What if people who are paralyzed could use their brainwaves to get up out of wheelchairs and walk away? That's exactly what researchers from the University of Houston are hoping to accomplish with the latest evolution of robotic exoskeletons. They're turning to mind control to move these high-tech mobility machines to the next level -- and take patients with them.
The idea for for a mind-controlled robotic exoskeleton came to engineering professor Jose Contreras-Vidal, the project's lead, after Duke University's Miguel Nicolelis demonstrated that electrode arrays implanted in monkey brains could pick up on the neuron-firing patterns that occur when the monkey thinks about walking.
"Contreras-Vidal's group found out they could get the same effects using EEG (electroencephalography) to control an exoskeleton. EEG doesn't have the spatial resolution of an implanted electrode array, but it is noninvasive and has the added benefit of being able to measure electrical activity across the entire brain," Popular Mechanics reported. … Read more
