A joke robot made by a few of the 2022-2023 3lb mentors. There hadn't been a drum spinner in the 3lb program for the past 2 years and we thought it would be really funny to have a literal bus as a weapon so here we are. Not counting the CNC work for the bus the rest of the robot was completed within 3-4 days (albeit spread out across several months).

Bus-i.5 also went by Barbii, the spiritual successor to Barbi, when competing at Robot Battles due to the lack of a Bus.

Competitions

State of Franklin Robot Rumble 2023

• Results: 1 - 1
  • Bracket Style: Double Elimination
    • [Forfeit Win vs Iron Clad]
      • We take those
    • [Forfeit Loss vs Feloni]
      • Turns out the robot was never really functional

Robot Battles 71 at Dragon Con

• Results: 1 - 2
  • Bracket Style: Single Elimincation
    • [Forfeit Win]
      • Officially 2 - 2 without ever setting foot in an arena
    • KO Loss vs Sharpie
      • First ever fight was a loss to an actual FTBB kit
      • Randomly turned off after a few hits but still perfectly functional after a power cycle. Best guess is something happened with the switch or a voltage spike occurred due to the lack of capacitors on the weapon esc

Other Fights

• Results: 0 - 1
  • Bracket Style: Individual Fights
    • [KO Loss vs Anomali]
      • Honestly worked surprisingly well
      • Eventually all motors got mechanically disconnected, drive motor pinions came loose, weapon motor belt fell off

Design Summary

Busi is a box shaped drum spinner where the chassis is made of strips of HDPE fastened together using interior nut strips.

Problems

• Weapon
  • It didn't work because of a single broken motor phase so we didn't know the motor was broken until we actually tested it under load
• Chassis
  • Don't tap HDPE, who knew?
• Drive
  • Pinions fell off because they weren't soldered very well

Good aspects

• Weapon
  • Bus
• Chassis
  • It was pretty durable tho

Changes/Improvements

Maybe like use functional parts

Bus-i.5

Drive Motors	1806 brushless motors mounted to the worst spur gearboxes you've ever seen
Drive Motor Controllers	20a Opto Brushless ESC
Weapon Motor	Flash Hobby d2826 1400kv

Design Summary

After donating the only functional bus to Todd as a treat, the weapon was replaced with a bootleg Fingertech beater bar milled out in like a hour and a half and a timing pulley was added to replace the PLA round belt pulley we never actually got to try. That's pretty much it but not having the bus is a drastic enough change that I felt like it warranted a different version name.

Problems

• Weapon
  • Belt still a little loose, honestly don't know why it was so wrong from the belt calculators something must have been cut out very poorly
• Drive
  • Very laggy for some reason, could be ESCs or the garbage gearboxes

Good aspects

It work
