This is How We Volley Part 2: From Paint Sticks to AI


The Journey of the Volley Trainer from Conception to the Court. Part 2: From Paint Sticks to AI

While racquet sports like platform tennis, pickleball, and padel have taken off in popularity, it’s still challenging for players to really focus on their own needs and improve. To that end, replicating shots is not always possible, nor is finding court time, pro time, or time with three other like-minded players. For most people, shots like waterfalls, knicks, and back-side screens, are not easy to cue up during a match, lesson,or even less in a friendly game. 

Considering how far our technology has come in the last 40 years, we quickly realized that vision technology and AI could power a dynamic racquet sports trainer, so Dan and I set out to change the game. 

The Volley Journey 

At the onset of our journey to creating Volley, I used a traditional ball machine propped on paint sticks, making it taller and more mobile to accommodate shots I wanted to practice. To my surprise, other players expressed interest in my setup, even asking if they could buy one!

To create our ultimate trainer, we conducted research, re-modeled existing ball machines, and tried it out with our paddle friends in our hometown of Lancaster, PA. Players were frustrated with the limitations of traditional machines–they couldn't assess a player's position, gauge court dimensions, or replicate shots from tricky angles common in platform tennis. Finally, after three years of development and eight prototypes, we released the Volley Trainer. We offered more than anyone expected –tailored lesson plans, live-play scenarios, video practice footage, and instant feedback. We recognized how this would assist our teaching professionals, allowing for more time next to their players demonstrating technique without having to feed balls.
