    good for sound sensor

    it measures the sound at different locations and different distances

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.

      we could use this to make the user have to do less to use the robot

    this is helpful

    This shows how the sensor will detect sound and then transmit it to the nxt

    THIS WAS EXTREMELY HELPFUL

    we could use this logic, when the sound sensor detects the sound indicating the start of the race that would be the starting condition for the program ps. i know that we do not use the same programming as in the picture
  •  
    But what if people are speaking? you would have to set it to a certain frequency.

    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.
  •  
    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

    i thing that this proves that a big plow in the front may be a good idea
  •  
    Jarid had posted a link as well with the plow as a v shape. this would work if your going for pushing someone off the table

    this shows that the robots will be better at pushing if that have alot of torque
  •  
    shows a great example of an inclined plane

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

    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 looks good
  •  
    this is not very helpful. we already know about the sensors
  •  
    Ya i agree we dont need to know about the sensors

    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

    this is a good thing to look AT

    Great idea Tommy. This could be very useful later in the project

NXT Data Collection - NI Discussion Forums - 3 views

  • sounds like for your application you might want to use the Log Angle (red/blue/green) nodes to acquire your data. This lets you sample at a specific rate for a given amount of time and saves the data to a file called RedData.dat, BlueData.dat or GreenData.dat depending on the color of the Log Angle you chose

  • 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

      is it posssible to use at least two of these on the robot, or is there not enough ports on the nxt
    • Thomas Helm
       
      im very sure that you can use more than one sensor but ill see if i an find something on it now
  • The Touch Sensor reacts to touch and release, enabling your LEGO® MINDSTORMS® NXT robotic creation to "feel" like never before! It can detect single or multiple button presses, and reports back to the NXT Intelligent Brick
