Outlook

• Attempt to have a bi-directional mouse
• Design an algorithm that would work efficiently
• Attempt to find center and map out maze
  efficiently
• Basically a mouse that would find the center (not
  necessarily win the entire competition)

5
Modules
Chassis

• Build it simple and lightweight
• Aluminum 90-deg. Angle Bars
• Holds motor and batteries and everything else

Drill it

(JUST IN CASE!!!)
9
Modules

• Sensors
• Top-down sensors
• Read and track the top of the walls
• Sensors directly in front and back
• Have sensors in front to detect what lays ahead
• Also have sensors on the side to keep the mouse
  aligned

Sensors
Proposed Sensor Layout
11
Modules

• Rabbit
• Heart of the mouse
• Sends command to motor
• Receives input from the sensors
• Inappropriate use would cause malfunction
• Cost 50 to replace the rabbit

12
Problems

• Getting the motor running
• Some ports dont work
• Wrong ports for output and input
• Sensors not working correctly
• Not enough current going through the motors (LED
  drawing too much current)
• Connecting the computer to the rabbit
• Delivering the wrong amount of voltage to each
  component

13
Problems

• Building the Chassis
• Designing, finding right parts at right prices
• Band-saw broke. Had to cut out chassis by hand
• Mistakes in measuring and building the chassis
• 90 deg Angle Bars not 90 degrees, causing
  difficulty to place motors

14
Potential Problems

• Programming
• Being able to create a working and efficient
  algorithm
• Being able to actually program the mouse
• Finding the right input and output for the rabbit
• Mapping maze
• Keeping track of location of the mouse
• Debugging the code
• Using Dynamic C

15
Potential Problem

• Time
• We might not have enough time to finish the
  project
• Meeting time conflicts among team members

16
Time Line
3/13 Finish Chassis and Design Layout
3/27 Assemble Everything/General outline of code
4/3 Finish Code
4/10 Get the mouse moving
4/10-END Debug
PAU!!!
