We're getting close to the end of Rio 2016 now, so it's time to celebrate the little guys. The unsung heroes who just get on with their job and let the athletes do their incredible thing.
Case in point, the remote control car that brings the javelins back to the competitors after their throws. BRILLIANT.

The car scoots back to the throwing point, saving everyone lots of time and energy. They also do this for the discus. They're basically the ball boys of the Olympics, and their noble contribution to the Olympic movement hasn't gone unnoticed online.
