Navigating to Wapoints without GPS?

Posted by Elvis on December 26, 2012 at 9:23am

I have a unique situation where I want a rover to navigate to waypoints without the aid of a GPS. Would this be possible? Maybe through use of other sensors... accelerometer, sonar, etc...?

This is for an educational project where GPS nav is not allowed.

Thanks,

Elvis

    @Elvis,

    Everything that you have ever wanted to know about navigating to waypoints with GPS as a last resort: http://www.geology.smu.edu/dpa-www/robo/jbot/index.html

    don't know if i used the correct term, but basically it's using software to recognize objects. it is not a trivial solution, but it may be worth looking into

    good luck

    if you're familiar with computer vision, that may be an avenue to explore if you have unique landmarks

    i'm also sure there are GPS-like systems available which are ground-based systems - so you have some transmitters and a Rx and you triangulate position

    another possibility may be the cellular networks - i think they use AGPS - assisted GPS - whereby you calc position based on nearby towers

    what about line following? can you lay a string for the rover to follow?

    If you're on flat pavement and add wheel encoders, you can use dead reckoning for short periods of time before it diverges too much from reality without GPS.
