      This is a way of testing to see if it cleans completely

  • 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)

    very helpful gear ratio chart
  • Joshua Wilkinson on 06 Dec 11
     
    the bottom two charts are good. It does make it go considerably faster
  • Thomas Helm on 07 Dec 11
     
    It looks like a smart idea for designing the wheels maybe it would be possible to adjust it and make it stronger
  • Joshua Wilkinson on 07 Dec 11
     
    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
  • Thaddeus McKeon on 07 Dec 11
     
    I agree wit Josh this is what we need for the project

    this would help our robot detect things from different angle. also, it is more efficient than using a touch sensor with no attachments.
  • Joshua Wilkinson on 17 Oct 11
     
    this works if its driving with the castor wheel in back not the front, it looks like a good idea though
  • Thomas Helm on 17 Oct 11
     
    its actually a pretty nice setup if we found space for the other sensors, but id stick with the back wheel we have now, it also shows how to make it very nicely

    if a light source is detected on the left of the robot, the left motor will speed and the robot will veer away from the light source.increahttp://gicl.cs.drexel.edu/wiki-data/images/7/72/LearningRoomba-SensorsActuators-StudentsGuide.pdfse

  • The Ultrasonic Sensor uses the same scientific principle as bats: it measures distance by calculating the time it takes for a sound wave to hit an object and return – just like an echo

  • fwd holds an advantage in slippery conditions such as ice or snow as more weight is over the drive wheels reducing slip during acceleration
    • Anthony DiVirgilio
      Anthony DiVirgilio on 06 Dec 11
       
      rear wheel drive only has advantages where steering is envloved

    its really opinion but it does seem like a good idea to put it in the front

Sound sensor - 4 views

  • Both LEGO™ NXT sound sensors were placed at the same distance from the speaker. A very simple LabVIEW NXT toolkit was run in debugging mode, in order to display the values on the PC screen and keep the NXT alive (Fig. 3). The frequency and the signal amplitude were gradually changed and the sensor readings were noted manually and entered into an Excel-file and also into a LabVIEW 3D-graph program (that we do not reproduce here). (Fig. 4 and 5) show the different graphs in 3D for the frequencies 100..1000Hz.

  • Declan Coen on 06 Dec 11
     
    this would be a rather complicated idea for our robot but we should figure out a way to have more weight like this one so it stays on the ground. we would need to lower the nxt brick so it does not tip

    this looks good
