Robotics Monday: Rowing 'Bot

Name of Model: Rowbot
Created by: JP Brown (older site)
Found at:
Last time we featured JP Brown's work, we saw his Rubik's Cube Solver, which was conveniently hosted on his own site. This time though, LEGO® MINDSTORMS NXT-themed blog TheNXTStep brings us his new aquatic robot. This robot has some non-LEGO parts that float (I don't know what they are, exactly, but I am pretty sure it's technically "cheating" some astute commenters filled me in - these are zeppelin parts from the Adventures line (which was out about 8 years ago)), but and the programming and the moving parts are all done with MINDSTORMS parts. You can even see it steer itself with different rowing patterns in the YouTube video:

This is controlled remotely via bluetooth with a .NET program - which means that this isn't completely autonomous, but I suspect that the programming has simplified it to the point where not much is done manually either.

Oh, and DON'T TRY THIS AT HOME KIDS, it's NOT SAFE to risk your NXT by putting it too close to the water. If you are going to try to create something like this yourself, make sure that you can test the non-electronic parts first in a smaller body of water (maybe a full sink or tub) so that you can make sure that the expensive electronic parts will be safe and dry.

The parts that float are from 5956 Expedition Balloon

If by "non-LEGO parts that float" you mean the pontoon-like things it's riding on, those look like the airships from the 1999 Adventurers set 5956 "Air Zeppelin". So yup, they are LEGO :)

See the set in the LUGNET guide
