Welcome to the dedicated page unveiling the journey behind Bipolariti, a 3lb battlebot with dual oppositely spinning vertical disks. Designed and machined by Georgia Tech students of the RoboJackets organization, explore our design process, challenges, breakthroughs, and documentation through videos and imagery. From workshop inception to battlefield triumphs, delve into Bipolariti's story, celebrating the creativity and ingenuity behind its creation.

Competitions

UGA Spring Smash 2.0 - 3lb

• Results: Win/Loss: 1/1
  • Bracket Style: Single Elimination
    • Win against Finished Robot (Auburn Robotics Club)
      • Finished robot showcased a horizontal undercutter. Their robot flipped Bipolariti upside down, and entangled its weapon in Bipolariti's "self-righting" hoops. After the unstick, both robots' weapon belts fell off. Bipolariti's driver reamined in better shape than Finished Robot's, leading to a win.
      • Had Finished Robot not gone in for the second hit after they flipped Bipolariti, they never would have entagled themselves and failed their weapon system. Bipolariti won the match by unintentional entanglement.
    • Loss against SnowStorm (TheNoLives)
      • SnowStorm was a Peter Bar Kit bot using a vertical disk spinnter. Their robot quickly flipped Bipolariti twice, immediately ending the match.
      • Bipolariti left the match nearly unscathed. Its lack of invertibility or self-righting ability was absolutely and supremely detrimental. Not only in that fight, but many others.

Problems

• The wide and narrow horizontal wheelbase made steering difficult. Turning was extremely sensitive, and consistently driving straight forward was nearly impossible.
• The lack of invertibility/self-righting mechanisms was a critical failure. Since bots are almost guaranteed to be flipped in any match, Bipolariti risked flipping itself over every time it made contact with its weapon due to using a vertical spinner. Essentially, to avoid being flipped over and losing the match, Bipolariti had to masterfully maneuver to dodge each and every one of its opponent's attacks while also being careful about dealing damage back.
• The small weapon disks provided little bite. With the inclusion of the "self-righting" hoops, the weapon disk clearance decreased even more. Compared to many other competitive 3lb battlebots, Bipolariti's weapon was not intimidating.
• A wide rectangular bottom plate held the entire machine together. After weight saving, the center of the rectangular base was concerningly thin, making it vulnerable to snapping in half.

Good aspects

• Bipolariti's speed rivaled those of top competitive 3lb robots. Although steering was difficult, with enough practice, Bipolariti's driver could out-maneuver many of its opponents.
• Single-toothed 1/2 inch AR-500 weapon disk. Handled many head-on collisions with other vertical and horizontal spinners exceptionally.
• 3D-printed TPU (thermoplastic polyurethane) plastic armor allowed for realtively easy replacement and adjustment.

Changes/Improvements

• Attempted to solve Bipolariti's self-righting issue with strips of LDPE (low density polyethylene) plastic that would roll the bot onto its wheels when Bipolariti eventually flipped. However, even after heat treatment the plastic was too flexible and easily collasped, proving insufficient and inadequate.
• Because one of the weapon motors caught fire on Friday, March 22, we switched from dual, oppositely spinning disks to a combined, single disk on the front end. Screwed both disks together to effectively form a single 1/2 inch AR-500 weapon. Switching out the remaining functional weapon motor with a larger weapon motor for more torque and speed, Bipolariti now had one powerful weapon instead of two mediocre weapons.

Major Events/Pivotal Moments

• Friday, March 22nd: Fire #1
  • One of the BadAss weapon motors caught on fire. Although the exact reason for the fire is unknown, it was likely due to overtesting before the UGA Spring Smash

• Thursday, March 28th: Fire #2
  • Drive ESC caught on fire.
