Mechanical System

Puck Hopper

  • The loading mechanism used a predetermined number of steps to go back and forth. A limit switch was used during testing, but then taken out because an unknown error was causing difficulties.

Firing Mechanism

  • A rubber belt was found and used as the interface between the puck and firing wheel. The original foam material would deteriorate, causing small pieces of foam to enter the gameboard, increasing friction dramatically. The new rubber does not deteriorate and grips the puck much better.
  • Guide rails were implemented for more precise puck positioning.

Gantry System

  • A brushless DC motor driver was donated by Advanced Motion Control (provide link??)
  • The driver allowed for very precise motion control given a voltage applied for a given amount of time. For our purposes this control was precise enough to eliminate the need for any kind of encoding on the gantry.
