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.
- Chimney Climber: August 2006 (original design)
- NeXT Chimney Climber: February 2007 (faster)
- Self Stabilizing Chimney Climber: August 2008 (more stable and smarter)
- Compact Chimney Climber: July 2009 (NXT 2.0 Only)
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.
