“Oh it’s turning. Brake! Alright, we’re scared but we’re good.”
The Tesla Model S had only gone a few feet, rolling mostly straight from one empty spot in the parking garage to another. The driver wasn’t actually behind the wheel, though. He sat in the passenger’s seat, donning an EEG headset that allowed him to control the vehicle with his mind. Meet Teslapathic.
This feat is the brainchild of California-based technologists Casey Spencer, Lorenzo Caoile, Vivek Vinodh and Abenezer Mamo. Their team used Spencer’s 2015 Tesla Model S 85D for the hack, and their project placed third at the Cal Hacks event for university students this month.
The team only had 36 hours to make Teslapathic happen for the hackathon. In their setup, an EEG headset translates the brain activity for “stop” or “go” into analog signals broadcast by an off-the-shelf RC radio and articulated actuators on the pedals and a motor on the steering wheel, according to the team’s description.
A machine learning training program turned the brain activity into specific commands. For “go,” Spencer thought about tapping his right foot, and for “stop,” he thought about clenching his left hand. The analog signal for “go” caused a linear actuator affixed to the brake pedal to recede, and the actuator on the gas pedal to engage. For “stop,” it was the opposite.
