A better training partner started with one player.

Sportbot began with a tennis player who wanted practice to feel more like a real match.

In 2020, closed tennis courts left Toni Ulčar without his usual training partners. The engineer and tennis player decided to build his own.

His idea was an autonomous moving ball machine that could bring more of a real opponent’s rhythm and unpredictability to tennis and padel practice.

Today, the mission is simple: make advanced training accessible to everyone who loves the game.
