Hi guy's and girls, I just signed up to this forum - just a quick message to say g'day  Ive been interested in robotics for a while. Im a software engineer by trade, but like to play with real world interfaces - pic microcontrollers etc. I usually never finish my projects though, cos i get too excited about the next project half way through before the first ones done! I plan on making a painting robot/machine - that will make oil paintings (portraits etc.) Has anyone done anything similar in the past? Any hints and tips? Cheers, Michael |

G'day, seems like a few of us here have programming backgrounds and want to add the real world to our list of interfaces  Do you program in C mostly or something else? What sort of painting robot? something like the Scribbler (carpet rover with pen attached) or like an arm that draws on a canvas? Both are cool. oh yeah and Welcome! |

Hi again. Thanks for the welcomes At the moment I mainly do VB6, and will be moving on to C# soon. Most of my commercial experience has been in COBOL though. In my spare time I like to do Assembly programming for PIC's - as crazy as it sounds I actually enjoy whipping up Assembly code Have only been doing it for a couple of months though, i'm fine with writing code but not so much with electronics (have killed many a PIC so far). To answer your question Dingo, my goal is to build a robot/machine that will produce an oil painting on canvas thats indistinguishable from a 'human-painted' painting. Very difficult yes, but I think it'd be an interesting project (and possibly a source of income in the end?) Thanks for the link Bones That robot looks pretty sweet! Ive seen a few art bots on the net that are pretty awesome Its a good inspiration! I live in Brisbane btw. That group project sounds cool. How's it coming along? I havnt had a chance to read many of the posts on this site yet, but i'm getting around to it What sort of things are you's designing/working on at the moment? Cheers, Michael |

Sorry Bones, seems like Brisbane is the hub You'll just have to come on over Ok, so we now have 3 confirmed Brisbane people in the community (Michaelg, Dan and me) and you know what they say, three is a crowd so I reckon we should get together. I think Dan is busy at the moment but hopefully he'll re-surface and show off his very nice bot. I can bring along my "blind  " carpet rover  I'm just North of the city and Dan is just South so I'm not sure where is a convenient location. Anyway if you are in need or finding supplies in Australia or that post to Australia easily don't forget to check out the links page www.users.on.net/%7Esymes/links_tree/links.htmBTW how big are you thinking of making your "Rembrant"? |

I live just out of the city - in Toowong area. Unfortunetly I dont have any robots in my arsenal just yet - just a couple of half-finished contraptions (a motorcycle computer, POV device, but no robots yet). Thanks for the link Dingo - that site looks awesome, it'll definetly come in handy. So far I've mainly been getting my supplies from futurlec - and Dick Smith/Jaycar when I cant be bothered waiting for shipping. To answer your question, I havnt really decided on how big to make it, but it will be scalable. I plan on having a small module that will control the brush to create a brush stroke in a small area (maybe 20cm by 20cm). This will have 4 stepping motors - one to move brush up/down, one to rotate brush, and the other two to move it along X/Y axis. This assembly will then be moved along X/Y axis to paint a brush stroke anywhere on the canvas. Right now i'm writing the assembly code for the PIC to control these 4 stepping motors from parameters that are passed from the PC - these will be variables for a parabolic function for each motor Tell me about your blind vacume cleaner bot Dingo - does it work well? Thats also something i've wanted to do, build bots to do my housework |

That is a great find. I've also had great success in old laser printers (and I assume other types would be equally as good). I've found it is great to pull a stepper motor and a whole bunch of cogs that already work together and then just "re-purpose" them. Gots to love da eBay BTW those cheap servos you see on eBay, the green 17 gram ones are pretty good and well built and that seller has an even cheaper non eBay store here: www.bidproduct.com/part/Product_list_SERVOS_1.html |
