    this looks very useful and easy to add to what we allready have
  •  
    there are touch sensors on the front which are attached to angled levers which help the robot detect objects from different angles

Line Follower - LabVIEW for Lego MINDSTORMS Projects - 3 views

  • 3. In case the lighting in the room changes, could you program your line follower to re-calibrate the light sensor when you push a button?

      could b useful later on to look into

    Tufts University Center for Engineering Education and Outreach In this activity, we will learn how to create a robot that follows a line on the ground. It will use one light sensor to sense where the line is, and use this to control the motors to steer the car and stay on the line.

Passing Data Between Loop Iterations in NI LabVIEW - National Instruments - 2 views

  •  
    When programming with loops, you often must access data from previous iterations of the loop in LabVIEW. For example, if you are acquiring one piece of data in each iteration of a loop and must average every five pieces of data, you must retain the data from previous iterations of the loop.

iRobot - cliff detection - YouTube - 2 views

    • Anthony DiVirgilio
       
      This is a good video to show how the cliff detection works
  •  
    it shows how the roomba uses the infared sensors to detect cliffs and dropoffs. the robot expects to recieve signals from the floor and if the signals take too long to get back to the robot such as driving over stairs, the roomba will stop and go in a different direction

NXT Forklift - 6 views

  •  
    this is a great idea because it is effective and we can use fishing line in place of the string. Our fork lift would have to be wider though.
  •  
    also shows how to make a bluetooth connection very doable to

NXT Line Follower - 2 views

  • When line following, the robot will try to align itself centered over the boundary between white and black (not centered over the black line), with black to the robot's left.  Here the brightness seen by the sensor is halfway between the black/min and white/max readings
    • Joshua Wilkinson
       
      This would be useful since we get the value when its over the tape and table, we can also find the value of the sensor when its directly over the tape then the table seperately.
  • When prompted to sample the "Min" or "Black" reading, position the sensor so that the red spot is centered over the line and then press the Enter button on the NXT. When prompted to sample the "Max" or "White" reading, position the sensor so that the red spot is completely over the surface away from the line and press the Enter button on the NXT.
  •  
    Before line following using either the LineFollow2 or LineFollow5 program, you should "calibrate" the light sensor to the actual conditions expected. With the sensor mounted on the robot where it will be used, and the robot placed over the actual line it will be following, a calibration process takes two light sensor readings, one directly over the line (minimum = darkest), and one over the surface away from the line (maximum = brightest).
  •  
    if we follow the edge of the line we will always be between the max and the minimum values. therefore, it can detect both values and stay between the min and the max.
  •  
    we have to figure out how to correctly calibrate the sensors

Using Shift Registers - 1 views

  •  
    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.

Maze solving algorithm - Wikipedia, the free encyclopedia - 1 views

  • mazes, is also known as either the left-hand rule or the right-hand rule. If the maze is simply connected, that is, all its walls are connected together or to the maze's outer boundary, then by keeping one hand in contact with one wall of the maze the player is guaranteed not to get lost and will reach a different exit if there is one; otherwise, he or she will return to the entrance.

    has good techniques

    this would work really well but it might take more than 60 sec

obstacle avoidance - 5 views

  • 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.

      the wall following robot is much more efficient in its cleaning

      it shows how it knows what to do near a wall
  •  
    great video for wall detection and how the robot will make its way through obstacles.
  • ...1 more comment...
  •  
    very good demenstartion and helped me understand how the wall detection move
  •  
    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.

    it looks like the grey one has something wrong with it
