  • 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

    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.

  • 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

      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

    very good demenstartion and helped me understand how the wall detection move
  • Declan Coen on 13 Oct 11
     
    it helps show how the robot will travel until it reaches a wall to clean. Then from there it continues to travel along the wall until it is clean. Also, it helps show the perimeter of the room.

    this shows why using the tutch sensor is a good idea to detect walls
  • Declan Coen on 16 Oct 11
     
    it seems that the robot is using a sensor on top of itself. this can be helpful because it can detect cilffs faster but it will detect them too soon and turn away. therefore, it won't clean everything. in my opinion we should place the sesors in front and not on the top
