RoboGames

This weekend I went to the annual RoboGames in Santa Clara and I saw hundreds of robots and general geek projects ranging from a electric guitar controlled by an Ipad to a 220 pound r/c controlled robot with a 50 pound hydraulic ax on it.The RoboGames is an annual 3-day robotics competition and exposition for young and old.  There were robo-wars ranging from tiny 250 gram robots to the 220 pound robot I just mentioned. But there were not just robo-wars, there were also displays and challenges that some of the younger teams equipped with a LEGO Mindstorm robot could do. I saw some small robots that inspired me to make one of my own a wedge robot.Here are some pictures that chronicled the days events:

These next photos are ones I took myself and are a little bit lower resolution.

Are You Stickin' Me?

I have an old analog joystick that I took apart and I found it had three potentiometers that worked nicely with my Arduino.I wrote some code and I had it read the values of all three potentiometers and display them in the serial monitor window.
Here is the code:


int potx = A0;

int poty = A1;
int pott = A2;
int potxv = 0;
int potyv = 0;
int pottv = 0;
void setup(){
Serial.begin(9600);
}
void loop(){
  potxv = analogRead(potx);
  potyv = analogRead(poty);
  pottv = analogRead(pott);
  Serial.print("X Value:");
  Serial.print(potxv , DEC);
  Serial.print("Y Value:");
  Serial.print(potyv , DEC);
  Serial.print("T Value:");
  Serial.print(pottv , DEC);
  delay(500);
}
* NOTE: this code is made to work in the Arduino IDE although it may work in others.

I am thinking about posting this as a project on the MAKE magazine website.
That's all for now.

Ideas

What makes a robot a robot? Is it the ability to be autonomous? Is it the ability to move around or communicate with something? If it had to be autonomous wouldn't we be classified as robots then too?
So, I'm wondering what makes a robot a robot.Is it that it is electronic?What makes it a robot?

Is It RoboRealm Or Is It A Human Eye

Any of you heard of RoboRealm? RoboRealm is a robot vision program that can do anything from photo shopping the video from a camera to move the robot to avoid obstacles using only a camera and the software.
I tried the 30-day trial for free and am partway through it at the time of writing because it carries a hefty price of around $50. This software can control most of the Lynxmotion, Lego Mindstorms, and the some of the robots made by Irobot such as in the Irobot Create or the Rumba.It can also apply filters and read characters from what the camera is seeing among other wonderful things.
