Mechanics and Construction / Fluidic Based Actuators
« Last post by joeedh on Yesterday at 04:58:25 PM »
Hi all.  I'm a computer graphics engineer, and for years I've dreamed of building a small, compact robot with dozens (at least 24) of actuators (mostly for research).  Recently I've been trying fluidics out (with compressed air), and I was wondering if anyone else has ever done that.

The basic idea I had is to attach a mini solenoid valve (like from blood pressure monitors) to a fluidic valve.  The solenoid valve takes an air stream of, safe, 4-5 PSI, and uses the fluidic valve to amplify it to 20-30.  That then drives a pneumatic actuator.  I have a 3d printer, and I've managed to get a fluidic valve that seems to work (it works the way I want it too. . .but, not the way my books on fluidics say it should, heh), and I've ordered a little solenoid valve.

The fluidic valve, including the solenoid, works out to about 25mm x 55mm x 20mm tall, so about 1'' by 2'' by 1''.  I haven't decided what to do about the actuator yet (air muscles?  Disney's pneumatic rack and pinion setup? a pneumatic stepper motor?), but I'm planning to start with simple air muscles (because they are easy).

Anyway, thanks for any replies.
 :) Hello!  :)

     There are vendors advertising on the right hand side of your web - screen that may be of help.
I have looked at Lego - mindstorms at Toys are us; Mechanoid Madness posts, where you have a
cute robot to assemble. If you visit Youtube for Mechanoid Madness, you can find a slew of suggestions!
Good Luck, and have fun!!   ;) :) :D ;D
Mechanics and Construction / Is there any standard mechanical parts to make robots?
« Last post by rezaee on August 20, 2016, 03:46:41 AM »
I want to build some robot packages for kids, but I don't know if there is any standard parts to make robots?

I mean some things like this photos:

What keyword should I search to find factories that make this?

Thank you !

Would someone suggest alternate options for Pioneer 3-DX robots? Also plz provide any relevant details for me to compare...Thanks

 :) Hello!
I am a strong supporter of the Axon board. I love the design of the pinouts and general attributes. I get frustrated
with it because I can not get access to program it.  If we could use yours in place of the processor, or have a dual core
STM32 for the brains and the Axon for the physical interface, that would work. Ideas increase immensely if you have
an open, intuitive IDE for programming; People will program it.  ;) :) :D ;D
Electronics / Long distance Metal Detector schematic

Hello ,
can anyone help me with a circuit for a metal detector for long distance range (near 30 cm )

Really interesting. I've never seen a multi-core MCU  :D. For now, I do not know what shape project will have in the future . We'll see if it will be useful! I do not know the language FORTH so I can not say if he could compete . It seems to me that the raspberry is designed for some other purposes than boards which use stm32. Also I think it's a great idea to put this processor into some version of Axon board . ;)
Not really robotics related but I had been researching security cams to use on an RV lately, so I figured I should share what I've found...

If you have wifi near your vehicle I'd recommend something like this:

Otherwise this should last 7 days on a charge:

Hunting cameras should also be good...just make sure it doesn't use flash, or they'll smash your window in to steal the camera:
Software / how to install AVR Studio 4 on Windows 10
« Last post by Admin on August 16, 2016, 02:20:43 PM »
It took me half a day to figure out how to get AVR Studio to compile on Windows 10. I kept getting errors looking for rm.exe and what-not.

Do these steps in this exact order:

1) Install WinAVR
2) Install AVR Studio 4.19 (the last version in the v4 series)
3) Place the attached mysys-1.0.dll into this directory:
4) Load up AVR Studio, it should compile fine

 ;D Cool!
       I have found, programming a processor, and exploring the full dynamics of
it are addictive. it is easy to get lost and delve into the machine code, to see what is really
going on. I had this experience with Parallax's Propeller. Open source, great to spring board
into. I could not proceed without the forum. The forum, and thus, people to use the propeller
for different uses, have grown the product to fantastic heights. That being said, the same could
happen for your process; having a vision for your destiny of your path is critical. Creating excitement
about programming, and the internal workings only come with applications that are useful, or
curious, for the user. Questions like, can this processor be programmed to function like a
dual core? If I do, can it rival the programming power of the Raspberry Pi
? (Using FORTH)
What commercial or home uses do you have in mind? Radios, drones, washing machines,
personal robots, telephones, and/or small computer could be a target.
Could one be put on an Axon board, to replace that processor? Just a thought.  ;) :) :D ;D
