There are so many Simple Bots that sweep and scrub, that I felt it only appropriate to make one that picks up after them. Scoop does just that. It pushes itself around and systematically scoops up whatever lies in its path. Well... maybe "systematically" is too strong of a word to use in describing it, but it definitely gets an A+ for effort. If there is one thing that Scoop Bot wants to do more than anything else in this world, that is scoop. There is not a man, woman, ice cream server, or investigative journalist alive, quite as dedicated to scooping.

How do you program it? I didn't see anything for that purpose
randofo (author)  Ouranos10 months ago
No programming involved.

You could add a PING)) ultrasonic sensor so that it can automatically scoop without bumping and breaking stuff.
You should do a video instructable on your "studio" where you make these instructables. Your pictures are always really good with that white background.

Nice and clever design, Randy.

For more money you could add an ultrasonic range finder and an uno and that would be more efficient? Or program it to follow a specified course, but that would be about $70 more?

Nice thing!
What tool did you use to create the video?
randofo (author)  hertzgamma2 years ago
Quicktime Pro and Photoshop. Its not ideal but gets the job done.

Beautiful presentation! Dare I say... elegant. OK it's not something I plan to use, but the concepts can be useful for other stuff. I look forward to seeing your other work. Thank you for posting what looks like the cleanest presentation I've seen on the whole site. Keep up your good work!
Great!

For a moment I was a fraid this was actually going to be a practical and usefull bot, which would kind of ruin the fun for me ;-).

Great project and great Ible!
This is the cleanest instructable i have seen, very nice!
