Hey y'all! I still have a few mechanical problems to fix on T.R.A.P., and since I got my parts today I will start working on them tomorrow. I am going to clean up my weights for the base, paint em, and then I'll mount them onto T.R.A.P. I also have to tighten up the shoulder of the arm. After I do this stuff all the mechanical problems should be fixed. I may also go for a higher power AC adapter to power the servos and give them more power. I've already tried a few programs out. And when I finish fixing all the mechnical problems I am going to try a few more, and then I am going to start on the PS2 controller and getting it to work. Over and Out

Well, I got my OOPic-C working after all. I can't believe it took me so long to figure out what was wrong but I had to figure out which pin on the Atom Bot Board correspondid with the pin and I/O line on the OOPic-C. I tried a servo program out and it worked. I am glad that the microcontroller is still good because now I get to program in C. I guess I will either sale my Basic Atom or save it for another project. Well, I'm going to start on programing T.R.A.P. now and hopefully find some code for the PS2 controller or come up with some myself.

Well, things are taking a little bit of time on T.R.A.P. I got the microcontroller hooked up and it was blinking its oboard LEDs that let you know it is working(a diagnostic.) Everything went wrong when I tried to program my OOPic-C though. I was testing it out with a LED which I was trying to get it to blink. I had the LED hooked to the right pin inline with a 1k resistor and to ground, but the thing would just not blink, and I know my code was good too. I also tried a simple program that makes a servo motor spin all the way around, but to no avail, that didn't work either. I do not know what is wrong with my OOPic-C. I hope that I didn't fry it, but I am getting a reading from its EEPROM, I don't know. I guess I will have to look at it later. As far as I have read you put in the code, compile it, and then it should start executing, but mine is not doing a thing. For now though I have just ordered a Basic Atom. With the Basic Atom I will not be able to program in C, but at least I should be able to move on fairly quickly. I am also working on a few mechanical things on the arm, like adding the weights to weigh the base down, but also I have noticed that the servo horn that the actual arm is connected to is bending a great deal, so I am going to have to do something to ease the stress, asize that everything should go smoothly after I get my new micro put on and programed.

Well, I finished T.R.A.P.'s base and have mounted the arm onto it. All I have left to do now is mount and hook up the electronics. I also need to weigh down the base so that the arm doesn't tip over when it's fully extended. I hope to have T.R.A.P. going soon. Here is a link so you can see a picture of it: http://madcybo rgscientist.tripod.com/

Hi, I finished putting my robotic arm together today, actually just the arm itself and I still have to build the base and mount the electronics and then start programing my OOPic-C microcontroller. Yes, I have decided and bought an OOPic-C microcontroller for this robot and I am going to program it in C. I am calling this robotic arm T.R.A.P. which stands for "Testbed Robotic Arm Platform." I am going to build the base from dark-blue sintra. I don't know how I am going to weigh it down so the arm doesn't tip over but I got to find a method of doing this. The board that I am using is a Mini Atom Bot Board. First I am just going to do some simple motor control programs and then I will advance to other stuff. Also I am going to control it with a PS2 controller. I also have a Sharp GP2D12 IR Sensor that I am going to use as a sensor for the arm to know when an object is present. After that I hope to buy a CMU Vision System and experiment with it. I hope to get somewhere with this project very soon. I'll hollar at ya later.

Hail Dr. Who! Long live the show!!! I love it a whole lot and will always watch it. I love British stuff anyway but I really love the show because of the doctor and the robots and other tech. I am one American who is sold on the show.

I love Doctor Who! Marev, are they playing the new season there already? Just curious. I hate they got rid of the old doctor though, he was cool and fun. I can't wait for the new season to start anyway, but the new guy doesn't seem as good as the old one.

I have added some pictures of some of the robots to flickr.com. Here is the address:http://flickr.com/photos/madcyborgscientist/ I will probably add more soon.

I am not doing any robot work at the present moment but sometimes this week I am going to start on my projects again. First I am going to build the Turbot named Flip-Flop or Triad, I haven't decided yet. The Turbot is going to use a PT Solar Engine that is operated on a 1381C Trigger. The body I have already made which is cut from a peice of dark blue sintra that I bought from solarbotics.com. I can't wait to finish the bot and it should turn out nice. Next inline after that is a few more projects that I have planned. One being a Pummer and the other being a Photovore, maybe. I am going to start on my arm soon and I keep saying it but I have to keep telling myself to get done with these other robots before I start. I really want the thing to be cost affective though. I guess I will have fun with my BEAM bots intill I get to the point and made final decisions for the arm. Tonight I have to go help set- up sound equipment for my church since I will be the sound guy. Well, I'll keep you posted as new developements take place. Bye for now, my fellow roboticists.

I am doing robotics again, finally! I just got one BEAM robot done which is a solar roller named Blau for blue of course in German. Next I am going to build a Turbot and I am probably going to name it Flip-Flop. I haven't decided what circuit I am going to use but I thought about using some kind of solar engine with a light sensor so the Turbot would move towards light but also have caotic movement instead of just flipping forward. In the mean time I am still looking at ideas for my robotic arm. I haven't fully decided on what microcontroller to use. I want something that is somewhat powerful and has a built-in servo controller. Also, I want something that is like a developement board so I can try circuit out and other stuff. The mini Atom board that I looked at has this neat PS2 controller port and shows you how to program it to control a robot with a PS2 controller and the thing has a built in controller board for up to 16 servos. It is a purdy powerful controller too, the Basic Atom. I do not know all the spects on all the controllers but it is more powerful than the Basic Stamp. The only think about the mini board is it doesn't have a power jack or a developement area, it's all pins and no I/O buses with connecters. I could buy the board for the Basic Atom that is the developement board but then I wouldn't have the servo controller built in or the PS2 port. Maybe I can find a way to connect it to the developement board. Well, recently I built a Jacob's Ladder. I have been wanting a Jacob's Ladder for some time now. I bought me a 11000Kv neon sign power supply off of ebay. I paid $20 something counting the power supply and the shipping cost. It puts out a decent purple arc that is about 2 inches long. I just used a piece of wood my dad cut me off and made the V part out of some 10-guage copper wire. The V shape part is about a foot long minus the part below it that supports it in the air. Well, I hope to have some more bots going soon. Maybe I will come up with my ideas soon for the arm and the others and be ordering me some parts soon. The arm is really going to deplete my funds though. Its going to be somewhere in the neighborhood of $400 or $500 when I am done with it. Who knows, it may end up being $600 or more, but I doubt it. Well, I'll hollar at ya later.
