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 6061 1/8 top and 1/4 pocketed bottom plate, held together with 6061 hex standoffs.

Competitions

State of Franklin Robot Rumble 4/1/2023

• Results: 2-2 - Tied 5th with Feloni
  • 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 ring 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.
    • Loss vs Tailspin
      • Rematch versus Tailspin in the losers bracket.
      • Anomali lost via pit. Anomali was run in its inverted position, as the weapon worked that way. The weapon spun up, but not well, and after a few weapon on weapon collisions, the threads on our shoulder bolt sheared.

RoboJackets Grudge Matches 4/29/2023

• Results: 4-0 - 1st Place
  • Bracket Style: Double Elimination
    • Win vs Scampi
      • Scampi is a RoboJackets vertical spinner. Scampi tied for 5th at Grudge Matches.
      • Anomali won via tapout. Anomali tore off Scampi's weapon mount early into match.
    • Win vs Waluigi
      • Waluigi is a RoboJackets vertical spinner. Waluigi placed 2th at Grudge Matches.
      • Anomali won via double knockout judges decision. Waluigi's drive was mostly dysfunctional, and Anomali bullied them, before getting entangled in the arena's duck tape.
    • Win vs Feloni
      • Feloni is a RoboJackets vertical spinner. Feloni placed 3rd at Grudge Matches.
      • Anomali won via judges decision. Anomali dominated the fight early on, before it's rear pulley gave out.
    • Win vs Nasti
      • Nasti is a Robojackets ring spinner. Nasti placed 4th at Grudge Matches.
      • Anomali won via judges decision. Having run out of Onyx pulleys, Anomali ran with an ABS pulley, which broke on the first hit.

Fall 2023

• Results: 1-0
  • Pick-Up Matches
    • Win vs Bus-i
      • Bus-i a mentor created bot made of scrap material
      • Anomali won via knockout. Anomali disabled Bus-i's weapon and drive. Anomali's weapon lasted most of the match, until the two screws holding it to the top plate vibrated out.

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 ultra 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. Discovered that weapon failures were largely due to a grounded motor coil.
  • 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.

Anomali V1.6

Created by: Ryan De Angioletti, Rafael Sena, Ian Kwuan

Mentor: Jacques Wang

Max Weapon RPM	7560 (theoretical)
Min Spin Up Time	~1 second
Drive Speed	~4ft per second

Problems

• Rear pulley kept on getting worn down and hit by our weapon.
• Timing belts kept on falling off destroyed pulleys, or stretching.
• The inside of the chassis was cramped, and made assembling electronics difficult.
• Despite using torque motors for drive, we lost pushing matches.
• Could not figure out how to get our 4s batteries into the bot, and had to use 3s.

Good aspects

• The weapon finally worked.
• We took no damage the entire day, except on our pulley and weapon.

Changes/Improvements

• Improve reliability and durability of weapon assembly.
  • Increase the gap between our weapon and pulleys.
  • Use timing belts and 3D printed Onyx timing pulleys not ABS.
  • 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.
• Change drive motors.
