obstacle avoidance - 5 views

  • In this study, a path correction and obstacle avoidance method for a bipedal intelligent robot, using an ultrasonic sensor and electronic compass sensor, is proposed. The proposed method is implemented on an autonomous humanoid robot (the ARSR) comprised by the Lego NXT Intelligent Bricks. One ultrasonic sensor and one electronic compass sensor are installed on the ARSR to detect environmental information including obstacles, the distance to the obstacle, and the directional angle of the robot. Based on the obtained information, an obstacle avoidance and path correcting method is proposed to decide the ARSR’s behavior so that it can avoid obstacles automatically and move effectively to the destination area. Three obstacle avoidance experiments are carried out to confirm the effectiveness of the proposed method.

    I think this is a good idea!

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

    the robot designs on this page are possible for our criteria. the majority of them have a ramp like structure on the front for pushing and flipping

  •  
    the ramp on the front seems to be the easiest way to win based on other designs ive seen.
  •  
    this has some good ideas
  •  
    the terminator looks like a fun approach to this project
  •  
    i wish i could see some of the videos but i cant right now i wanted to see if thee were any changes to ramp in general
  •  
    the sumobotofdestruction looks cool and doable

    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

    this shows that the robots will be better at pushing if that have alot of torque
  •  
    shows a great example of an inclined plane

    sorta of a change in design than the last one i had thought was good
  • ...3 more comments...
  •  
    this looks like it wikll work
  •  
    this is a good idea but it would be hard to change the gears in a short amount of time
  •  
    this might be a possible solution but it might not have enough power to make it up the 22.5 degree incline.
  •  
    looks good
  •  
    Great pictures Tommy. We can use some of these ideas to build our robot

    • Thaddeus McKeon
       
      also shows how to program in a different version though
  • Adding a vertical ultrasonic sensor to ClareBot allows the robot to go around an arena without touching the walls
  •  
    shows how to build a simple wall following robot
  •  
    Although this is an older version, the placement of the Ultra sonic sensor is a good thought

      the wall following robot is much more efficient in its cleaning
    • Thomas Helm
       
      it shows how it knows what to do near a wall
  •  
    great video for wall detection and how the robot will make its way through obstacles.

    very good demenstartion and helped me understand how the wall detection move
  •  
    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.
  •  
    it looks like the grey one has something wrong with it

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

    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
