Make: Online reader Baz from Dublin, ireland, sent us this rad video of a low-tech robot lawn mower. He writes:
Self-propelled lawn mower guided by wrapping a string around a couple of posts so it mows a spiral of lawn. Quite hacky, but interesting idea!
In the MAKE offices we’ve been trying to guess what happens at the end. So far we’re thinking the mower flips over, or perhaps it rips its tether out of the ground, mowing wildly amok. What do you think happened when the rope ran out?
Of course, this project is an incredibly great contrast to the R/C Lawnbot we have on the cover of MAKE Volume 22 (and show you how to make inside the issue).
