              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

Steering Motor                         Left                   2.22 Volts
                                                                                                  30           2.21

• 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
