Video: Baseball-playing robot swings, hits and catches with pinpoint accuracy

Researchers at the RAI Institute in Cambridge, Massachusetts, have developed two robots capable of playing baseball with human-like speed and precision. These robots can throw, catch, and hit baseballs, demonstrating advanced reflexes and control. The system uses soft joints and adaptive control to absorb impact forces, allowing smooth and safe interactions with the ball. Sensors track the ball’s trajectory, while prediction algorithms enable the robots to position their gloves accurately and respond almost instantly to throws. The robots can throw at speeds up to 70 mph and catch or hit balls thrown at speeds up to 41 mph and 30 mph respectively, from distances around 7 meters. The robots’ arms are designed with lightweight materials like carbon fiber rods and flexible joints, combined with electric actuators for quick, smooth movements. Their low center of gravity enhances stability during swings and catches. Using ordinary computer hardware, the system integrates live camera feeds with motion models to guide precise movements. The software continuously adjusts for the ball’s unpredictable spins and curves
