New to FIRST?

Hello, Robolions team members, mentors, friends, and community members! Welcome to "The Fourth Law of Robotics," home to University City High School's FIRST (For the Inspiration and Recognition of Science and Technology) Robotics Team. We hope to use this blog to inform you about what we're up to.
We compete in the FRC (First Robotics Competition), an annual competition where we have six weeks to build a robot from scratch. This year's game is Recycle Rush. We'll post updates here to let you all know what we're up to with building (and competing with) our robot!
We also are now competing in FTC (First Tech Challenge), the next level down from FRC. The game was called Ring It Up!

February 12, 2011: Great Progress!

These last two weeks have been very productive - too productive, in fact, to leave time to post. Most of the progress has been on three areas: the robot's line tracking for autonomous mode, the lifting arm for hanging the tubes on the wall, and Little EVA deployment. And boy do we have some progress. Here's a video from Thursday of the robot tracking the forked line that we've set up on some carpet.

This next video, from a few days ago, shows prototyping work on the lifting arm.

But today, the arm was fully mounted, and we got it to hang tubes on a wall equivalent to that on the competition field. Watch the first tube be hung, with Mike driving:

This is the winch that powers the arm. The grey cylinder, a Fisher-Price motor, is controlled by a Victor motor controller between the braces for the gearbox stand.

The current version of the arm is only able to reach the middle level pegs, but ideas have been floated to extend its range, and about Little EVA deployment. Perhaps some of them will come to fruition tomorrow.
