Experimental RC Robotic Hand

Introducing my Experimental RC Robotic Hand. I'm going to use it for a robot that I will use to take on Ro-bot-X's "Search And Rescue" Challenge. It's purpose is to get a hold on the drink, obviously. This is only Version 0.2, I'm am currently building a lighter and easier to use grabber to replace the heavier hand that is attached to the winch motor.  More updates soon.

Propeller Survey Program

Yes or No... thats the only answer on my program. After several months of school I finally decided to make another fun program. Success! I was sitting there trying to think when I thought about all the tests I have this week... and there was my idea. I thought that I should create a program that askes questions you must answer. Since it would use the Parallax Serial Terminal and only require me to use commands from the PST object and store characters in variables, I thought it would be easy and fun for now.

The Coding Process:

Arduino Nano on PCB

As I wrote in Chopstick Junior 1.0 (there you can see it in the robot) here comes the part with the Arduino Nano on a PCB.

Why I did this?

Well, it's just a try to use the Arduino Nano for other robots too. This gives me the chance to remove the MC and put it in another robot or just upgrade this one with a new Nano. But the most important is that I can connect all the servos I need directly to the board without any solering or using male-to-female cables.

That time of the year...

My budget this winter is ~$150-$200 USD, and I've decided to delve into robotics; now I just need to figure out what to get.

I've been asked how to cut acrylic with a hot wire cutter - I made my own and there are a few plans for how to do this on instructables etc. This was my take on the idea which I find works OK for me... - see the file attached

Botboarduino drivers

Ok guys it's been a while since I've been on I'm glad everything is picking back up.

I recently had to wipe my computer after getting a virus. Which means I lost all my drivers and code and etc. I managed to get arduino up and running but my botboarduino needs drivers to work. I'm kinda freaked out about catching another virus and I can't seem to find the correct drivers for ft232 uart. I tried one place but it keeps asking me for a password to open it. And when I point the device manager it refuses to see the zip file.

My artificial neuron approach

February 12, 2015

A single artificial neuron can represent some simple Boolean functions like OR, AND or NAND and some like XOR not, because a single artificial neuron can only learn linearly separable mappings.

Example. Perceptron for the AND function:
