Three-time 2013 Alpine skiing world champ Ted Ligety recently strapped a GoPro camera on his person during a training run down next year’s Olympic giant slalom course in Sochi, Russia, so that fans could see what he sees on his way down the hill. “It will be the longest GS on the World Cup, ranging from a 1 min 30 secs, to 1 min 40 secs,” the giant slalom specialist and gold medal favorite wrote on his website. “My legs were burning midway not to even mention the bottom. Enjoy!”
Puma has introduced the “BeatBot,” a self-driving, line-following robot that runners can program to move at a specific pace around a track.
That means one could race against a robot-version of Usain Bolt‘s 100m world record of 9.58 seconds, with BeatBot’s top speed at just over 27 miles per hour.
The BeatBot can also navigate track curves, as shown in the video above.
Puma plans to roll out BeatBot to various track programs around the world over the year.
