 How to build an advanced line follower robot?
Hi all! I am a beginner in Robotics ... But I have no experience in building this kind of robots ( Advanced line follower robot)... I have a robotics contest on 7th Of august in the field of advanced line follower robots ... Can you help me? I need Some Sites about how to build these robots & ... I want to win the contest... please help me if you can... Thanks. Last edited by Sam Fisher; 10th July 2009 at 07:32 PM. | |

What makes an advanced line follower better than a typical line follower? PS Experience = Win Last edited by blueroomelectronics; 7th July 2009 at 07:57 PM. | |

Well , you don't have an article in this case?  I can't do some changes in the typical robot structure that convert it into advanced ? Well ... I don't think that the structure of an advanced line follower robot is very complex.. Thanks. Last edited by Sam Fisher; 8th July 2009 at 07:32 AM. | |

Hi there... Here is a Cool Forum! I love it!... I have a question: Working with which sensor is easier? Photocell or IR sensor? Thanks. | |

There are many types of both, but short answer theyre about the same difficulty except if you use visible light...you can see it. One tip I can give you is that you can get most of these parts from a broken printer, which are usually easy to find. They have motors and gears for controlled pacing, steppers, DC brushed or both. They often have led/sensor pairs which they use to track how far they've moved. And you may be able to salvage some good connector cables, complete with sockets, motor control parts, buttons, resistors and other such stuff. Since a printer already is a robot that detects lines and controls motors, you might have everything you need. | |

Hi, Which do you choose to start? Which is easier to start to building a robot? AVR or PIC ?

There are supporters of both, I chose PIC, there are a lot of PIC users here, and I've found tutorials on them can be found easily, if you choose AVR there is support for that, but you would probably want to go to a forum for that like AVRfreaks. Theres also the paralax propeller, all I know about it is that it has eight cores, it uses co processing instead of interrupts, and that it has its own community of hobbiests as well, no one really talks about those chips here either. If you go with PIC just go ahead and start with the PIC18F series, for some reason someone I know told me that the lower numbers were easier. So I started with them, it turns out thats like saying a commodore 64 is easier to use than a modern PC. Sure its got more in it, but thats just more stuff to make it useable. I've switched to 18F chips, and haven't had much use for the 16F and 12F stuff I got since. 18F chips have been way easier to use. | |

At this rate you'll never be ready by August. Most line followers don't have a CPU, you should start with your chassis and sensors and worry about the logic after that.

Does it define in the rules what is meant by "advanced" line follower?

After each change, at least 20 cm is the direct route. there may be one or more closed loop or path with a minimum angle of 10 degrees to the horizontal line:  Errors: 1. Contact robot with a red line border with 20 cm distance on both sides of the main line . 2. Revolve around , although the mainstream and return again to the line. 3. Any physical stimulation during the Robot Competition during (lift wire, contact hand with the robot and ..) 4. Start earlier than the referee announced. Competition land dimensions are 180 × 300 cm These rules were summarized total... One person told me that use tcrt5000 sensors... If you need more informations post it here... Thanks.

Is the contest August 7 2010 or 2009? How big is your budget? How will you get the parts you need in time? How do you plan to test your design before the contest? | |
