Competitions

State of Franklin Robot Rumble 2023

• Results: 1-2
  • Bracket Style: Double Elimination
    • Win vs. Feloni
      • Feloni is the other RoboJackets 3lb beater bar from this year
      • Our weapon never spun up, as we turned the transmitter on with the stick halfway up
      • Driving was difficult, as it seemed to constantly lag and cut out
      • Feloni landed several big hits, but they ended up knocking themselves out
    • Loss vs. Alpha Raptor II
      • Alpha Raptor II is a lifter, which finished 4th overall
      • Its armor was mostly titanium, so we weren't able to do much damage
      • One side of our drive eventually failed and we were counted out
    • Loss vs. Cherno Alpha
      • Cherno Alpha is a FingerTech beater bar kit bot, which finished 7th overall
      • They box rushed us and took out one of our wheels soon after

Problems

• Weapon
  • The ball bearings used in the weapon exploded from a weapon-on-weapon impact in our first fight
  • The bolts attaching the weapon motor backed out (we should have used Loctite on them)
  • The weapon was a bit weak, as we had to shave a lot of weight from it the night before the competition
• Chassis
  • The chassis design was very heavy, which meant that we didn't have enough weight for wheel guards or other improvements
  • The titanium wedge had too much ground clearance, so we weren't able to get under opponents
  • The bolt on the inner part of the wedge got sheared off during our first match
• Drive
  • Exposed wheels were a liability, as they could be easily attacked by opponents
• Electronics
  • We had issues with the drive cutting out throughout the competition, which was caused by either a faulty drive ESC or the receiver
  • The power switch was hard to access and we ended up stripping the bolt

Good aspects

• Weapon
  • Aside from the first match, the weapon was very robust and didn't stop spinning
  • We replaced the bearings with HDPE spacers mid-competition, which was janky but held up surprisingly well
• Chassis
  • The chassis held up really well, as the only structural damage was the 1/8" aluminum back plate being slightly bent in
  • The wedge did a good job at deflecting hits and didn't take much damage
• Drive
  • We coated the wheels with latex, which gave us pretty good traction
  • We were able to drive well while inverted and flip ourselves back over by running into a wall
• Electronics
  • We left plenty of space for electronics, which made it easy to fit all of them in the robot

Changes/Improvements

• Weapon
  • A lighter weapon motor would be helpful, as we initially planned to use one but weren't able to get it due to supply issues
  • Using 3D printed timing pulleys would also reduce weight
  • With that extra weight, we would probably increase the weight and size of the weapon
• Chassis
  • Make the chassis out of a mix of aluminum and TPU (similar to Anomali), which would significantly reduce weight
  • Add forks to get underneath other bots
• Drive
  • Have the wheels set inside of the chassis, so they would be more protected
