Problems

• Not invertible. (Could not flip itself over.)
• Skids got caught in the rough ground and the damaged arena floor.
• Ramp extended beyond the range of the weapon and prevented opponents from making contact with the weapon.
• 1/4" HDPE plastic armor did not work as intended. Instead of deflecting hits, chunks were taken out of the armor.
• Wheels and weapon belt were exposed.
• Had trouble with the tension of the weapon belt.
• Hobbyking weapon ESC did not work. Turnigy ESC worked.
• Because all the weight was concentrated in the center, It was very difficult to maneuver.

Good aspects

• Armor was lightweight and reliable (for at least 30 seconds of uptime). Easy to replace.

Changes/Improvements

• Skids need to glide on potentially rough surfaces.
• Invertibility - taller wheels, shorter chassis, skids on top.
• Front plastic should only be used as armor.

20th Competition Updates

• New weapon mounts were designed with a smooth skid incorporated into the shape
• Ramps were kept but did not make contact with the floor
• Sandpaper was attached to the outside of the wheel for extra traction

Recommendations for Future Members

• The design behind Doori is inherently flawed and can't be improved upon without major changes to the Robot.
• The team of Doori does not recommend using Doori as a starting template for a vertical bar spinner. (Please start from scratch).
• One major benefit to Doori was that it proved plastic armor is a viable option for absorbing some hits.
  • The team of Doori advises vertical bar spinners to consider where their weight is concentrated. Because the weight of plastic is so light, teams may be tempted to let the weight go towards the weapon which, like Doori, could make steering very difficult.

Notes

Name origin

• Doori was intended to be a 'door'stop with a weapon
• Door + i = Doori
• Contrary to popular belief, Doori's name did not draw inspiration from an aquatic Disney character.
