Competitions

• Motorama 2015

  • Results:
    • Bracket Style:
      • Victory vs Big Data
        • Big Data's beater was not functional, so it only raced around Emmi trying to get hits.
        • Emmi's drum, after hitting Big Data several times, damaged its own motor controller, disabling the weapon.
        • Emmi won by KO after Big Data lost mobility in its wheels, although Emmi was only mobile in one wheel.
      • Loss vs Devastating Moment
        • Emmi's drum, due to a missing tooth, greatly affected the balance of the driving, causing Emmi's front to bounce up and down.
        • Devastating Moment, a Kit Bot, hit Emmi several times, removing Emmi's top plate and exposing the battery.
        • DM won by KO after Emmi's battery disconnected from its terminals.
      • Loss vs Weta
        • Emmi's movement was spastic yet again and was flipped by Weta, a Kit Bot, several times.
        • Emmi sustained much damage to its plates and had its rear "anti-flipping" bolt driven into the LiPo battery, resulting in a loss and a trip to the trashcan.

  Problems:

  • Rear bolt intended for stopping unlucky flips on Emmi's backside basically exposed the LiPo battery to harm
  • Steel teeth on the drum were not fastened sufficiently for them to stay on, producing balance problems caused by the torque of the drum.
  • The lack of a barrier between the drum and internals led to many replacements of the internals.

  Good aspects:

  • Thick plating prevented any direct damage to internals
  • Can operate when flipped

   Changes/Improvements:

  • Curved Plastic Sides
  • Plastic
  • Better Connected Teeth (to ensure a balanced drum)
  • More Room/Better Spacing for Internals
  • Plate between drum and internals
  • Better Skids
  • Remove Rear Bolt (Designed to prevent being trapped on back, but entered LiPo battery during final fight)

  Notes:

  Emmi used self destruct- it was super effective!
