  • 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

    I agree wit Josh this is what we need for the project

    This is like a calculator you insert the gear it gives you the ratio
  • Declan Coen on 06 Dec 11
     
    this is very useful in helping us decide which gears to use and what ratio to set them at
  • Joshua Wilkinson on 06 Dec 11
     
    This might be the key thing for gear ratios

    the robot designs on this page are possible for our criteria. the majority of them have a ramp like structure on the front for pushing and flipping

    the ramp on the front seems to be the easiest way to win based on other designs ive seen.

Rear wheel drive vs. front wheel drive. Which is better? - 8 views

shared by Anthony DiVirgilio on 06 Dec 11 - No Cached
  • 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
    • Bryan Kelleher

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

    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

Logging Front Panel Data - NI LabVIEW 8.6 Help - 6 views

  • Declan Coen on 25 Jan 12
     
    Shows how datalogging works
  • Thomas Helm on 26 Jan 12
     
    Use front panel datalogging to record data for use in other VIs and in reports. For example, you can log data from a graph and use that data in another graph in a separate VI. Each time a VI runs, front panel datalogging saves the front panel data to a separate datalog file, which is in the format of delimited text.

  • Declan Coen on 05 Apr 12
     
    this would probably work very well and if we added a touch sensor *i dont know if they had one* which would activate the ultrasonic sensor and it would search and pick a path

    this is a good idea but it would be hard to change the gears in a short amount of time
  • Declan Coen on 06 Dec 11
     
    this might be a possible solution but it might not have enough power to make it up the 22.5 degree incline.

    this could work but what if the robot turned and started going the wrong direction back towards the start???? it only follows the walls which could lead the robot back to the start not the finish
  • Thomas Helm on 05 Apr 12
     
    anyrobot we do is basically going to be folllowing the wall though and it would have to go all the way to the end to start going back to the beginning

  • Thaddeus McKeon on 02 Apr 12
     
    I feel the way they set up the light sensor is a little to far out
  • Joshua Wilkinson on 02 Apr 12
     
    we are gonna have to place the ultrasound or light sensor under three inches if we are following the inside walls, but thats an individule decsion. we could use a code similar to the wall following code in the romba project.
