Re: Yet Another Vision Processing Thread

Any suggestions for a 12V-12V converter? Anyone have some results on issues with voltage stability with Odroids or other SBCs?

By the way, Hunter, how do you prevent your ODROIDs from corrupting from the rapid power-down? Do you have a special mechanism to shut down each node? Also, which converter are you using to power the Kinect? I don't think it would be wise to connect it directly to the battery/PDB, etc. You'd need some 12v-12v converter to eliminate the voltage drops/spikes!

As for your query of multi-noded, I think you are misunderstanding what he is doing, having a computer for each of the 3-4 cameras onboard the bot. Hunter will probably just use regular UDP sockets, as he said in his post. Either one UDP connection per XU can be used to the cRIO, or maybe there can be a master XU, that communicates with each slave XU, processed what they see, and beams the info to the cRIO!

However, I think it is still overkill to have more than 2 onboard computers, except the cRIO!
