Project Description

• Robo-Football Demonstration and Competition
  Development
• Intercollegiate robotic football competition
  with elements similar to American Football
• Will develop rules and quarterback prototype to
  demonstrate some key features of the game

Previous Weeks Action Items

• Item 1 Finish CADing Prototype
• Air cannon, base, drive wheels, and the caster
  wheels are complete and assembled.
• The drive motors, and the cam are also complete
  but not in the assembly yet.
• We still need to CAD the stepper motor, the
  batteries, and the assembly that supports the
  stepper motor.
• Item 2 Build air cannon
• Have not received sprinkler valve so the air
  cannon assembly is only partially completed.

Next Weeks Action Items

• Item 1 Select stepper motor and batteries
• Determine what amount of torque that the stepper
  motor will see and then order it.
• Determine the size that our two 12-volt batteries
  need to be and then order them.
• Item 2 Develop an electrical diagram
• Analyze how the batteries, the motors, and the
  controller need to be connected so that they work
  properly
• Draw a preliminary diagram that shows these
  connections so that we can start planning how we
  are going to wire the robot.
