Overview

• Build an autonomous robot mouse that can find the
  center of a 16 x 16 maze and then calculate the
  shortest path to the center.

Our Design So Far

• Top Down sensors for path/wall detection
• 4 sensors at each corner
• 3 for error correction
• 1 for wall detection
• 2 sensors in the middle for error correction
  during turns
• Two wheels and a ball bearing for mobility
• Stepper motors
