01/29/2007: Drawing off the example robot design in the LEGO Mindstorms NXT kit, I decided to do a little ad hoc work of my own.
In this example, I used two servomotors instead of three, and–in the rear–decided to let it slide instead of use the small wheels that were part of the LEGO example. This is because, using the rear wheels caused the bot to tilt forward. I didn’t like that at all.
For the sensors, I added the contact sensor, the ultrasonic sensor, and the sound sensor.
For operational programming, I used three different loops to test the sensors. Here are the pics of the robot and the program:
