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 or Bar-Bus-i, the spiritual successor to Barbi, when competing at Robot Battles due to the lack of a Bus and the inclusion of former Barbi members.

Design Summary

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


  • 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


Maybe like use functional parts
