Anomali is a horizontal undercutter beetleweight bot. Anomali was designed and built during Fall 2022, and Spring 2023, competing at the State of Franklin Robot Rumble, tying for 5th place.

The main concept of Anomali is a bot that is an undercutter in its intended and flipped positions. Anomali utilizes a bent 1/8 6061 top plate, to angle the weapon close to the ground when flipped upside-down.

The chassis for Anomali is primarily made out of a replaceable TPU shell, with a 6060 1/8 top and 1/4 pocket bottom plate, held together with 6061 hex standoffs.

Competitions

State of Franklin Robot Rumble 2023

• Results: 2-2
  • Bracket Style: Double Elimination
    • Win vs Tailspin
      • Tailspin is another horizontal undercutter. Tailspin placed 1st at State of Franklin Robot Rumble.
      • Anomali won via pit. Weapon system failed to spin up during match. Anomali opted to attempt to win with weapon on weapon collisions, which paid off.
    • Win vs Nasti
      • Nasti is a Robojackets shell spinner. Nasti placed 7th at the State at Franklin Robot Rumble.
      • Anomali won via judges decision. Weapon system was still down, but Nasti took more damage on weapon collisions.
    • Loss vs Performance Anxiety
      • Performance Anxiety is a SSP Kit Bot. Performance Anxiety placed 3rd at the State of Franklin Robot Rumble.
      • Anomali lost via pit. Without a working weapon, Anomali couldn't do much against a wedge bot.
    • [(Video Link) Loss vs Tailspin]
      • Rematch versus Tailspin in the losers bracket.
      • Anomali lost via pit. Anomali was run in its inverted position, hoping that the weapon would work. The weapon still failed to spin up.

Problems

• Our weapon system never worked during a match.
  • Original design left little room between our weapon and motor mounted pulley, causing us to destroy a pulley and motor during testing.
  • Had issues tensioning pulleys, which were exasperated by non-concentric pulleys.
• The inside of the chassis was cramped, and made assembling electronics difficult.
• Could have benefitted from better wheel protection.
• None of our original electronics were in stock, so everything ended up being a substitute.

Good aspects

• The weapon proved very durable on weapon to weapon hits, despite it not working.
• Our chassis held up remarkably well. The TPU protected the electronics and aluminum standoffs remarkably.
  • Because we made several backup TPU chassis and 1/8 aluminum plates, we were able to swap out any part that took damage.
• While the torque motors caused us to be slower, we had much more control over the bot.
• The electronics held up very well. The smaller receiver and weapon esc allowed us to fit everything in the chassis.

Changes/Improvements

• Not entirely sure why our weapon system only worked during testing.
  • Increase the gap between our weapon and pulleys.
  • Use timing belts and 3D printed timing pulleys.
  • Increase diameter of shoulder bolt.
• Chassis design was a bit overkill.
  • Could decrease weight where protection is less needed.
  • Increase space on interior for electronics.
• Wheel Protection
• Use smaller ESCs where possible.
