Any restrictions on the camera?
My team plans to use a rasberry pi camera and I was wondering if there was any restrictions to what camera we are allowed to use?

Re: Any restrictions on the camera?
I don't believe there are any restrictions on what cameras you can use as long as they do not draw more than 7mbs. The 7mbs limit will be strictly enforced this year.

I'd recommend configuring your camera settings to stay well under the 7Mbps or you'll likely experience lag. There are some notes from FIRST here: 2017 FRC Control System FMS Whitepaper |

Re: Any restrictions on the camera?
The bandwidth limit only applies to what goes back to the driver station. You can saturate a gigabit link from the camera back to your roboRIO all day long if you want. Granted, that would take like 25 10 megapixel cameras and your roboRIO would never be able to process that much image data.. but legal!

Don't forget the COTS parts cost restrictions as well, just in case you're considering something super fancy.

Re: Any restrictions on the camera?
The 7mbps limit is actually imposed by the radio on the robot. Yes, the traffic is VLANed, but the rate limiting is applied before the packets hit the air. The intention is to reduce the potential for wireless saturation and interference. Applying the rate limit further upstream doesn't have that effect.

Re: Any restrictions on the camera?
It's from a few years ago, but here is a screensteps about measuring your bandwidth usage:
http://wpilib.screenstepslive.com/s/...andwidth-usage The majority of bandwidth tends to be taken up by camera streaming, and if you view it with the default dashboard it also displays bandwidth. Last edited by Mark McLeod : 16-01-2017 at 09:59. |
