Re: pic: 358 has four eyes!
I'm scared....one of these days you will need to explain to me exactly what your doing with these
|
Re: pic: 358 has four eyes!
why is one mounted on what appears to be a joystick?
|
Re: pic: 358 has four eyes!
Prototype gimbal.
Now we're waiting for Kevin to help us interface four cameras with only two serial ports.....any ideas? |
Re: pic: 358 has four eyes!
Why in the world do you need 4?
|
Re: pic: 358 has four eyes!
How can you justify the cost of 4 cameras and the additional electronics rule?

Re: pic: 358 has four eyes!
Do I spot a joystick base being used for the pan and tilt? How did you manage to do that?

Re: pic: 358 has four eyes!
Again, I ask (as others have) why the need for four cameras?
If you're having that much trouble centering in on a goal, I think you might need to adjust the focus...dunno.... If its for something else, such as the proposed "tracking balls" theories teams have been putting forth, I still think you could accomplish that with less.... |

Re: pic: 358 has four eyes!
You're gonna have a very hard time tracking the other robots, because they don't have illuminated targets. You'll be trying to track them like last year's vision tetras.
Secondly, how are you actually using the joystick to control the camera? Are you attempting to move the turret and as the change in acceleration moves the camera on the joystick and reading the X and Y values on the joystick? The measurement you get is acceleration and if you want to position you gotta integrate that twice and introduce a lot of error in the progress. Having a potentiometer to measure absolute position is the best way to do it. |

It's just a hunch, but Im going to go out on a limb and guess that human eyes will be much more effective at tracking robots than robots will :rolleyes: |

Re: pic: 358 has four eyes!
The joystick -> camera mount is extraordinarly effective. We used it last year to great success.
I suppose you could mount an EDUBot controller and have it run two CMUCams and then pass the values back through analog in's on the big RC... Still, 4 cameras seems a tad overkill. |
Re: pic: 358 has four eyes!
Duh, you guys are idiots. The obvious reason for having multiple cameras is for Matt's proposed method of vision multiplexing by algorithmic implementations of backwards-compatible and proprietary standards. This method is extremely nimble, with its low risk and high yield. The cameras must work in such a way that they resemble a cluster team of multi-scalable processes. From my statistical analysis, I may ascertain that the 358 robot will cause a paradigm shift in the area of FIRST autonomy.
Duh. |
Re: pic: 358 has four eyes!
Uh oh. Looks like its mounted on a vison tetra panel. That means that it'll distract our cannons... Oh wait, it's a vision tetra panel. It's not like we can see those anyways...
Perhaps it's for triangulation of their location by calculating the angles to the target? |
Re: pic: 358 has four eyes!
Wow, you have 4?! We don't even have one yet!!
|
Re: pic: 358 has four eyes!
Obviously, the four cameras will all return their own view on the subject of the illuminated target, where, in the brain, the information is fed into a highly complex social algorithm that allows all four streams to fight simultaneously. So, by the end of the match, hopefully, one will have established dominance of the others, just in time for the buzzer. Sounds great!
|
Re: pic: 358 has four eyes!
I would think you are going to need some sort of co-processor.. there's no way you can have the RC monitoring 4 cameras and still doing other stuff. Co-processor for the camera is the way to go.
|
Re: pic: 358 has four eyes!
We're going to keep color profiles of the primary colors of robots at the events and preselect them to track opposing alliance robots, it's also good for tracking multiple people and gunning them down with Poof balls.
We're working on pattern recognition for black and white stripes. |
Re: pic: 358 has four eyes!
if we're ever in the same pit, please stop by and explain to me how you managed to use all of that data in 10 seconds

Re: pic: 358 has four eyes!
And it seems like the 4 cameras might just be an extremely inefficient method of attaining hardware fault protection. In this way 3 cameras can be annihilated with poof balls before the robot is blind. Of course a simple protective cage with a window would work equally well, but if you're under budget why not go for the gusto?

Re: pic: 358 has four eyes!
Auto turret targeting. I keep telling them i dont want to have to aim this thing i just wanna drive around pullin 360's so the camera's get to target and do all the work for me.
i wish. |

Or, this COULD be a picture of 4 cameras mounted to their 2004 robot designed to keep you all busy talking about it instead of working on your own vision systems...
just sayin... |

As to overkill, we could use one camera to track each opposing robot and one for the center goa. |
