Overview of the Project

• Traditional top down style mouse
• Implementing infrared sensors
• Implementing stepper motors
• Begin with an easy design
• Making mice a wall hugger or random turns
• Design more complicated algorithm
• Mouse can find the quickest way to the center

• Inputs from the sensors
• Algorithm
• Code

6
Inputs from the Sensor

• Sensor layout

Algorithm

• Right wall hugger
• Go straight while front sensor is false and right
  sensor is true
• Turn right when right sensor is false
• Turn left when right sensor and front sensor is
  true.

Code

• main()
• While(1)
• / keep straight if there is a wall to the
  right of the mouse /
• while(RSEN1 1 RSEN2 1 RSEN3

• go_straight()
• / turn right if there is an opening on the
  right wall /
• if(RSEN4 0 RSEN5 0 RSEN6 0)
• turn_right()
• / Checking for a wall in front /
• if(FSEN1 1 FSEN2 1 FSEN3 1)
• / turn left if there is a wall on
  the right /
• if(RSEN1 1 RSEN2 1 RSEN3
  1 RSEN4 RSEN5 1 RSEN6 1)
• turn_left()
• / turn right if there is no wall to
  the right /
