Robotics researchers are developing exoskeletons and prosthetic legs capable of thinking and moving on their own using sophisticated artificial intelligence (AI) technology. The system combines computer vision and deep-learning AI to mimic how able-bodied people walk by seeing their surroundings and adjusting their movements. "We're giving robotic legs vision so they can control themselves," said Brokoslaw Laschowski, a PhD candidate in systems design engineering who leads a University of Waterloo research project called ExoNet. Exoskeletons and prosthetic devices operated by motors already exist, but users must manually control them via smartphone applications. That can be inconvenient and cognitively demanding.
