(...) Those are a good all-LEGO solution... but they tend to splash. A lot. This isn't fatal, but means either "splash shielding" the electronics (which requires more weight), or making the entire robot bigger (so the splashing wheels aren't close (...) (17 years ago, 13-Sep-07, to lugnet.robotics)

It's a little bit risky (usually, when my programming skills fail the robot doesn't end up stranding in the middle of a lake... or worse, on the bottom), but it brings up a whole new range of problems and (...)
