While most tennis ball machines feed from a fixed position, the AceiiLab A1 combines vision tracking with a moving feed point. Changing where the next ball comes from adds different angles, timing and footwork demands to solo practice.
The A1 is designed to make solo practice feel closer to hitting with another player. The machine uses a dual-lens vision system to track the ball and player, then adjusts its position and feeds the next ball.
Originally launched on Kickstarter as Aceii One, the robot has been renamed AceiiLab A1 as part of a brand refresh.
We haven’t tested the A1 yet, so this article is a preview based on manufacturer information rather than a hands-on review. The A1 is currently part of AceiiLab’s Black Friday campaign – check it out here. Via this link, or by using the code TND50, you will get a total of $650 in savings on the AceiiLab A1 right now.
How does the AceiiLab A1 work?
The A1 combines camera-based tracking with a mobile chassis. Rather than simply firing balls from one spot, it can move along the baseline, the sidelines and the service line.
AceiiLab describes the experience as a human-like rally. The robot uses vision tracking to follow the session and repositions for the next feed, launching a fresh ball from its bag rather than catching and returning the original ball.
The AI Vision system recognises the court, player, racquet, landing zones and ball path in order to position the next feed.
The system is designed to work without wearable sensors, using its camera system to follow the player and the ball.

Training modes and app
The A1 offers several training modes, including fixed-position, cruising, central-return, random-ball, sideline-moving and service-line-moving modes.
Users can also create custom drills, adjusting settings such as ball placement, speed, spin, trajectory, interval and number of balls. The accompanying app includes training data and AI coaching features intended to help players review their sessions and identify areas to work on.
The difference is not only where a ball lands, but where the next feed starts. By combining feed positions, target landing zones, timing and shot sequences, players can build tactical drills around the patterns they want to practise. That brings movement, recovery and decision-making into a session, rather than focusing only on repeated swings.
The machine is designed to be portable, with foldable supports, wheels, a removable battery and a detachable ball bag. AceiiLab lists a capacity of up to 120 balls, so players can spend more time hitting before needing to reload. Ball collection is a separate task, although the company offers a smart ball picker in certain packages.

Who is it for?
The AceiiLab A1 is aimed at players who want to practise independently but find other ball machines too repetitive. Its ability to move and vary the next feed could make sessions more engaging, particularly for players working on consistency, movement and recovery.
It may also appeal to coaches looking for another way to structure individual drills. However, the value of its tracking and AI coaching features will ultimately depend on how accurately they perform in real-world use.
Things to consider
The A1 is a relatively complex piece of equipment, with cameras, movement systems, software etc. That makes reliability, setup and ongoing software support important considerations.
Its weight is also worth keeping in mind if you regularly transport equipment to and from the court. And while the company describes the experience as a realistic rally, it is still a machine feeding balls according to its programming, and a ball machine is never a substitute for the adjustments and unpredictability of playing with another person.
The AceiiLab A1 is an interesting development in the ball machine category: a feed point that repositions between shots. Its combination of ball tracking, movement and customisable drills is designed to deliver a more varied solo practice experience.
Three takeaways
- A moving feed point changes the angles, timing and footwork of solo practice.
- Because the machine repositions between shots, you can train real point patterns – recover, and take the next ball from a new position, not a repeating swing.
- It responds to each shot, so the rally stays alive – the session adapts to you the way a real partner does.
