3/13/2022 Racquet Ball Launcher Progress

For "2.5.7 Task 7 - Find and Fling" teams are tasked with launching a racquet ball about 2 inches in diameter into a goal floating in front of the WAM-V vehicle.

Current Configuration

  • Supports only one wheel for launching the racquet balls

  • Does not have a very aggressive tilting option (Note: the target will be below the platform of the WAM-V)

extended backing plate

Future Configurations

  • Use 2 counter rotating wheels to reduce spin & to ensure that the ball floats into the goal and has no chance of bouncing out

  • Very aggressive tilting options may not be needed as the target will be below the platform of the WAM-V

We got inspiration for hood design from the robot FRC team 1678 Citrius Circuits made in 2021. Below are screenshots of their shooter CAD side, front, top, and isometric views.

Using Onshape for their gear feature script is much more forgiving than the Fusion 360 gear script which has no option to revert and edit existing gears.
