Results - Bracket Style:

  • Emmii vs Thunder Child (Video Link)
    • Emmii's drum did not reach low enough to do much damage against Thunder Child's wedge.
    • Loss was due to the judge decision that Thunder Child dominated for more of the match.
    • Showed that Emmii's drum teeth had too much ground clearance and that its drive train was made useless by picking up the back end of the robot.
  • Emmii vs Revenge of Dr. Super Brain (Video Link)
    • Emmii made some good hits, but after being flipped over too many times, one of its drive motors came detached from its gearbox, rendering it immobile.
    • Problem can be fixed by applying lock-tite to the screws that attach the motors to their gearboxes.
    • RoDS won by judge decision.

Problems:

  • Wires came out of Scorpion mini speed controller every so often. Make sure the screws are tight before matches.
  • Pololu motor detached from gearbox. Use lock-tite to make sure they're secure.
  • Weapon teeth did not go close enough to the ground.
  • Weapon drum likely too small to deal a lot of damage, though weight was taken out of the drum to allow the armor to be larger.
  • Large nature of armor made it easy for other robots to pick up one of Emmii's edges and stop its wheels from contacting the ground.
  • Weapon ESC did not enable the weapon to spin backwards when upside down.
  • Teeth were slightly loose after some testing, but this was fixed by supergluing the teeth into the drum.
  • Had some issues where there was too much friction between the drum and the frame of the robot, but this was fixed by loosening the bolts holding in the press-fit motor and replacing the bearing.

Good aspects:

  • Armor was essentially unharmed. HDPE can be an effective robot exterior.
  • Plenty of space for wires
  • Wall between electronics and weapon to protect electronics
  • Velcro strap to hold battery to electronics wall was a good idea.
  • Weapon spun up quickly, had no major design issues other than the tooth length and the weapon mass.

  • Make sure bolts are lock-tited in.
  • Perhaps use a faster motor.
