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

3. 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
