Let's Make Robots!

Navigation with (2) sonars Update 2 (with data)

*****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:

Birthday Tattoo!!

Well folks,

I just had the 33rd aniversary of my birth and as a gift, my wife gave me 3 more seasons of MacGyver for the DVD collection but more importantly, TATTOOS!!! Yup, a big phat gift cert.!!!! Now, why would I post this news on a geek website like this one? Well, I am going to finally get my wings. Wings of wax on my upper back to remind me of the past times I flew too close to the sun and not to again. Now I needed a roundish symbol to go in the middle and pondered what to do for a while now... I have decided (here comes the geek part)...

Omega.

28x2 Board --Your Wish List

Well, with all this Walter work going on, I find myself sorta longing for a small, fun tabletop robot --just to play with. I was looking at the standard picaxe 28x board and again, I remember how much it really sucks. No EEPROM space, ADC's have the data pin in the center, no HPWM output to the motor driver etc. etc. I know I have asked this in the past, but my PCB designing skills have gotten a lot better sense then. So, I ask again...

What pisses you off about the current 28x picaxe board and what would you want if you could have anything?

Note:

Embed Audio Signals?

So I got this nifty iPod plugged into Walter and I can easily control it with serial commands. If I were to want to sync say, movements of the head to the audio being played, I now can only do it manually... I.e. I would actually use a stopwatch and time when I would want each move to start/ continue and add the needed pauses to the code.

With the help of ezekiel181, I have finished my new on-board chargers. I just have to say this is simply the best, most adaptable charger circuit I have ever … Read more

A new sexy mobile phone...

Kari and I have been with Verizon for almost 10 years now and during that time, every 2 years, we get a new, free, nifty phone when we re-up our contract. Now, each and every time I am truly amazed how much cooler my new phone is and how much my old one sucked. Once again, this has happened. I just got a new Envy touch and well... MAN! I mean, really --holy crap!

 What you will find below is FROM A FRIGGIN' CELL PHONE!! (It has a macro function!)

Can you believe the quality?!?!
