Hydrogen Sports

Hydrogen Sports makes the Proton, a compact smart tennis ball machine designed around portability and software control. At around 17 lb, Proton is much lighter than many traditional machines, while its app lets players aim shots around the court, build custom sequences and control speed, spin and placement from a phone or compatible watch.The Proton is Hydrogen Sports' main tennis product and takes a software-first approach rather than relying on a large control panel or a heavy chassis. Its quick-swap battery, 100-ball hopper and tap-to-aim interface make it particularly suited to players who regularly carry a machine to public courts and want programmable practice without a full-size club machine.
