Maze solving algorithm - Wikipedia, the free encyclopedia - 1 views

  • mazes, is also known as either the left-hand rule or the right-hand rule. If the maze is simply connected, that is, all its walls are connected together or to the maze's outer boundary, then by keeping one hand in contact with one wall of the maze the player is guaranteed not to get lost and will reach a different exit if there is one; otherwise, he or she will return to the entrance.

    has good techniques
  •  
    this would work really well but it might take more than 60 sec

    I know it doesn't say much but this single-motored nxt can rotate it's ultrasonic sensor allowing it to see multiple walls at once

      useful for different configurations, good to know
  •  
    This shows us the torque of the motor. Yes we have 9 volt batterys, the bottom of the page next to a picture are some gear ratios.
  •  
    it shows how we can adjust the gear ratios to give the robot more or less power while driving

      this is the important chart from the website
  •  
    good for setting up our ratios

wall following - 4 views

  •  
    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

  • 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

      this is a good idea to get the most out of our gears

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

  •  
    new take on the wedge design
  •  
    it might just push them off to the side which has some effect but it doesn't provide much offense
  •  
    we could invert the v so the point where the blades come together is where it would get caught.

    i thing that this proves that a big plow in the front may be a good idea
  •  
    Jarid had posted a link as well with the plow as a v shape. this would work if your going for pushing someone off the table

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.

How Can I Make a Sumo-bot? - 3 views

  • No sumo-bot is perfect; this means that sumo-bots that I make and that you     make will have "problems" or "weak-spots."

    i don't see how that robot can go on the offensive side
