L.I.O.S.: The ten-ish dollar robot.

We love cheap stuff here. Who doesn’t? [Oscar Rodriguez Parra] does too, and wrote in to show us his super cheapey robot L.I.O.S. The build was for the AFRON design challenge, which involves building a 10 dollar robot to teach students robotics. The winners of the challenge were neat and all, but they all look too fancy flaunting their molded plastics and electronics breadboards.

[Oscar's] design is super simple, LDRs as eyes, a PIC12F683 to do the brainin, LEDs for indicators and a couple modded servos to drive the wheels. An extraordinarily complex cardboard flap roller helps the cart turn, but probably isn’t going to see much aside from smooth flooring. The electronics are mounted using one of our favorite techniques, the paper perf board (very similar to the substrate free technique).

Check out the video after the jump to see LIOS in action. This is an excellent introduction to robotics for any classroom. Thanks [Oscar]!

Bots 4 tots charity launched

Bots 4 Tots

If you feel the same way that we do about robotics, you probably wish that you had more experience with them when you were a kid. [Don] felt that way too, and he decided to do something about it. So [Don] and his partner started the Chicago based organization Bots 4 Tots, with the mission of introducing inner city kids to robotics. [Don] told us that his organization plans on starting the kids with snap together projects like OWI’s Jungle Robot. After a few snap together projects, they plan to introduce the kids to soldering and hope to eventually move on to a larger collaborative project that all the kids can work on. Of course, doing all of these things requires money. Thats where we, as the DIY community, come in. So feel free to hit up the Bots 4 Tots site and make a donation to support their worthwhile cause, we know we will.
