Land robots vs. flying drones, round 4

Welcome to round four of the world’s nerdiest bracket! To recap: we’ve compiled a list of some of the strongest, fastest, and strangest landbots and sky drones around. Your job: vote for your favorites.

We’re down to the penultimate matchup. If you need a quick guide to what’s what, go here.

Polls close Wednesday, March 27, at 9 a.m. Check back later that day for the winners and the final round’s matchup, which will determine the greatest land robot/ flying drone in all the internet. Will it be DARPA’s BigDog? The fearsome X-47B? The clawed “Eagle” drone? Or Petman, the bipedal gym rat? Only vote once per poll in each matchup, please. And play nice in the comments. Or don’t.

Ready? Go!
