Tennis ball machines just got a massive tech upgrade. 🦾🎾 The ACEMATE tennis robot S10 uses 4K binocular vision and Mecanum wheels to actively scurry across the court and rally with you in real-time. We’re talking 360-degree movement, response times around 0.15 seconds, and return speeds up to 60 mph with heavy spin.  It’s essentially a robotic hitting partner that also tracks your performance stats via an app. It retails for $2,499 and is available now. 🎾 #acemates10 #tennisrobot #tennis #sportstech #cooltech
