We are all makers
Sebastian Neitsch, Jan Bernstein, and Woeishi Lean teamed up to make this Kunstrasen robot, which uses a miniature flame thrower to draw graphics on your (or someone else’s) lawn.
This has to be the most awesome implementation of a turtle bot, ever. I’m not really sure how it works (it’s tough to get a robot to move to exact positions like that), but I definitely want one! [via Dude Craft]
