Improve your game with the Tennibot Robotic Tennis Ball Collector. This smart tennis accessory allows you to focus on your skills while eliminating the tedious task of picking up tennis balls. Tennibot uses object detection and computer vision to detect balls on the court and pick them up for you. In fact, it can even navigate on the court autonomously. You can also use the app to customize where you want Tennibot to clear during a session. Moreover, it collects up to 80 balls and works on both clay and hard surfaces. It runs for four to five hours on a single charge and takes 90 minutes to charge completely. After your time on the court, simply roll the device back to your car.
