    you can make it long to dsitribute the weight over a wide area and is low to the ground.

    how would this work on the figure 8 track, Wouldnt it would only follow one half of the track?
  • Joshua Wilkinson
     
    it would work on the other tracks if the robot dosent drive off the line a lot.

  • When line following, the robot will try to align itself centered over the boundary between white and black (not centered over the black line), with black to the robot's left.  Here the brightness seen by the sensor is halfway between the black/min and white/max readings
    • Joshua Wilkinson
       
      This would be useful since we get the value when its over the tape and table, we can also find the value of the sensor when its directly over the tape then the table seperately.
  • When prompted to sample the "Min" or "Black" reading, position the sensor so that the red spot is centered over the line and then press the Enter button on the NXT. When prompted to sample the "Max" or "White" reading, position the sensor so that the red spot is completely over the surface away from the line and press the Enter button on the NXT.

    1.Click the Select a VI icon or text on the Functions palette.

    2.Navigate to the VI that logged the front panel data and place it on the block diagram.

    3.Right-click the VI and select Enable Database Access from the shortcut menu. A yellow box that looks like a file cabinet appears around the VI.

    4.Right-click the record # terminal and select Create»Control from the shortcut menu. LabVIEW adds a numeric control to the front panel you use to enter a record number.

    5.Right-click the invalid record # terminal and select Create»Indicator from the shortcut menu. LabVIEW creates a round LED that indicates whether the record is valid.

    6.Right-click the front panel data terminal and select Create»Indicator from the shortcut menu. LabVIEW creates a cluster that contains the front panel data.

    7.Right-click the time stamp terminal and select Create»Indicator from the shortcut menu. LabVIEW creates a cluster that contains the time stamp value.

    8.Run the VI. The front panel cluster and time stamp cluster return the data to the front panel of the current VI, according to the record number wired at the input. It also returns a Boolean value that indicates whether the indicated record number is invalid

  • This motor shaft will make 3 rotations, in the same time the output shaft makes 5 Gears used: 20 tooth on motor, 12 tooth on output Gear Ratio: 3:5 Power: 3/5x motor Speed: 5/3x motor (faster)
  • This motor shaft will make 1 rotations, in the same time the output shaft makes 3 Gears used: 24 tooth on motor, 8 tooth on output Gear Ratio: 1:3 Power: 1/3x motor Speed: 3x motor (faster)
  •  
    the bottom two charts are good. It does make it go considerably faster
  •  
    This is probably the best for speed and power(torque). The robot would be front wheel drive based on that if the nxt is on the back with the wheels the robot would flip or slide down due to the weight on the downhill side of the robot not the uphill side(assuming the track is at 22.5 degress

    This shows us the torque of the motor. Yes we have 9 volt batterys, the bottom of the page next to a picture are some gear ratios.

    we could use light snesor to pick up light emitting from the homebase
