  1. The Fighting Mongooses Ted Keppner Jacques Dupuis

  2. Background Information • Farms run into problems of having to pay for workers to clean up cow bed shavings when they could be doing more important things. • Removing these shavings provides a clean and safe environment for the cows and workers.

  3. Problem Statement • To clean up wood shavings in a barn environment with an unknown size and shape. • Avoid common obstacles found in barns such as stall bars, pipes, cows, workers, etc. • Must deliver wood shavings to a predetermined location. • Must require minimal user input.

  4. Solution • To design an autonomous robot with: • Bumper • Ultrasonic Sensors • Rotary Encoder • IR Sensor • Limit Switch • To pick up the debris off the ground using: • Roller Brushes • Flapped Conveyor Belt • Holding Bin
