Popular Science Bracket: Land Robots Vs. Flying Drones, Round 2

Round 2 polls close Monday, March 25, at 9 a.m. Happy March Madness!

Welcome to round two 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.

After a lively first round, in which you threw your voting power behind the likes of BigDog and the X-47B, (but shockingly managed to eliminate a taxidermied cat-turned-quadcopter and CanBot, a robot that masquerades as a tall boy), we’ve got 16 contenders left. If you need a quick guide to what’s what, go here.

Polls close Monday, March 25, at 9 a.m. Check back later that day for the winners and the next round’s matchups. We’ll keep doing this until we’ve determined the greatest land robot/flying drone in all the internet. Only vote once per poll in each matchup, please. And play nice in the comments. Or don’t.
