Robot Design Concept
Robot Design Concept
RI3Ds are fully functional robot designs created in the first few days after an FRC game release. They are often made by either FRC alumni, coaches, or university organizations. Their purpose is to showcase an example robot that can be a proof of concept. Given the extremely short production timeline, RI3Ds are sometimes not fully featured and may not solve the engineering problems of the game in the "best possible way." However, they are great examples of simple functioning robots and can be used as a source of learning when designing more complex robots.
This RI3D was made by the University of Minnesota for the 2024 FRC Game, Crescendo. This designs features an under bumper intake. By using 2 rollers and some guiding bolts, the notes can be funneled into the robot.

The Notes are then driven by a linear indexer featuring a single belt. From the indexer, the Notes are then brought to a single horizontal flywheel.

To solve the climbing challenge for this game, this robot features a single stage lift, likely drawn by rope, with a claw at the end.
