Arduino Robot Build 0.1

I am a master electrician and an electrical engineering student at the University of Michigan-Dearborn turning my classroom skills into a hobby.  I am working on building a robot platform to experiment with the Arduino Uno  micro-controller.

Purchased parts include: (1) Arduino Uno,(2) Parallax Continuous Rotation Motors.

The body is made from a square piece of Lexan plastic, the motor mounts are cast aluminum angle, the wheels are 1/2" plexiglass, and the third wheel is a chair caster.  There are not any sensors mounted right now.  I programmed the robot using Arduino open source software (See code below). I have it performing forwards and backwards motion, CW and CCW circles, and left and right turns. Each motor is attached to the 5 VDC on the board and their own PWM digital output pin.

#include <Servo.h>

Servo leftMotor1, rightMotor1;

void setup()

{

  leftMotor1.attach(11); //attach motors to proper pins

  rightMotor1.attach(9);  

  delay(1000);

}

void stop()//stop motors between actions

{

  rightMotor1.write(90);

  leftMotor1.write(90);

  delay(1000);

}

void loop()

{

  rightMotor1.write(0);//forward

  leftMotor1.write(101.5);

  delay(5000);

  stop();

  rightMotor1.write(180);//backward

  leftMotor1.write(78.5);

  delay (5000);

  stop();

  rightMotor1.write(0);//turn left

  leftMotor1.write(90);

  delay(3000);

  stop();

  rightMotor1.write(90);//turn right

  leftMotor1.write(180);

  delay(3000);

  stop();

  rightMotor1.write(180);//back right

  leftMotor1.write(90);

  delay(3000);

  stop();

  rightMotor1.write(90);//back left

  leftMotor1.write(0);

  delay(3000);

  stop();

  rightMotor1.write(0);//circle left

  leftMotor1.write(97);

  delay(2000);

  stop();

  rightMotor1.write(85);//circle right

  leftMotor1.write(180);

  delay(2000);

  stop();

}
