[Niklas Roy] sent in probably one of the largest line following robots ever built. The Gallerydrive project is used to move visitors around an art gallery. It can follow either a black or white line. It also has a touchscreen display for displaying information about the art which is read from RFID tags. Niklas has a full diary of the build on his site with everything you need to build your own.
Excellent work! This is a great hack. It has everything… motor drivers, touch screen displays, audio and best of all lasers. I tend to agree with Niklas that using FET followers on a linear regulator is not a great idea. They go bang very easily. Stick with switching regulators.
An interesting robot. i use to work as a programmer at oak Ridge National Labs and they had a mail delivery robot. It would follow the lines around the building and stop outside your door and beep a few times to tell you that you had mail. It is not as sophisticated as this robot but was built along time ago. I left the Lab in 1994 and it was old then.
Aha! Nice job sneaking this hack in at 11:59.
I work at a school for kids with disabilities and something like this would be a great way to move a dozen or so wheel-chair bound kinds from one classroom to another.
Awesomeness ! Full schematics, well done diary, source code, software simulator, etc. What a great project!
Andrew, you might have a problem with them ramming each other.
@halz – my first thought was black electrical tape into the wall. why do i have evil thoughts?
i have to say, this is really well done. i admire!
This is a great hack. It’s clever and involves a lot but best of all, it’s useful and has a great purpose. Nice one to include
I could see a nursing home cut their staff by making a permanent black tiled “racetrack”. You load granny in the chair start her on her way. Then you pop old grandpa right behind her -boy -girl -boy -girl (to make the view more interesting for them) and they can run around the go-cart track all day long. Wheee!!! Just hope the batteries hold out. If you tape off the parking lot the whole gang could have fun in the sun.
Sorry I can’t see anything, would somebody tell me why, the original page doesn’t works.
Hack a Day serves up fresh hacks each day, every day from around the web as well as hacking related news.
Oh the fun you could have with a marker pen or some black/white electrical tape at that museum.
