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 Week’s 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.

CADed Parts

8” Diameter Wheel forDifferential Steering

1.5” Diameter Casterfor Stability

Current Status

Current Graphic– Completed CAD drawings and assemblies of prototype

parts

Design Status– Finalized prototype dimensions– Drive motors and wheels have arrived.

Schedule– Show Stopper: Have not received the sprinkler valve.

Next Week’s 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.
