  • fwd holds an advantage in slippery conditions such as ice or snow as more weight is over the drive wheels reducing slip during acceleration

      rear wheel drive only has advantages where steering is envloved

      AGREED, BUT ARE WE GOING FOR PURE STEERING? OR POWER?!

    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

  • 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.

    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 is a simple dual worm gear drive. It turns two turntables using two worm gears spinning in the same direction at the same speed using one motor. It was really quite easy to build.

    we could make the program in labview, they were just using a piece of wood on books.

    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

    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.

  • First....What is torque?: Torque is a twisting force- (it doesn't do any 'work' itself- it is simple an application of energy). Work (or 'stuff') happens, when torque is applied and movement occurs.
