Re: Multiple Axis Cams?

I finally understand that the white Dlink goes on our robot, sorry that was a goof on my part. And we can use our own custom laptops for the driver station, so we could technically have a mozilla browser open to the ip of the camera, and just make that take up half the screen with the rest of the driver station take up the rest.

All signals must originate from the OPERATOR CONSOLE and/or the Field Management System, and be transmitted to the ROBOT via the official ARENA hardware. No other form of wireless communications shall be used to communicate to, from or within the ROBOT (e.g. radio modems from previous FIRST competitions and Bluetooth devices are not permitted on the ROBOT during competition).

So we can use a second camera if we put it our cots/bill of materials?

Re: Multiple Axis Cams?

I have also been contemplating a second camera. The ethernet port is there, but can I power it? The wiring diagram still shows the camera connected to the 5V supply on the PDB and you typically are not allowed to wire multiple devices to the same connector. Are we allowed to wire it as a custom circuit with a converter? I am still looking but I haven't seen anything yet.

Re: Multiple Axis Cams?

These are good questions for the Q&A.

Re: Multiple Axis Cams?

you can power it with a second side card i just want to know if you can do it?

cause if you connected a camera to the crio the clam can use it for the drivers. then if you cennect another to the d-link router your team mates could connect to it to watch the game from the camera instead of the stands right?

I really don't understand what you want to know. What is a "second side card"? What is "the clam" supposed to be? See if you can find someone to help you ask your question in a less cryptic fashion.

Re: Multiple Axis Cams?

okay there is the digital side card which you plug the pwms into.... that is not were the camera gets power...

The Digital Sidecar has absolutely nothing to do with the camera (except maybe to provide control to servos on a pan/tilt mount if you use one). The camera has its own dedicated 5 volt power connection on the Power Distribution Board.

Re: Multiple Axis Cams?

so then you couldn't have two camera's cause you would need two power distribution boards

Additional cameras would fall under the category of custom circuits. You can provide power to them using a 20-amp circuit from the Power Distribution (plus whatever voltage regulation they might require).

Re: Multiple Axis Cams?

T-junction wiring.

Re: Multiple Axis Cams?

mhmm that sounds like fun T-junction i might have to try that

Re: Multiple Axis Cams?

Yea, we did that to the cRIO last year and the solenoid breakout.

Re: Multiple Axis Cams?

how hard is it to do?

and how safe is it?

Re: Multiple Axis Cams?

I'm not sure about safety, but all you do is take another wire, put it across the main one going to your first camera, and solder it in a T-splice.
