      thats the best ratio i could find for the tools we have
  • Alexander Laferriere on 06 Dec 11
     
    this is good to show what gears to use

    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

  • 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)

    great ideas for gear ratios

    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
  • Alexander Laferriere on 07 Dec 11
     
    this has some good ideas

      this is the important chart from the website

    good for setting up our ratios

    It is too big for the track
  • Thaddeus McKeon on 07 Dec 11
     
    shows how to make a big NXT dragster but has some stuff about gear ratios in it
  • Bryan Kelleher on 07 Dec 11
     
    FITZGERALD, THIS IS A GOOD IDEA I THINK WE SHOULD USE IT

  • 10:30:40 = 1:4 9:27 = 1:3 10:20 = 1:2 10:13:20 = 1:2 Overall 1:48

      useful for different configurations, good to know
  • Joshua Wilkinson on 06 Dec 11
     
    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.
  • Declan Coen on 06 Dec 11
     
    it shows how we can adjust the gear ratios to give the robot more or less power while driving

Great steps for gear ratios.Ideas for changing the gear ratios faster?

      very helpful and useful
  • Declan Coen on 06 Dec 11
     
    The bottom of this page explains how to create differnent gear ratios and how they work
  • Alexander Laferriere on 06 Dec 11
     
    they are using a diffrent program
  • Joshua Wilkinson on 06 Dec 11
     
    we could make the program in labview, they were just using a piece of wood on books.
