- 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.
- Armor was lightweight and reliable (for at least 30 seconds of uptime). Easy to replace.
- Skids need to glide on potentially rough surfaces.
- Invertibility - taller wheels, shorter chassis, skids on top.
- Front plastic should only be used as armor.
Doori 1.1 - 20th Competition Version
- Bearing was added to one side of the Hub to better support the weapon assembly
- Weapon Mounts were updated to include skids in the actual structure
- An old ramp was attached upside down on the top to help prevent a total flipping
- Sandpaper was glued to the outside of the wheels to promote better traction (Thanks Thomas)
- Ramps were kept but were shortened to prevent contact with the floor
- After fixes to the drive system, it was made evident that the weight distribution of Doori made it very difficult to maneuver the bot
- The new design for the skids caused a rocking motion when the robot was suddenly stopped
- The addition of sandpaper to the wheels improved the maneuverability of Doori (Thanks Thomas)
- The addition of the upside down ramp on top appeared to help prevent flips. However, Doori did not suffer any massive hits during its second competition, so it is difficult to say if the upside down ramp totally prevented flips.
- After shortening the ramps, the ramps no longer got caught in the field
Future Plans for Team Doori
- Because Doori's core design was so poor, there are currently no plans for a second version (Doorii)

Recommendations for Future Members
- The design behind Doori is inherently flawed and can't be improved upon without major changes to the design of the Robot.
- Team 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.
- Team 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 concentrate towards the center which, like Doori's case, could make steering very difficult.
- The addition of sandpaper to the wheels helped bring Doori's steering under control (Thanks Thomas). Team Doori recommends other teams try this if their weight distribution makes steering difficult
- 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. (Pls no Lawsuit)
