Just before Thanksgiving, the Internet lit up with the remarkable video of Boston Dynamics' robot Atlas doing a backflip.

It was pretty amazing to see a humanoid-shaped machine doing things that would be hard for most humans. Given all the interest in Atlas, I thought it was a good time to remind everyone about the other non-humanoid robots Boston Dynamics is building. These are the ones that have the "big freaky" factor.

Perhaps it's the strange gait of Spot the robot dog or the headless SpotMini (seen in this video) or the nothing-like-that-exists balance of Handle.

In all cases, they live in their own kind of uncanny valley.

The thing to remember is that something like these machines will likely inhabit the world we're now building. In fact, it may be that a lot of these machines will be inhabiting our spaces. Eventually, I suppose, we will cross the uncanny valley and their weirdness will be just commonplace.

I hope I will be around to see it — I think.
