Autonomous rover roams the halls

[ESylin] built an autonomous rover that roams the vacant halls of his school. On the hood of the vehicle he’s mounted two Maxbotix sonar sensors that do a great job of keeping the vehicle centered in the hallway. It will follow a wall around a corner (favoring its left side because of the left-facing sensor) and it will stop to correct itself if it gets off course. That’s because when you’re not driving a dsPIC33 is, with a Traxxas XL-5 speed controller and a hobby servo for steering. But this little guy hasn’t lost all his pep. Manual control and be switched on from from an R/C controller so you can burn up the floor tiles. Take a look at the demo after the break, with the manual control demo shown at about 4:10.

    Is anybody else thinking of the tiny robot from the Death Star?

    @nimiz: it just needs to move a bit faster and have a mic so it can respont to loud roars ;-)

    It looks like a Toyota Scion XB to me. But yes, I as thinking the same thing.

    Is it just me or was this post totally unintelligible?

    “Manual control and be switched on from from…”

    I don’t even know what he thought he was saying.

    I didn’t even notice that until you mentioned it. Seeing the typos reminds me we are all still human… for now.

    I think one of his brakelights are out.

    It should go faster, and the KITT lights should go a little faster

    what happens when it comes to a dead end hallway? will it turn around on its own?

  10. ESylin says:

    willy, it does has some code to deal with dead ends. it takes measurements when it comes to a stop. It will work its way out of a dead end or corner.

    the speed unfortunately was regulated by the update speed of the sonar sensors. I tried going faster, but it didn’t end well.

    it seems to do a good job of smoothly passing the open doors and other disruptions that are not the corners.
