Georgia Tech researchers have developed the first-ever human scale robot that can return a tennis shot. 🎾 High-res cameras and computer vision algorithms allow the robot, assembled using a specialized tennis wheelchair, to track down the ball and hit it back to a human player. It’s named ESTHER (Experimental Sports Tennis Robot) after the legendary wheelchair tennis athlete Esther Vergeer who was undefeated in singles for ten straight years.
