We're a bit more than 28 lbs., actually. Each module is 5.75 lbs. with wheels, gears, motors, etc. and the frame is 7 lbs. It's close, but a bit heavier nonetheless. There's a fair bit of bulk in the frame where the two halves join together to add rigidity and strength.
Our first foray into the octocanum drive in 2011 -- and one of the first octocanum drives -- was nearer to 60 lbs., so this is a marked improvement.
