SimLearn

On this day, I read over the Lego Mindstorm manual.  I learned how to control the sensors of the robot from the NXT brick.  After experimenting with the different sensors, I created two different cars.  The first one I designed had a touch sensor in the back, an ultrasonic sensor in the front, and two servo motors attached to the body for steering the car.  I was quite surprised at how well the ultrasonic sensor worked.  Although my car was unique and budding with potential, I realized it did not seem practical for the task at hand.  It seemed the car that I had just created would be better served to autonomously travel around a room, avoiding obstacles obstructing its path.  Next, I created a second car using the directions provided in the book.  Essentially, I created a ball retrieval device.  This project was quite interesting as no directions were given to build the base of the car.  After much perseverance and looking at many different pictures of the car from a variety of angles, I was able to recreate the “base car” shown in the book.
