Re: How to bypass/replace the VRM
As others have said, try to use the older regulators if you can.
If it's a cRIO era robot with a PDB, AND you're not planning on working it too hard then you can potentially use the regulated outputs on the bottom of the PDB. This should work absolutely fine until you start moving. However if you've got a lot of heavy current draw motors, then you can potentially brown-out and lose power to these outputs. Use at your own risk.
Anecdotally, for a reasonably geared tank drive with 2-4 CIMs, I haven't had a problem with this "hack".
