HowStuffWorks "Roomba Navigation" | Diigo - 1 views

  •  
    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.
  •  
    I like how this shows all the different types of sensors and where they are, and what path the roomba takes

  • equipped with four infrared Cliff Sensors that prevent robots from falling off stairs or ledges. The Cliff Sensors are located along the inside of the bumper
  • . If the Sensors become obstructed by dust or debris, the infrared signal is weakened

    how cliff detection works and what kind of sensors are used

    this is good to know for when you need to pick a spot to but your sensors

      interesting how it uses the wall following and the spiral, nice demonstration
  •  
    this demonstrates how although it does the cleaning randomly it almost hits every spot eventually

      is it posssible to use at least two of these on the robot, or is there not enough ports on the nxt
    • Thomas Helm
       
      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

How do I use the Roomba Home Base®? - 4 views

  • oomba needs to find the infrared signal of the Home Base in order to return.
  •  
    this is how the roomba finds homebase

Roomba - Wikipedia, the free encyclopedia - 3 views

    • Anthony DiVirgilio
       
      these are some behaviors we could try to program our robots to do
  • generation models have a self-charging homebase they automatically try to find (via its infrared beacons). Charging on the homebase takes about three hours. All second and most third-generation Roombas can be used with the homebase, even if they do not come packaged with it.
  • Four infrared "cliff sensors" on the bottom of the Roomba's bumper prevent it from falling off ledges such as the top steps of stairways. Most second- and third-generation models have internal acoustic-based dirt sensors that allow them to detect particularly dirty spots (zones having excess particulates) and focus on those areas accordingly.

      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
