Welcome to GROOVI! This is a drum spinner 3lb robot, we finished it at 2am the night before Motorama :)
We manufactured our second edition Groovii over the course of the two weeks around spring break (but hey, at least this time we finished at 11 pm the night before our 2nd competition!)

Problems

Groovi - Motorama Edition
- Nonfunctional drive motor
- Locktight issues/pin in the drive motor was too short
- Was barely enough room for electronics
- Some holes were too small
- Belt was too loose

Groovii - RoboJackets 20th Anniversary Edition
- Belt was too tight, caused too much torque on the weapon motor and prevented its successful spinup
  - Except for that one time in front of the judges after we heat-gunned it
    - And promptly decided not to heat-gun it again before our playoffs match (big mistake)
- Similar locktight issues to Motorama involving the pinion gear inside the drive motors
- Wheel kept falling off because of a warped hub
- Bearings were warped, which made it a lot harder for the drum to turn as smoothly
- Overweight by 0.04 lb
  - Had to drill speed holes and eventually were forced to remove one of the middle steel teeth to avoid disqualification
- Paint job on armor went all over the arena, but at least the top and bottom survived!

Good Aspects

Groovi - Motorama Edition
- Drum was very solid
- Was underweight
- Armor was effective
- Used hella electrical tape to fix switch (was functional at Motorama)

Groovii - RoboJackets 20th Anniversary Edition
- MYSTERY MACHINE MAKEOVER
  - ALL the complements
- Slightly larger chassis meant we had more room for electronics
- Drum still very solid
- Drive train worked well in all of our matches
- Armor did its job
  - RIP Paint Job 2019
- ESCs worked perfectly
