Henry Evans is co-founder of Robots for Humanity and a pioneer in adaptive robotic technology to help him, and other disabled people like him, navigate the world. At age 40, Evans was left mute and quadriplegic after a strokelike attack caused by a hidden birth defect. Years of therapy helped him learn to move his head and use a finger, allowing him to use a head-tracking device to communicate with a computer using experimental interfaces. In 2013, Evans was a featured presenter at a TED event. He frequently collaborates with robotics teams who develop tools for the severely disabled.
