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

    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

    LabVIEW 2009 LEGO MINDSTORMS NXT Module Help When using loops, it is often useful to have a result from the last iteration of the loop for the next iteration of the loop. This can be accomplished using Shift Registers; shift registers will pass values from previous iterations through the loop to the next iteration.

  • 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

  • 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.

obstacle

shared by Thomas Corcoran on 17 Oct 11 - No Cached
  • In this study, a path correction and obstacle avoidance method for a bipedal intelligent robot, using an ultrasonic sensor and electronic compass sensor, is proposed. The proposed method is implemented on an autonomous humanoid robot (the ARSR) comprised by the Lego NXT Intelligent Bricks. One ultrasonic sensor and one electronic compass sensor are installed on the ARSR to detect environmental information including obstacles, the distance to the obstacle, and the directional angle of the robot. Based on the obtained information, an obstacle avoidance and path correcting method is proposed to decide the ARSR’s behavior so that it can avoid obstacles automatically and move effectively to the destination area. Three obstacle avoidance experiments are carried out to confirm the effectiveness of the proposed method.
