Don't have anyone to play catch with? Well, the Rollin' Justin robot is capable of catching not just one but two balls at once, once in each hand, which is more than I can say about most people.
By using onboard cameras and processing, this bot is able to track two balls coming at it and adjust itself into position within two centimeters of where it needs to be in a mere five milliseconds. What results is a catch rate of better than 80%. No, it's not gonna get brought in by the Yankees anytime soon, but it sure beats bouncing a ball off the side of the garage.
Oh, hey, apparently it can brew a cup of coffee, too. Check it out in the video below.
