A team of dog-like robots was able to tow a box truck across a parking lot in this bizarre video put out by Boston Dynamics.

In the video, two strange, yellow, four-legged robots march across a paved lot and into view, slowly revealing a team of 10 robots, all working together to pull a box truck attached to two pieces of rope.

Boston Dynamics says that the robots towed the truck on a 1 degree uphill with the truck in neutral. The pooch-like machine, called SpotMini, will be available for commercial sale sometime this year.

If it takes 10 of these machines just to tow a box truck, how many would it take to haul an entire big rig?

Check out the clip of the robots at work, below.
