bots in real life
 

To tell the truth, I only began coding bots because building a real robot appears by far too expensive for me. recently the control of my parent's solar collector likes to pump warm water to the roof, therefore I was searching for a replacement for the control unit, coming along different types of uControllers. Especially this one looked promising, at a cost of 28€ providing everything I need. So I bought it. It should arrive in the next days ... well, first testing different stuff, then maybe starting building those things I initially wanted to build and code ....

my bro tells me about caring more about the girls, but hey, who needs one if you can build a baby like this without external help ;D

oh noes, so now you have to waypoint your room? :)

Re: bots in real life
 

No - he will use RealBot method of learning paths from humans. :D

Re: bots in real life
 

that sounds crazy.. then you'll attach guns and missles and send them after your enemies :devil2:

Re: bots in real life
 

so, first testing that little board, little steps, just soldered the connections :)

anyway, gotta go to bed :sleep1:

Re: bots in real life
 

btw, about waypointing and stuff ... that little thing has 1k of RAM, 16k Flash, 512byte of eeprom and 512k external flash. so I guess complex stuff has be done maybe on a pc linked wireless to the bot itself. anyway, just fucked up the bootloader, thus I cannot upload programs via RS232 anymore, I gotta build me an ISP programming cable ... all those little things you gotta take care of ;)

Re: bots in real life
 

Isn't that thing overkill for controlling a water pump?

Hey, I was thinking. What if you tried to fix the fried component(s) on the old controller and kept this one for yourself?

Re: bots in real life
 

pump control done, also data logging onto a flash device ...

All you need is one of these to tinker with.

http://world.honda.com/ASIMO/new/image/01.jpg

The New ASIMO has made great leaps forward from its predecessor. In fact, the New ASIMO can walk along with you (holding your hand if you wish), and features advanced mobility, to the extent that ASIMO can now move carts and other objects around at will. And, with a newly developed total control system that controls all of ASIMO's functions, ASIMO can autonomously act as a receptionist, or even deliver drinks on a tray. The New ASIMO is also more agile than before, being able to run at 6km/h, and even turn whilst running.

I can't wait for the blow up doll model :)

Re: bots in real life
 

guess that won't be cheap ...


but with a nice SDK it's worth a thought ;)


about if this stuff is overkill for a single pump : well, you could do it using operation amplifiers, but then you won't be able to log data, which is just a nice feature, and calibration wouldn't be easy. Those Atmel AVR controller basically need only one external resistor to pull up the reset pin, and then you just need to connect the inputs and outputs, assuming you already programmed that little thing. that's possible via a cable attached to 4 pins of the cpu and your parallel port. so it's quite easy. and that controller already contains normally 8 AD converter, quite some output/input ports depending on the package the controller comes in, some internal flash, eeprom and ram, different timers, serial bus, rs232 stuff ( though without level converter ), ...

below the minimal setup with a lcd display and serial connection

just checking on sd/mmc card information, looks quite promising, having a lot of cheap storage space for different types of measurements :)

Re: bots in real life
 

currently another rather not bot related topic

state of the longterm-ecg- prototype : http://johannes.lampel.net/pics/IMG_0825.jpg

Re: bots in real life
 

Well Well Well
so you want to build a real mechanical bot!:nuke:
Actually that's every freaky bot programmer's dream including me! just Wow imagine , what you could do ..... like getting an army:gunsmilie: of those little machine-heads and conquer the World ...MUhahahahahaha:devil2:
but seriously : I think that anybody who plans such an ambitious scheme should first of all worry about HOW you gonna physically construct the mechanical body of this robot ....
however the programming of the robot would be the most easiest part , at least from my angle of view.

anyways , they say that imagination rules the world:)

Re: bots in real life
 

Did you remember to put 0.1uF capacitors near the digital ICs from their power to their ground?

Re: bots in real life
 

yep, sometimes more ... and sometimes even an inductivity for the really stable parts :) ... the black little boxes on the left there do not need any caps, since it's only 2 optocouplers :)

Re: bots in real life
 

Oh, I thought they were some kind of logic device. Well, I guess digital IC still applies then, and some analog ones, also.

If you use two power supplies, you can reduce the need for those.

Re: bots in real life
 

AHHHH excuse me if I'm standing stupid 0_o in this thread , but what is it exactly that you're constructing that takes all this Hi-tech ?
a water pump? , a Robot? or a water pumping Robot?............Or is it a Water pump that playes counter strike while pumping Water??

Re: bots in real life
 

yeah, that might be an application ;)

currently i'm just getting to know that stuff better, currently i'm building an ECG, which already produces nice results, though just one channel until now

Re: bots in real life
 

once again a picture ... just soldering the 3channel ecg :)

Re: bots in real life
 

Did you know you can make PC boards with photo paper and a laser printer? Well, I mean you will still need etchant and the copper clad. You can make the etchant work better with a fish tank heater. You don't want to use something that gets really hot, though. You can also you an air pump from a fishtank to accelerate it.

Re: bots in real life
 

For Gordan Freeman's sake ! Can someone tell me what in the freaking Hell you are wiring together , dudes!

Re: bots in real life
 

Well, it was a pump controller, but this one might be for something else.

Re: bots in real life
 

yep, I know, but I thought this project is still small enough to be soldered manually. i'm thinking about some improvements for the setup already, I guess then I'll do it that way. or go to some shop to make me a double layer board

btw: the status from yesterday : mmc card is running, only the actual amplifiers are left to test, all digital stuff is working fine :)

Re: bots in real life
 

BTW, there are standards for how much current your sensor can draw. I don't know it exactly, but MOSFET buffers might be a good idea.

Re: bots in real life
 

what sensors you are referring to ?

Re: bots in real life
 

It's an EKG machine, right? I am talking about the probes that attach to your skin.
