The AI-powered machine tracks the ball and the player, moves along the baseline and feeds returns up to 80 mph, aiming to make solo practice feel more like a real match.
The traditional ball machine has a problem: it stands still. AceiiLab is betting that solo practice gets far more useful when the machine on the other side of the net moves like an opponent. The sports technology company has introduced the A1 Smart AI Tennis Robot, a mobile hitting partner built to bring real rally movement to players practicing on their own.
Instead of firing balls from a fixed spot, the A1 uses AI vision and autonomous movement to follow the play. A 4K dual-lens vision system tracks the ball, the player and the court without any wearable sensors. After each shot, the robot predicts where the ball will land, moves into position and sends back the next ball. A differential-drive system lets it travel along the baseline at up to 4 meters per second, and its dual-stage launcher can fire balls up to 80 mph with intervals as short as half a second. Speed, spin, placement and overall difficulty are all adjustable, and the result, the company says, forces players to move, reach and recover between shots the way they would in a match.
A companion app adds structure with AI training courses, customizable drills, competitive challenges and performance tracking. Modes range from fixed-position feeding and random shots to moving drills along the sidelines or service line, and players can build their own shot sequences for groundstrokes, footwork or match strategy. Challenge matches include scoring and rankings, and coaches and academies can use the system to run drills and give individual feedback.
The design is built to travel, with a suitcase-style frame, foldable legs and a ball bag that holds up to 120 balls, and settings can be changed from the app without walking back to the machine. AceiiLab is pitching it in particular for indoor winter seasons in North America and Europe. “Every rally is a chance to learn, improve, and enjoy the game,” said founder Ricky, describing the goal of making solo practice feel closer to real tennis.
The company’s team brings more than a decade of robotics experience, including engineers who previously worked at industrial robotics firm KUKA. The A1 first launched on Kickstarter as the “Aceii One,” raising HK$6.43 million from 679 backers, 212 of them in the U.S. For Black Friday 2026, AceiiLab is offering savings of up to $1,360 on selected A1 packages.
The launch lands as AI-driven training tools move from novelty to expectation across racquet sports. For clubs and academies juggling limited court time and stretched coaching staffs, a machine that can run realistic drills on its own is less a gadget than a way to keep players hitting when a coach isn’t available.
