Who's a good boy at the Olympics? The Field Support Robot is a good boy! The black and white high-tech contraption made its debut earlier this week as one of a handful of robots designed to streamline the Tokyo Olympic Games. And it can be seen again — essentially playing fetch — during the track and field throwing events over the weekend. The International Olympics Committee says the self-driving robot is able to suss out the "optimal path" to follow when it's chasing after hammers, javelins and all manner of objects thrown by athletes. "This will help reduce both the amount of time needed to retrieve items and the amount of human support required at events," the IOC explained.
