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!

Prototype Brainstorming

FIRST things first. (ba-dum-tish!) The FRC game this year, Ultimate Ascent, is similar in several ways to last year's Rebound Rumble, but trickily different in others. As in Rebound Rumble, a 15-second autonomous period, in which robots act purely on their programming and not at the direction of human drivers, starts the match. Robots score points by propelling frisbees (not basketballs) into 1-point, 2-point, or 3-point slots, each of which are respectively higher and harder to reach. Ultimate Ascent's title comes into play in the endgame, wherein robots are challenged to climb a tower with three rungs and remain hanging there long enough to score points.

On Kickoff Day, also known as "FIRSTmas" by Walter, the team elected to try a different strategy than we normally do. Instead of trying to build a jack-of-all-trades robot, we decided to specialize on the endgame and design and build a climbing robot.

Today, Walter and Mike brought four prototype concepts before the team to vote on. The choices included: a "side hook" plan, in which the robot grasps the rung of the tower and hoists itself up; a "corner hook" plan, in which the robot would grab onto the corner of the tower and climb up diagonally; a "tow truck" plan, in which the robot would pull itself up with a winch; and an "inchworm" plan, in which an extremely complex robot would yank itself up the tower, flipping over repeatedly in an inchworm-like movement.

With each team member voting for a plan A and B, we ultimately elected to build prototypes for both the "side hook" and "corner hook" plans, and to decide from there which to utilize in our final robot.
