According to the Grizzly's specs, it can carry a load of up to 600 kg (1322 pounds) and can travel as fast as 19 km/h (11.8 mph). In the video below it also demonstrates its ability to go all kinds of challenging terrain. It is also packed with a host of sensors that help find its way and it's brains are powered by an open-source Robot Operating System.
Lest anyone think this new robot is going to make life easier on our favorite adventurers anytime real soon, I should point out that it's batteries are only good for about 12-hours max (much less with a heavy load). It then requires a 12-hour recharge time before use again. Something that wouldn't be very easy to do at the South Pole. Still, it is an interesting looking concept. No word yet on price.
