Stay up to date with Rallie's progress, insights, and the future of AI-powered tennis training.
Most tennis ball machines today fall into two categories, but they all miss the mark in a fundamental way.
On one end, there are the affordable, static feeders — machines that shoot balls at regular intervals, often with just topspin and minimal control. On the other end, you'll find more expensive models with oscillation, multiple shot types, and even a handful of programmable drills.
Recently, a new class of machines has started to emerge: ones that claim to rally with you, move around the court, or even collect balls automatically. They look futuristic. But let's be honest — many of these are still in Kickstarter campaigns, and most tennis players haven't actually tried them yet.
We did our first field test and the results exceeded expectations! The system is working perfectly, creating incredibly fast and strong balls with its compact design.
After months of engineering and development, seeing Rallie perform on an actual tennis court was an incredible milestone for our team. The field test validated our core engineering decisions, from the dual motor system to the servo-controlled oscillation mechanism.
We achieved consistent ball speeds ranging from 10-80 MPH with precise spin control, demonstrating both topspin and backspin capabilities that exceeded our initial specifications. Plus, we're revealing our new logo that reflects our commitment to precision and modern design.
