My robot is coming along well (the research one for the university.) I will finish the physical/electronic design this month, then I will start the programming. Not too much to report as far as progress because most of it has been done on the schematic. I did pick up a nice Sony VAIO laptop that is only 4 lbs - NICE! Check out the website that no longer serves as a home for the company I was developing, but rather a portal for robot activity.

If you stopped by LivingCreatures before, this is just to let you know that we have a new chat available to our members.

My companies website, www.LivingCreatures.com , has gone through a complete redesign. Not only does it serve as an information center for our upcoming products, but it is also a complete web portal where you can post to different forums and participate in the community base. Please check it out.

The humanoid robot is coming along well. The structure is carbon fiber, with a little aluminum and brass throughout. I have modified all of the servos for a 4-wire interface and have mounted them. Some are permanently fixed with epoxy, as this was the best way due to the size constraints.

In other news, my company website is up, although it is being redesigned. The tough thing with a start-up is getting everything that needs to be done - done. You can check it out and send me an email on what you think. I should have some photos of the humanoid project available soon.

Wow, it has been a while! My scaled down humanoid project is now funded by the University. Although not designed to perform its original function, it is nice to finally have someone else buying my parts for me :-) I should have a copy of pro/engineer arriving at my door in the next week, which I will use to model the parts. I picked the Axiom PB555 processor to run the robot- this is a kick butt processor, but it is not for the lightweight. I should have more regular updates happening since this project is going to rule my life for the next year.

Just letting everyone know that I am still around. The quarter is almost over and that means more time to be working on robots. I have an idea for a micro actuator based on muscle wire that would be fully proportional and act like a servo. What would be the advantage of this? A fully functional robotic human torso measured in tens of grams :-) The interesting part will be trying to make these little things. There is a company trying to sell "nanomuscles", but they want $21 each in volume, which is way more expensive than the $1 a motor would cost. The design is good and I started thinking about it when I realized that the current design for my robot is way too expensive for it to be repeatable and something everyone could enjoy making. If I was able to design the robot with a couple of atmel controllers and leave out the rabbit 2000 and use these new muscles to power it rather than the servos that I have, it would be smaller, lighter and most importantly- cheaper. Just a thought to let everyone know that I am still around :-)

Well, I am sorry to say that there is not much to report. I have had a few personal set-backs, so any hobby has been the least of my worries. Keeping up with the influx of mid- quarter approaching is keeping my spare time busy. It is likely at this point that there will be no significant progress on anything until Dec. If something does come up I will certainly put it on here.

THe latest update.... I am still pluging away at the project even if it is a bit slow. School is occupying most of my non-work time (duh). I have both arms made and just need to update the linkages in the elbows. That is about the extent of the project at the moment. I am having fun with physics and I found out I have possibly the worst instructor for calculus 2. I just put in my application for the Foresite Institute's Nanotechnology conference in Santa Clara. It is November 8-11, so if you are interested in Nanotech that is the place to be! I opted out of the lunch because I figure at an average of 50 dollars a day I can get a good lunch elsewhere. Rooms are a group rate of 120 per night, but I did notice on the web they were selling at 89 if you have AAA. I am looking forward to this event in the hopes to make contacts in the industry, or coming industry as it may be. Not doing much research in the field until next summer (when I hope to do some for NASA's Dryden research facility) so I doubt I will have much insight for others to be impressed by, but I have a few ideas :-) That is about it.... if you had thought of going to this conference drop me a email and we can meet there. That is about it......

I am still working on my project. Now it feels a little wierd to be working on. With all the talks of war and being a veteran myself, I wish I could do something more meaningful for those that will fight this campaign. But, I guess for the country I should continue my life as normal, which is what they asked of us. So, I am still plugging away, I have a slight problem with the linkages for the elbow joint that I will try to work out over the next few days. Other than that, no homework this weekend :-) but I do have to work :-( Hopefully, I will have a more up-beat diary entry soon....

Alright, school is in it's second day and hasn't gotten too busy yet. My physics instructor is stuck in Paris, which everyone seems to think is the best thing in the world, but personnaly I would rather be stuck in Germany or some other European country (Paris is a dirty town in my opinion). Work continues on the humaniod robot. On the issue of scale, I realize that I may have not given this before, the robot will be from the waist up an approximate 1/10 scale of me. Yep, I took my own measurements, scaled them down and converted them to metric. The latest is that I have machined (1) lower arm and it is one of the easiest pieces to date. All I really had to do was cut to length, remove 2cm of one side of the angle (for mounting) and bore a hole for the brass tube that fits into the ball berring. It is currently drying (JB Weld again) along with the other elbow. That leaves (1) more lower arm and both arms will be complete (less any hands I may decide to add). Then I will place the ball berrings for the upper torso and mount the torso servos. The next step is to attach the arms to the torso with more brass tube and then I will have a working chest/arm assemble. Incidentally, there are a few more photos on the TRCY Robot club on yahoo in the photo section under "Nathan's Projects". I still do not have a more convenient place to put these photos, but I will figure one out soon. I know that joining a yahoo club just to check out some pics would suck. Actually, the TRCY group is really active, with chats every Sunday, Tuesday and Wednesday. Sunday is hit and miss sometimes, but Tuesday is designed for beginners and Wednesday for general chat. I will have pictures of the completed arm up on the TRCY website over the next few days....
