Thinking about entering Trinity College Fire-Fighting Contest

     The Trinity College Fire-Fighting Contest is the closest competition (to me) I know about, has anyone else considered entering?   In about a month registration opens and I was thinking of entering this year.  (definitely will enter next year)

There home page is:  http://www.trincoll.edu/events/robot/

And the rules are here : http://www.trincoll.edu/events/robot/Rules/default.asp

TinySpider

May I introduce myself, I am TinySpider. I was build a couple of days ago after my creator got some ATTiny and needed to try them out. I was inspired by this  http://www.instructables.com/id/Computer-Bugs-Additional-Ideas-Tips-Tricks/step15/4-Spider/  

Basically I am a bare ATTiny85 some copper wire, two LED's and one 3.7V/50mAh LiPo battery.

ATTiny programmer shield

I got some ATTiny and now need to transfer the program from the Arduino IDE to the ATTiny without a programmer.

The solution is, just make your own programmer shield. Based on this tutorial http://hlt.media.mit.edu/?p=1229 I created my programmer shield for the Arduino Duemilanove. It's not pretty since it's just a ugly board out of my box but it works. Preparing the Arduino duemilanove according to this tutorial and then hook up the ATTiny into the header pin socket, open your sketch and click upload. Done!!!

Anyone know about machine learning on Arduino?

I saw this code about Neural net on an Arduino here: http://robotics.hobbizine.com/arduinoann.html

and would like to know how I could apply it to my latest robot DuckBot so that it could figure out how get back on it's feet

on it's own instead of me having to code explcitely to do that. I have one sensor that currently says if angle of sensor indicates < 145 degrees then robot has fallen. It uses 3 servos to get back up on its feet.

Any ideas greatly appreciated.

Quadruped Sneak Peak!

In the Grapes of Wrath, there was a turtle that had a lot of symbolism, and in English class, you can basically do anything for the final project. So I thought, what the heck, I'll just play my strengths! Below is a rough CAD using 3d-printed parts and MG996R servos. Electronics are not really shown, shell is not missing (like there's a CAD of a salad bowl out there), and the head has been remodified to have a more "turtle" look. Photos of the final product coming soon.
