Outline• Project overview • Block diagram• Design challenges• Individual contributions• Project demonstration• Questions / discussion

Project Overview• Design and build a compact robot to traverse a maze• Use the robot to generate an ASCII representation of the

entire maze• Convert ASCII representation to a graphical image, using

C# host software• Mark light locations on map as they are discovered• Revisit lights intelligently

throughout the maze in a pre-determined,user-defined order

Design Challenges• Small packaging• PCB design• Long-range IR sensor

accuracy• Motor-control for precise

navigation• Effect of battery charge on

motor behavior

Project Demonstration1. An ability to detect proximity to maze walls and prevent wall

collisions. 2. An ability to find specific locations in the maze based on the

placement of colored lights. 3. An ability to turn and change direction of movement. 4. An ability to generate an ASCII representation of the explored

maze. 5. An ability to transfer stored ASCII map to a GUI program on a

desktop computer via USB.
