Problems

• The three screws holding the bot and the skids in place were difficult to remove because of the threaded standoff in the middle
• Exposed space above and below the weapon ring can be exploited/allows small enemies to evade the weapon
• The motor controller had loose connections
• Weapon ring prone to slipping off the burnt down rubber bearing ring, due to the softness and malleability of the rubber.
• Wheels were prone to becoming loose and slipping off the drive motor shaft

Good aspects

• Can attack from all sides
• Has no exposed, non-attacking sides
• Can drive right side up and up-side-down
• Most Parts are easy to remove/repair/replace
• Relatively difficult to damage severely

Changes/Improvements

• Change the rubber rings to plastic or Teflon (fixes issue of ring falling off)
• Find a better way to secure the wheels to the motors
• Make the robot thinner
• Make the weapon closer to the ground, and cover more of the robot
• Find a better way to hold the robot together
