This past summer (and still) I've been refurbishing the bannister on my house. This is what kept me from building robots.
I would be painting those planks today, but the wheather called for fooling around with my 6WD RC toy. Maybe a 6WD robot some other day.
Yep, that's 20 m plus the stairs.
It looks real nice, I gotta say. Nice complimentary color to the stain you used. The neighbors should cook you a fat dinner for the work at the minimum.
