Acemate
AI ChatLast updated:
The Acemate is a specialized tennis training robot designed for real rally play, functioning as an autonomous practice partner on tennis courts. It uses dual 4K binocular cameras and onboard AI to track ball trajectories in 3D with centimeter-level accuracy, predict landing points, and dynamically position itself to catch and return shots. Mounted on four omnidirectional Mecanum wheels, it moves at up to 5 m/s with 0.15-second reaction time for full-court coverage. It launches balls up to 80 mph with spins up to 60 RPS (topspin, backspin, slice, flat, lobs to 8m), holds 130 balls, and offers traditional ball machine modes plus AI coaching via a companion app with drills, shot maps, and performance stats. Ideal for solo players seeking immersive rallies without a human partner, enhancing skills in consistency, accuracy, and endurance on various court surfaces.
