Explanation
• For us to use the car and the NXT brick
with the car, we had to hack into the car.
By this I mean that we had to find input
and output voltages for the car and brick to
get the motor at the right level so that we
wouldn’t fry the motors. These are our
calculations:
Motor                                  Direction              Volts
Drive Motor                            Forward                2.86 Volts
Output power   Volts

Drive Motor                            Reverse                -2.78 Volts                         10           0.71

• This is our robot going forward and
backwards.
• We programmed it not steer but just to
move back and forth.
• The video file name is vid00177
• This is our robot moving left and right and
forward.
• We programmed the car to move forward
and steer.
• The video file name is vid00179a
• This is our robot moving in a figure 8.
• For this we had to program the robot using
multiple blocks telling it to do multiple
things at once…
• The name for this video is Vid00179
She Loves You
• This is our robot doing choreography for
She Loves You by the beatles.

• The video file name is vid00192
