Let's Make Robots!

Free Range Robots (IR Beacon) **UPDATED**

**Update 4.14.09***

OK, when you watch the video... 

First of all, it is like, 5 minutes -sorry. There is a point though promise, and that point starts at about 3:40 or so. Now, I can't stress enough, the code is wicked chunky as it was written in about 10 min. It is all "bang-bang" and not proportional at all. The final code should be about 10x faster, much more accurate with a lot less trial and error. For now, this is just proof of concept and indeed it has been proven.

Well, here we go... Please watch the video, it explains a lot.  ******Already an Update.... sigh****** I forgot to add some baby … Read more
After many, many tests and trial runs, I have started cleaning up Walter's electronics and mechanics to a state that is a little bit closer to what it will be when … Read more

*****Update 2.16.10*****

Got some data to start thinking about, guys. My thoughts of getting nice, even packs of 4 or 5 is a little out the window. To be honest, I tried to forget that I could see where the robot was facing and tried to make a decision where to go based on just the readings. I couldn't . Please note that I was seeing the readings on a LCD so left was above right not in a straight line. --Now that I think of it, I have no idea why I didn't line them up as it is a 16x2 display. Huh.

All readings were taken L to R

Explain PWM to me, please.

I just need a good breakdown. The eventual goal is to obtain higher (or much higher) torque from my motors but at lower speeds. I am to beleive that PWM makes slower motors but also weak motors. I need strong, slow motors.

Little help with Processing code

So I got my new, nifty bluetooth module which should be a simple data-pipe i.e. data in/same data out. It came default in slave mode but alas, at 115,200 baud! I need this guy down to 9600. I am using a simple bluetooth dongle on my PC and the bluetooth module is good-to-go on the robot. I need to simply send it SU,96 during the first few moments during it's start-up. I have some simple processing code, but I am a little confused as to ASCII and hex etc.

Frits F*cked up!

Did anyone else notice this? Start here... Anyone?

Frits, if there is one thing that pic chips don't like, it is static! You know those silly wrist straps? So why, why in the world, would you take pictures of all your parts for the start here bot on top of styrofoam?!?!?!?

I personally can not think of a more static-friendly item then styrofoam. Why are you leading our LMR kids on the wrong path?

SHAME! SHAME!

Here comes science (kids)

A lot of you already know this but I thought I should give those of you who grew up in the 80's or have kids. They Might Be Giants is doing kid's albums about science now and the music kicks the most ass. The album is called "here comes science" and is awsome all the way through. My kids are now officially addicted to the elements song. Here it is:
