It seems like almost every week, another company is coming out with some type of advancement in robotics. Whether it is Tesla’s bipedal robots that work at their charging station, or a military contractor building new robots for the front line, it is getting pretty impressive what they can do.

In line with these advancements, the Chinese robot manufacturer, Unitree, has recently put out a video of their new quadripedal ‘robot dog.’ This dog isn’t just made to be a friendly pet or an entertaining companion. Instead, it is designed to perform some very impressive tasks in extreme environments.

The robot dog, which is officially called the Unitree A2 Stellar Explorer, is an upgrade to their previous version and is said to be significantly stronger, faster, and lighter than before. It can perform front flips, walk through extreme environments, and much more.

Perhaps most impressive is its strength. In the promotional video seen below, you can see this robot walking and flipping up and down stairs, steep hills, rocky areas, and more. At one point, a 220-pound man even hops up on its back without it struggling at all.

The price for this incredible robot has not been released yet, but some of the other specs have been. It weighs 81 pounds and has a battery life that is expected to last about 3 hours when it is carrying a 50-pound load on its back. During those three hours, it can travel 7.7 miles with the load, or up to 12.4 miles without any weight.

The robot dog can climb up hills with a 45-degree grade, and you can even get an upgrade that will let you replace the traditional ‘feet’ with wheels, so the robot can essentially go rollerblading.

Overall, this robot is very impressive, and it is also one of the first robots that seems to be truly practical. You can strap a backpack or other heavy load onto its back and send it running along. It is easy to imagine how this could be helpful on a battlefield, a construction site, a shipyard, or even a warehouse.

Even when the robot did slip or fall, it was able to recover almost instantly and go back on its way.

To see that this four-legged robot is impressive would certainly be an understatement.
