1 EE396 Project Micromouse Team: Ocha

2 Team Members Kanoa Jou (Programmer) Ryan Sato (Hardware) KiWoon Ahn (Recorder) Alan Do (Programmer)

3 Overview of the Project  To build and design an autonomous robot to find the quickest path to the canter of a maze.

4 Goal  Implementing distance sensors  Implementing stepper motors  LEGO body chassis  Smooth Turns  Find the Center!

5 Block Diagram Side Sensors Batteries Rabbit ADC Motors Maze Solving Algorith m Moving Tracking Code

6 Sensor Module  Side sensors  Sensor layout  Analog to digital converter

7 Sharp GP2D12  Analog IR distance sensor  Range: 10cm – 80cm  High Immunity to ambient light  Self contained sensor

8 Sensor Design Change

9 Inputs from the Sensor  Final Sensor layout

10 A/D Converter  Max154 or MX7828 -8bit ADC with MUX -Conversion time: 2.5μs -Onboard Vref: 2.5v -Supply voltage: +5v -No clock needed -4 inputs -8 outputs

11 Chassis  LEGO

12 Control  Rabbit 2000 Microprocessor

13 Rabbit Ports PortsConnections Port AMotor Circuit Port D – Pin 0Read and Chip Select Pin 1Channel Select Pin 2Channel Select Port EADC Bits

14 Problems Encountered  Hardware  Side sensor minimum range  ADC setup  PCB Circuit design  Use of old hardware  Software  ADC Programming  Maze solving algorithm  Multiple smooth turns

15 Suggestions  Don’t fry the Rabbit  Recheck circuit before soldering  Check circuit before hooking up to power supply  Cover exposed wires  Finish hardware quickly  Time management  Allow enough time for potential problems

16 Future Improvements  Complex algorithm utilizing more sensors  Find center faster  Better choice of the sensors  Easier adjustment of parts  Batteries  More “plug and play” connections  Set earlier finish date

17 Incomplete Tasks  Programming  Maze solving algorithm  Tracking while turning  Multiple smooth turns
