I think what you are doing is awesome!
So I have been testing the 8085 CPU and the 8155 peripheral chips. As of now I have not been able to get the 8155s to work, however I have tested the 8085 and it seems to be working (I checked the A/D lines and the Read, Write, IO/M, and Address latch lines with an oscilloscope, and they seem to be operating correctly).
I also read the data sheet for the 8085 again and found that a RC network was needed on the reset pin, and that a capacitor was needed on the 3 MHz crystal, so I added them, but it did not fix the problem.
When I was examining the chips, I found that the 8085 marked 8085A, and that two of the 8155s were marked 8155H-2 and the other was marked 8155HC. It turns out the H in 8155H-2s signifies that they are HMOS versions of the 8155, and the 2 means that they are faster versions of the 8155. I am now wondering if I have a compatibility problem with the 8085A interfacing to the 8155H-2s.
I still have more testing to do on the 8155s, but if I can't find the problem, I will probably post on some EE forums to see if anyone has any ideas as to what is happening.

you will want to use a servo (which just means there is close loop feedback control) so that could be a brushless motor or any other type of motor. Brushless servo motors are very common in industrial applications. if you have a geared reduction (which you will probably need) low backlash will be very important.

Just ran into this today . . . how to make a cheap custom fume hood for all your soldering and dangerous chemical needs
This looks cool. I think I need to get one of these as I've been inhaling way too much fumes lately and have been coughing like a miner.

Last week I received one of the units in the link below, after downloading the UTFT and UTOUCH
libraries I was able to get the Display to work with the arduino setup codes listed below, but after
spending days searching the net for different setup codes I still can't get the Touch function to work.
with these codes, it response to a touch but, only returns -1 myTouch.getX(), and myTouch.getY();
after doing a calibrations it returns values if 0 for both X,Y but does give a pressure value.
link to the item: http://www.sainsmart.com/sainsmart-mega2560-r3-7-7-inch-tft-lcd-screen-sd-card-slot-tft-shield-for-arduino.html
arduino setup codes:
UTFT_Buttons myButtons(&myGLCD, &myTouch);
because I get good display results and at least it responses to pressure I'm thinking
it's my setup codes.
anyone had a chance to work with this unit and get the touch working?

That is EXACTLY one of the other problems that I was having. my only recourse was to buy a hardware
programmer from China. Studio 4 did recognize the device , and appeared to "talk" to the Axon.
The only problem left, was to compile a source file, ultimately, to an ELF file. This is the point
that I am at now. (hardware device is in a 500 series, as defined in the document files)
I loaded Studio 6.2, and tried the programmer with that. Did not work.
HOWEVER, the source file DID
make an ELF file. At that point, my 500 programmer would not
work with studio 6.2, but the program requested a 600 version. I looked this up, and it was
expensive. Tried to use the 6.2 studio ELF file to be loaded from the Studio 4 platform, to the
Axon, but did not
work. (Was a long shot, just wanted the thing to work.
Trying to use programmers and files from different platforms will not work, as libraries and
protocols are different.(I found out the hard way). If you can derive a solution, Please advise.

Also, even though i install the USB driver, it doesn't recognize the device (Axon II in this case). Do you know what is the problem?

Here's a little update on the project. Finally got the hand bones joined and ready to rig!
Also, here's a link to the hand video where I demonstrate its range of motion:https://www.youtube.com/watch?v=mRTtyT2cWaI

Yes, I have had a similar problem. I can not convert to the elf file, which is needed for final
download. Even then, you may not be able to download via your USB, because you may need
a "virtual" USB software driver.(available in the tutorials). I eventually bought a separate hardware programmer, which studio 4 recognizes, but still did not have the elf file.
Getting closer to the answer, though.................

Hey guys, im working on my first robot, so i`m new to robotics, also new to programming, so, when i make my project with Project Designer, i get to the point where i need to convert the code that PD made, into .hex. I do it using AVR Studio 4. As it says in the tutorial, i go to build, then Rebuild all, but it always ends up with an error :
make: *** No rule to make target `../../../All', needed by `VR_Axon2_demo.elf'. Stop.
Build failed with 1 errors and 0 warnings...
So, i got stuck by this, and i cant really do anything. I did it several times, and i always get this error. I`m using WindowsXP, and i think that the problem is naming the files, and i don`t know where i did wrong.
Please help meee!
