touch sensor - 1 views

  •  
    this shows why using the tutch sensor is a good idea to detect walls
  •  
    it seems that the robot is using a sensor on top of itself. this can be helpful because it can detect cilffs faster but it will detect them too soon and turn away. therefore, it won't clean everything. in my opinion we should place the sesors in front and not on the top

Long-Exposure Shot of a Roomba's Path Shows Beautifully Organized Chaos - 3 views

      shows that the roomba isnt as smart as people think it is, but more uses its random feature
  • while cleaning up. It's beautiful and surprising. I always assumed it worked with using some sort of grid, but that clearly isn't the case at all

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

    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

  • oomba needs to find the infrared signal of the Home Base in order to return.

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.
