You have either too much time or too much money....
Perhaps both?? Robots see Pixel grids in shades of grey (or colours) each pixel is graded.. A "memory" of a pixel pattern can be learned and tracked.. |

I'm guessing infrared detection with a correction loop for maximum signal strength, fire when signal is maxed for 1 second or longer.
Of course there is radar. Maybe you could use 2 motion sensors paired up and seperated by a foot or 2 to give it stereo "vision" so they could figure range to target for elevation. I keep getting this funny as hell image in my mind of these robots chasing you around the living room blasting paintballs on all your funiture and walls. [:)] |

can't be done with existing technology.
you need fire control, ranging, stratagy, self perservation and mobility. try to key on heat. you don't need to range because it's paint ball and and your max range should be 25 yds. so you got this black box with a simple IR eye that will trip a relay and fire when it detects heat so it will fire on lamps the stove etc. complex recognition software is just being developed and is major expensive. |

Most of it is possible, and shouldn't be too expensive.
The strategy wouldn't be impossible to code. That would be the fun part. Robot motion, no problem. Using camera, infra-red, or radar (maybe stereo), I could get a continuously updated pixel-map or 3D-extrapolation. What I don't understand is the algorithms that would analyze the raw data and separate the target from the background. I'm not going to spend money on expensive software, but if I can find complex-recognition algorithms, I can write software to implement them. |

Terminating capabilities will be limited by the 31-inch max range on those sensors, but it's a good start. Should the robots disobey their creator, I recommend a defense-system based on magnets. |

Just to track a person, Infra-red I think would be the easiest. Simple units from a home security system might work. Use a couple with narrow search width with an alogrithm of if outside unit has a signature the robot rotates to get the signature on the center unit (over barrel).
As for strategy, use the Quake engine. I think it is open source now. There is basic AI in there. Hell, I heard some time ago that the military was thinking of using the game Quake as an infintry simulator. Never heard much about it. Go over to [url]www.slashdot.org[/url] and post the question. Lots of geeks there with some great knowledge on weird shit. |

Get a clue, all of you nay-sayers.
Robots: 1) Can communicate with each other quickly and synchronize their motion, allowing for tricky strategies. 2) Don't mind making suicide-attacks, when it's for the good of the whole network. 3) Have small profiles, so are harder to hit than friends. All will be welcome to engage against the robots. No one will be forced to (however, if I am incarcerated, then I might not be capable of preventing them from running amok). |

... Try a looking into shape recognition. There are programs and routines like Borland Delphi 3 that recognize the shapes you create with a variety of tools. Just replace the shape with a rasterized image, which is easily created with an off-the-self digital video camera. You then slave your 3-axis servo controllers (provided you have accounted for its logic) from the your algorithms developed for your particular parameters.
You'll need a fast processor to react as fast and sometimes faster than you with paintball guns but I've made it work. ... I'll sell my models & schematics for a fair price if you're not too cheap. |

A "memory" of a pixel pattern can be learned and tracked.. Until the target turns, squats, stands-up straight, moves their arms, moves their gun, etc.. Look at how slow and unreliable OCR systems are. They're pattern matching a simple black on white unmoving "target," and aren't 100%. Don't forget analog. It isn't that hard to find movement or sharp edges. You can do that with a few dollars worth of parts that don't weigh nearly as much as a computer. I guess since it's a just game, you could have the system look for a certain hue of shirt or target that you're wearing to make it much easier on your system to aim. I built a system about 8 years ago that straightened and checked for folds on shower curtains before they were hemmed. My solution was about $40 plus the camera. The solution the plant came-up with internally used a $20,000 DEC Alpha, $5,000 capture card, and a much more expensive, higher-quality camera. If you can find an old TV or oscilloscope repairman, they can open an entire new world of highspeed video processing that the digital world can't touch without expensive hardware and custom software. Ahh, good old analog.z |

Analog sounds good. Where did you learn the how to do the shower-curtain vision? Is this covered in textbooks? |

definitely not on railroad-type tracks. I was hoping to take them out to the desert.
They would move using tank-type tracks. Individual robots would be pretty non-intimidating -- just large enough to swing a paintball gun around. Unlike with Robocop, their strength would be in their number. They'd pull stuff like lining up to reduce profile (like a SWAT entry); and they could surround their targets and fire inward, and their robot precision would reduce the chance of friendly-fire hits. They'd all be communicating in a point-to-point network, so there'd be no central robot to get knocked out. |

Even if this guy is full of it. I personally think this is a great idea and sounds like fun.
Hell we play shoot'm video games, why not with real robots! There are robots out there that work as a "unit" and can work with each other to accomplish simple tasks. I've seen the ones that re-arrange the funature for you, gather objects to be placed in a specified location. Alot of the code for this is open source. Sensor technology has come a long way. I remember the vision system for driving a car took most of a moving van and max speed was less than 1 foot per hour. Now it can be done in the trunk of an average car with average speed of 65 MPH. And yes Virgina, they do have cars that drive themselves just on vision alone, and manuver around obsticles, take off ramps. It just isn't cost effective and the acceptance of having a computer drive isn't there. |
