isnt the front gonna be a wedge anyway, how would be easier to flip?

  • 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
  •  
    the bottom two charts are good. It does make it go considerably faster
  •  
    It looks like a smart idea for designing the wheels maybe it would be possible to adjust it and make it stronger
  •  
    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 has some good ideas

it would work on the other tracks if the robot dosent drive off the line a lot.

      thats the best ratio i could find for the tools we have
  •  
    this is good to show what gears to use

    This is like a calculator you insert the gear it gives you the ratio
  •  
    this is very useful in helping us decide which gears to use and what ratio to set them at
  •  
    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
  • ...3 more comments...
  •  
    the ramp on the front seems to be the easiest way to win based on other designs ive seen.
  •  
    this has some good ideas
  •  
    the terminator looks like a fun approach to this project
  •  
    i wish i could see some of the videos but i cant right now i wanted to see if thee were any changes to ramp in general
  •  
    the sumobotofdestruction looks cool and doable

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

  • 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
       
      rear wheel drive only has advantages where steering is envloved
    • Bryan Kelleher
       
      AGREED, BUT ARE WE GOING FOR PURE STEERING? OR POWER?!
  •  
    this could be useful
  • ...3 more comments...
  •  
    its really opinion but it does seem like a good idea to put it in the front
  •  
    This could be very helpful for gear changing
  •  
    these are real cars not NXTs
  •  
    thanks for pointing that out, i didnt want to say anything
  •  
    it doesn't matter the theory is sound

    ^ this show an idea we can use for backing up when objects contact our nxt
  • ...2 more comments...
  •  
    this would help our robot detect things from different angle. also, it is more efficient than using a touch sensor with no attachments.
  •  
    this works if its driving with the castor wheel in back not the front, it looks like a good idea though
  •  
    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

  • A waveform chart logs only one data point at a time with front panel datalogging

  • subset of the array the chart displays.
  •  
    Shows how datalogging works
  •  
    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.

  •  
    i think that this is a great idea
  •  
    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
  •  
    That was a good idea declan thanks buddy
  •  
    OK 0_0

    sorta of a change in design than the last one i had thought was good
  • ...3 more comments...
  •  
    this looks like it wikll work
  •  
    this is a good idea but it would be hard to change the gears in a short amount of time
  •  
    this might be a possible solution but it might not have enough power to make it up the 22.5 degree incline.
  •  
    looks good
  •  
    Great pictures Tommy. We can use some of these ideas to build our robot

datalogging and suchh. - 5 views

  • The basic idea of datalogging is to run an experiment, but have a computer do the tedious data recording for you. For instance, if you wanted to know how the temperature changes during the course of an entire day, you

Light sensor and Ultrasonic thats it - 4 views

  •  
    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
  •  
    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

  •  
    the way the ultra sonic sensor is set up is a good idea
  •  
    I feel the way they set up the light sensor is a little to far out
  •  
    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.
