Problems

  • screws did not have enough contact, too shallow threads
  • tolerances between shaft and ball bearings resulted in shaking that caused screws to come out
  • large regions of useless aluminum on side plates
  • back plastic armor affected wheel contact
  • screws on hub (4-40) too thin to handle impacts
  • open access to electronics by spinning weapon
  • small bearings
  • NEVER TRUST THE DRIVE MOTORS

Good aspects

  • side plastic armor for wheels prevented total destruction of wheel, lasted several hits from a kit beater bar
  • rear plastic armor allowed robot to not become trapped on a flat surface without wheel coverage.
  • heavy weapon and good weapon motor
  • drive while inverted
  • Sturdy axle
  • compact, easy access to electronics
  • low friction between axle and hub
  • powerful motor (FWOOOOOSH)

Changes/Improvements

  • increase depth of screws
  • increase width of axle
  • increase size of bearings
  • increase weapon attachment screw diameter
  • locktight screws
  • install screws into top plate to hold armor down
