Compact Chimney Climber

Compact Chimney Climber from the Discovery Book

Most NXT contraptions that move with wheels go forwards, backwards, left, or right. This robot can do none of this, but instead it can go up and down. This robot is featured in Chapter 15 of the Discovery Book.

Every time I created a new climber, I tried to tackle a new design challenge, to make the robots faster, stronger, more stable and smarter. Follow the links below, and read the pages in order to learn about my findings in the design process.

I never made a video of this robot, but I found this video on Youtube made by one of the readers. Start at 12 seconds in the video.

Building and Programming this Robot
Instructions for building and programming this robot are included in The LEGO MINDSTORMS NXT 2.0 Discovery Book. It can be built with just the pieces in the NXT 2.0 kit.

    Hey Laurens- after exhausting every page of your “Discovery” book, I just had to get the “Inventor’s Guide” book. I’m working through it now and looking forward to learning from your other projects. The CCC was one of my favorites.

        1. Gil,

          If you built it, you must have the book, which also contains the programming instructions. (?)

          If you use the menu at the top of the page, or if you read two comments down, you’ll find a link to the download page.


    1. Checked means that you should put a check mark in the check box. If you’re having trouble with the program, just download the ready made program from this site. (Books > Discovery Book > Downloads).

    Very cool robot! I’ve built it, but it is just too boring to program it. Do you know where the link is so I can just download the program?
