      thats the best ratio i could find for the tools we have
  •  
    this is good to show what gears to use

    This is like a calculator you insert the gear it gives you the ratio
  •  
    this is very useful in helping us decide which gears to use and what ratio to set them at
  •  
    This might be the key thing for gear ratios

    we could use this logic, when the sound sensor detects the sound indicating the start of the race that would be the starting condition for the program ps. i know that we do not use the same programming as in the picture
  •  
    But what if people are speaking? you would have to set it to a certain frequency.

Ultrasonic Senesor? - 4 views

Maybe, we could put the ultrasonic sensor on the NXT. We could put our fingers in front of the sensor right before the race would start. We could program the ultrasonic to go when our fingers are ...

      could be really fun to build

      Great info
  •  
    gears and construction on how to get high speeds
  •  
    This wouldn't work going up hill at 22.5 degress, and how would we get the nxt brick and the rest of the body to move that fast??

    this is helpful for creating less complicated block diagrams

    This is really good to know for when everything starts to get really crazy

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.

    what to use for obstacle avoidance
  •  
    I think this is a good idea!

      could pivot constantly, almost like radar

    this looks very useful and easy to add to what we allready have
  •  
    there are touch sensors on the front which are attached to angled levers which help the robot detect objects from different angles

  • The Roomba Remote, Virtual Wall, and Home Base operate using an invisible infrared technology.

    we could use light snesor to pick up light emitting from the homebase
