Introduction
The
NXT Rover has been my most successful and sought after project
of all time.
This
jeep is made from pieces only found in the LEGO Mindstorms
NXT set apart from the wheels and
the LEGO Technic Speed Computer which I bought on ebay. This was
the biggest and most challenging project I have made to date and
uses nearly all the pieces in the set. I worked on it non stop for
a total of about 2 days until I got the shape and look that I wanted.
After that it was just touching up, such as adding the 4 Bionicle
pieces above the wheels and the flag above the Speed Computer.

Steering And The Bumper
The
steering uses 2 worm gear screws and one motor. In the programs,
the motor rotates 15 degrees clockwise to turn left, and 15 degrees
anti-clockwise to turn right. I had some difficulties when it came
to giving the wheels enough room to move without hitting the body
of the Rover. I altered the height of the 4 Bionicle pieces and
was able to make some difference, but the car can still only turn
in large circles.
The rear bumper uses the touch sensor to register a bump from behind.
I expanded its range by putting a long beam onto it and the added
the rubber pieces to cushion it a bit. The front bumper is just
there to look good!
