The automaker Nissan has developed a robot golf ball that always finds the hole.
Using a system that involves overhead cameras, the ball tracks to the hole on the green.
If the putt is off-target, the ball straightens its path. And even if the putt isn’t hit hard enough, an electrical motor in the ball provides enough force to move the ball on its own, which means you could avoid the embarrassment of coming up short on those birdie putts. Forever. (Golf)
