Mustachioed Rover Simultaneously Manly, Adorable

[Rick], an Adafruit learning system contributor, is excited by the implications of STEM’s reach into K-12 education. He was inspired to design Red Rover, a low-cost robot that can be easily replicated by anyone with access to a 3-D printer.

This adorable autonomous rover is based on the adafruit Trinket microcontroller, but will also rove under the power of an Arduino micro. It really is quite simple—the Trinket drives two continuous rotation micro servos and pretty much any flavor of rangefinder you like. [Rick] tested it with Parallax PING))), Maxbotix, and Grove sensors, and they all worked just fine.

What’s truly awesome about Red Rover are the track treads. [Rick] initially experimented with flexible filament. While he had good results, it was not a cost-effective solution. What you see in the picture and the short video after the break are actually rubber bracelets from Oriental Trading.

The plastic part count comes in at seven, all of which can be printed together at once. [Rick]‘s gallery includes both small and large chassis and three different servo mounts. The Red Rover guide builds on other adafruit guides for Trinket general use, servo modification, and Trinket-specific servo control.

Update: Added [Rick]‘s demo video after the break!

Crazy Holidays Extra


After sushi-thanksgiving at my house, I’m beat – but you guys have been busy on the tips line.

In one of those special moments of vengance, the ‘real’ ps3 grill was created. (It’s been built, don’t be fooled by the fund raising graphic they were too lazy to remove.)

In another moment of consumer electronics death, a 25mw 405nm laser was obtained from a blu-ray DVD burner and turned into the closest thing to a light saber I’ve seen.

[James Coxon] sent in his autonomous RC car project. I found his Pegasus high altitude balloon project even more interesting.

If you haven’t already heard about it, if you can hack this ps3, you’ll actually get to own it. Thanks [good4me] and [wierdguy].

[Chris_rybitski] sent in his music syncro’d christmas light control – he runs the AC audio into diode rectifier to drive a SSR.

If you really hate squirells, [Alexiy] thinkgs you might find a remote controlled airsoft gun handy.

Don’t forget to check out the Hack-A-Day Design Challenge. I already announced the iPod, the MAKE controller and Daisy MP3 player kit, but look for another prize announcement soon.

Let the holiday geekery continue!
