Re: Example of Vision Processing Avaliable Upon Request

hello everyone. I am a team mentor for Team 772. This year we had great intensions of doing vision processing on a beagleboard XM rev 3 and during the build season got some opencv working on a linux distro on the board. Where we fell off is we could not figure out a legal way to power the beagleboard according to the electrical wiring rules. So my question to the community is, if you did add a second processor on your robot to do any function such as vision processing, how did you power the device?

We interpreted a second battery pack for the xm as not permitted because it would not be physically internal to the XM unlike a laptop which has a built in battery which would be allowed. The XM would have been great due to its lightweight in comparison to a full laptop. And if we powered it from the power distribution board, it says only the crio can be powered from those terminals, which we thought we would need to attach to in order to connect the required power converter. Remember there are other rules about the converter to power the radio etc. Besides, we did not want ideally to power it from the large battery because we did not want to have the linux os get trashed during ungracefull power up and downs that happen on the field. So, how did you accomplish this aspect of using a separate processor? So, in short we may have had a vision processing approach but we could not figure out how to wire the processor.

Any ideas?
