Fuzzy Line Following NXT Robot - 5 views

  •  
    One of the tutorials within the Lego Mindstorms NXT Software shows how to program a robot that follows a line using Boolean Logic. In the following, an improved version, based on Fuzzy-Logic, is presented. Although a little bit more complex, the program is still implemented using NXT-G Code.

    this has some good ideas

    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

    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.

    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

Single Sensor « The Roboticist - 4 views

  •  
    In this setup, a single light sensor is positioned on the robot and programmed to follow the outer-edge of a black line. We commonly refer to the robot executing a 'Z' pattern while following the black line.
  •  
    a z pattern might not b the best idea on this because we have a certain time we have to do
  •  
    if we keep it between a very specific max and minimum then it will not zig zag as much and will appear to go straight

Learn LabView: Programming LabView - Shift Register - 3 views

  • As you move forward with LabView programming, you will see that most design patterns are impossible without the shift register. Anytime you are trying to keep track of something in a loop, you will need to use one.
  • The shift register is a key element of LabView programming. It allows looping structures, such as the For and While loop, to carry over values from one iteration into the next. This can be extremely powerful in allowing the developer to build up arrays of information, or retain state information about a program running in a loop.

Robots, mazes, and subsumption architecture - 3 views

  • Wall-following is a simple maze algorithm you might have learned as a child. All you do to solve a maze using this algorithm is keep your left hand on the left wall (or your right hand on the right wall) and just follow it along until you exit the maze. It's easy to see that this algorithm always works if the maze you're in has an entrance and an exit on its border. However, if the goal is within an island — a part of the maze that's disconnected from the rest of the maze — this algorithm can't find a solution because it can't "hop" over to the island.

      this is very helpful for the design
  •  
    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 good way to find the line if you may have fallen off of it.

    this is a good way to make sure you dont lose the line
