Apollo, The Littlest LineLeader

This is Apollo, the smallest NXT based line follower I’ve ever made.  It’s loosely based on A-Maze-Ing, which I designed and built quite a while ago.

Apollo is equipped some pretty cool stuff:

• The new Mindsensors Numpad
• A Mindsensors LineLeader sensor
• Two Rotacaster wheels

The program in this robot is based on the same one I wrote for the Mean Lean Line Leading Machine. I made some improvements, of which includes the ability to enter the PID and speed parameters with the numpad, rather than going through them with the NXT’s arrow keys.  You can also navigate the menu using the “2” and “8” keys for up and down and use “#” to make a selection.

I made a video of Apollo to try and show how the menu and Numpad sensor work but it’s a bit hard to really do it properly with Windows Live Movie Maker.  That’s my excuse for the quality of this video and I’m sticking to it!

The source code for this robot will be part of the next release of the ROBOTC Driver Suite.
