I found a old digital camera with internal memory, so I was thinking of making a robot that will explore a room, and if it ran into something or gets too close to something, it will take a picture of it. Then when I think it is done I will hook the robot into a computer and withdraw the pictures from the camera and see what it thought was a threat.
ideas and suggestions?
this camera will not work,
this camera will not work, it has bad software 
Anybody want to donate a digital camera?
I would first figure out
I would first figure out what you want the "threat" to be.
With limits in processing, I would either go with shape, distance, or color.
With shape, you would need to have something to scan and figure out what size/roundness/spikyness. it has.
Color would be easy with an RGB sensor.
My thinking exactly. I was
My thinking exactly. I was going to go with distance, making it quite simple to create a distance sensor that would take a picture of whatever was infront of it or blocking it.
A few things …
There’s a bot somewhere on this site that does a very similar function. Just drives around and takes pictures of things it runs into. Haven’t seen it updated in a while, though.
Also, if you’re looking for a digital camera, they have kiddie ones or really really cheap-o ones for around 10 bucks at places like Walgreens.
Lastly, can you go into some more detail on the “threat assessment” aspect? I find that really interesting and I’m curious to hear what factors you’re going to take into account to determine something as a threat or not.
This robot will be using
This robot will be using cooperative multitasking and several states if triggered:
1. Go in x direction
2. Threat detected?
2a. NO: Go in x direction
2b.Goto 3
3.Sensors tripped?
3a. YES: Take picture, goto 4
3b NO: go in !x direction, then go in 45degree of x
4. Do the following
Sound buzzer
Turn 45degrees
Still thinking of what it will do 
I would add some sort of
I would add some sort of thermal/heat sensing ability to this as well. Last thing you want is your bot to become Bo-tartar as it heads into the broiler of an oven…
Well if you want it to show
Well if you want it to show you what it thought was a threat, maybe add an action.
Check to see if object is a threat
no- go back to main program
yes- alarm sounds and goes back to origin
might be fun to try
Uh, cuisine
Not really relevant, but tartar would be ground up raw and served with raw egg and perhaps capers. Bot-Flambeau on the other hand, is what happens when an h-bridge attempts to drive motors way to big for it.
