    Gamified Competition

    • Random Shot Rally

      Aceii One predicts your shots but also keeps you guessing with unpredictable returns. Irregular ball placement forces you to cover deep zones and sharp angles-simulating a high-intensity match that sharpens reflexes and tactical adaptability.

    • Center Court Rally

      Wherever you hit, Aceii One tracks the landing spot and sends the ball back to the center with consistency. Predictable ball placement makes it ideal for warm-ups and rhythm practice.

    • Moving Line Rally

      Automatically repositioning on the baseline or service line, it reads your shot and returns straight down the line-pushing you to improve footwork and sharpen directional control.

        Tech Behind: Stronger

        • Innovative Dual-Stage Acceleration System

          While typical dual-wheel feeding systems simply push the ball, Aceii One delivers two-stage independent acceleration:

          Stage 1:          Initial speed — reduces feed time by50%
          Stage 2:          Motor-boosted thrust —20%faster speed than standard dual-wheel systems

        • Exclusive Vertical Stereo Vision+

          While others rely on monocular vision, wearables, or limited horizontal binocular systems, Aceii One's exclusive vertical binocular design delivers pure vision tracking up to30 meters—capturing serves up to130 mphin real time, with no sensors required.  —Your court deserves smarter "eyes"

          Creative Drills

          • Drills that Come Alive

            Deep & Short Mode

            Cruising Mode
            Baseline feeds at multiple fixed spots for basic practice—build muscle memory and improve shot consistency.

            Fixed-point Mode
