team xbot presents X7, our 2007 robot. It's nearly complete in this photo, missing just a few details.
Its features include:
-- 4 CIM, 6WD geared at 17.5:1 for increased torque over typical FIRST drivetrains
-- Capability to quickly switch one pair of omniwheels for a second pair of kitbot wheels for increased resistance to rotation
-- Twin 38" x 44" (~11.5 sq. ft.) corrugated polycarbonate platforms sitting atop gas spring-actuated four-bar linkage lifting platforms.
-- 14" final lift height
-- 2 second lift time
-- 190 lbs. lift capacity

We're 5' tall and weighed ~115 lbs. last night. We haven't done anything at all to lighten most of the robot to date, so losing the little bit of weight we must to pass inspection will be no trouble at all. Already, by lightening some tubing on a plasma cutter and swapping bolts for rivets, we've saved several pounds. The mechanism that allows the platforms to fall has been changed to a design that requires only one motor, saving another several pounds. We have also placed an order for thinner Polygal sheeting that will save nearly 5 lbs. all by itself. We're in good shape.
We've built a simple arm, but there's no weight available for its use, unfortunately. We expected this early in the season, so it's no loss or detriment to our strategy. We've always sought to be one of the best lifting robots in the competition and as such, we focused our effort on making the lifts as easy to use and reliable as possible.

I believe we are ordering through TAP plastics, or Laird

who are polygal distributors.
