      the wall following robot is much more efficient in its cleaning

    very good demenstartion and helped me understand how the wall detection move
  • Declan Coen on 13 Oct 11
     
    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.

  • The most common kind of robot failure is not mechanical or electronic failure but rather failure of the software that controls the robot.

  • 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

  • Declan Coen on 16 Oct 11
     
    this is a good design for our robot because it has the sensor on the side for wall following and it has a touch sensor on the front which tells it to turn

    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

    many sample codes for different reasons
  • Declan Coen on 16 Oct 11
     
    they are good codes because we can use them to help the robot carry out specific functions. also they are much simpler than the long codes that we have to make so in the long run these codes will make it easier and it will save us time

    this shows why using the tutch sensor is a good idea to detect walls
  • Declan Coen on 16 Oct 11
     
    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

      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
