Introduction:
Hello there! We are FIRST Tech Challenge Team 6547--the Cobalt Colts--from Overland
Park, Kansas. Last season (2019-2020 FTC Skystone), our team noticed that FIRST has made
publicly available instruction manuals like this one that instruct new FTC teams how to build a
basic drivetrain from either REV Robotics or TETRIX building system components. Our team
is taking steps to mentor and support new STEM, FIRST, and FTC programs within the state
of Kansas and abroad. We know that many new teams may not know how to get started with
robotic construction, so we wanted to provide an extra resource for the teams we are mentoring
directly, along with many more teams who may nd this build guide useful. Our sponsor,
goBilda, agreed to send us a goBilda Master Kit in exchange for our team submitting this build
guide for goBilda to publish. Since we are familiar with goBilda parts, and plan to teach new
teams how to use goBilda’s building system, this was a perfect opportunity for us. As a team,
we have collectively put in hours of building, computer designing, programming, drive-testing,
documentation, and organization to produce this build guide, and we hope that you enjoy
learning how to build a ring grabber for ULTIMATE GOAL using parts from the goBilda Master
Kit. With that said, Happy Building!
