelchairs, artificial limbs, or other devices.

 

Mapping signals from the motor cortex. The noninvasive electroencephalography (EEG) technique records electrical activity of the subjects’ brain through a specialized EEG cap fitted with 64 electrodes.

 

The researchers said the brain-computer interface system works based on the geography of the motor cortex — the area of the cerebrum that governs movement. When we move, or think about a movement, neurons in the motor cortex produce tiny electric currents. Thinking about a different movement activates a new assortment of neurons.

 

Sorting out these assortments laid the groundwork for the brain-computer interface used by the University of Minnesota researchers, He said. This new study builds upon previous research at He’s lab where subjects were able to control a virtual helicopter on a computer screen.

 

“We were the first to use both functional MRI and EEG imaging to map where in the brain neurons are activated when you imagine movements,” He said. “So now we know where the signals will come from.”
