      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.

Sound sensor - 4 views

  • Both LEGO™ NXT sound sensors were placed at the same distance from the speaker. A very simple LabVIEW NXT toolkit was run in debugging mode, in order to display the values on the PC screen and keep the NXT alive (Fig. 3). The frequency and the signal amplitude were gradually changed and the sensor readings were noted manually and entered into an Excel-file and also into a LabVIEW 3D-graph program (that we do not reproduce here). (Fig. 4 and 5) show the different graphs in 3D for the frequencies 100..1000Hz.

      we could use this to make the user have to do less to use the robot

    This shows how the sensor will detect sound and then transmit it to the nxt

    THIS WAS EXTREMELY HELPFUL

Wall Follower - Top View - YouTube - 2 views

  •  
    Another great video for wall detectio using the ultrasonic sensor.
  •  
    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

What are Roomba Virtual Wall Lighthouses™? - 3 views

      Shows how the virual wall works with the senson on the robot before it get to the avoided area

    thank you for this link could not find one

    this shows the wall following in action
  •  
    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

    these people placed the ultra sonic sensor on the front so the robot will never lose trsc of the wall

    ^ this show an idea we can use for backing up when objects contact our nxt

  •  
    this would help our robot detect things from different angle. also, it is more efficient than using a touch sensor with no attachments.
  •  
    this works if its driving with the castor wheel in back not the front, it looks like a good idea though
  •  
    its actually a pretty nice setup if we found space for the other sensors, but id stick with the back wheel we have now, it also shows how to make it very nicely
