// Challenge Solution
  // Create functions for 6 points: the pre-pickup, the pickup, the lift, the move, 
  // the place, and the departure. Set a small delay between each of these points.
  Position_1(); // Pre-pickup position
  delay(1000);  // Short Delay
  Position_2(); // Pickup position
  delay(1000);  // Short Delay
  Position_3(); // Lift Position
  delay(1000);  // Short Delay
  Position_4(); // Move Position
  delay(1000);  // Short Delay
  Position_5(); // Place Position
  delay(1000);  // Short Delay
  Position_6(); // Departure Position
  delay(5000);  // Long Delay before next loop
  // End Challenge Solution
