    this is a possible way we can program the line folllower excluding the ultrasonic sensor

    you can use the ultra sonic sensor for the maze bot later

HowStuffWorks "Roomba Navigation" - 2 views

  • While Roomba is cleaning, it avoids steps (or any other kind of drop-off) using four infrared sensors on the front underside of the unit. These cliff sensors constantly send out infrared signals, and Roomba expects them to immediately bounce back. If it's approaching a cliff, the signals all of a sudden get lost. This is how Roomba knows to head the other way

      this is how the roomba detects cliffs
  • Roomba can clean for about two hours on a single charge. If you have the self-charger, Roomba will return and connect to the charger all by itself when the battery power is low (the self-charger is sold as an add-on to the Roomba base model but comes included on most of the higher Discovery models). It accomplishes this using the infrared receiver on its front bumper. When the battery power gets low, the vacuum starts looking for the infrared signal emitted by the charger. Once it finds it, Roomba follows the signal and docks itself to the charger. Some robotic vacuums with this self-charging feature will head back out to resume cleaning once they're fully recharged

    this shows why cliiff sensors are needed and how they work

    Another great video for wall detectio using the ultrasonic sensor.
  • Declan Coen on 16 Oct 11
     
    this is a great video because it enables the robot to keep track of the wall it is following and be on the look out for other walls to trace. this could also work for us because we have 3 motors: 2 for drving and turning and 1 for the ultra- sonic sensor

    When Roomba knocks into something, its bumper retracts, activating mechanical object sensors that tell Roomba it has encountered an obstacle. It then performs (and repeats) the sequential actions of backing up, rotating and moving forward until it finds a clear path.
  • Thomas Corcoran on 13 Oct 11
     
    I like how this shows all the different types of sensors and where they are, and what path the roomba takes

    the robot designs on this page are possible for our criteria. the majority of them have a ramp like structure on the front for pushing and flipping

    the ramp on the front seems to be the easiest way to win based on other designs ive seen.
  • Alexander Laferriere on 17 May 12
     
    this has some good ideas

    i wish i could see some of the videos but i cant right now i wanted to see if thee were any changes to ramp in general

  • light sensor moved towards, and then away, from the line edge, (and then again towards, and then away, and so on…) as shown in the two photos below.

    I know we don't have 2 light sensors but it is nice to know one way of doing it

  • 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.

    i think that this is a great idea
  • Declan Coen on 05 Apr 12
     
    this would probably work very well and if we added a touch sensor *i dont know if they had one* which would activate the ultrasonic sensor and it would search and pick a path
  • Thomas Helm on 05 Apr 12
     
    That was a good idea declan thanks buddy
