You know how greyhounds at the dog track run faster because they chase a fake moving rabbit?  That might actually work for you too.

Scientists at the Royal Melbourne Institute of Technology in Melbourne, Australia developed something called the Joggobot, which has basically the same effect as that moving rabbit...for humans.

The Joggobot is a specially-tweaked remote-controlled hovercraft that flies along with you as you run.  You have to wear a T-shirt with a special pattern on it so its sensors can track you.

You can either use the Joggobot as a companion, to run alongside you...or as a coach, who flies ahead of you, challenging you to keep up.

For now, the team has only made an experimental version, and there's no word if or when this might be available in stores.
