Everyone,
The Mercotac slip rings are not slip rings in the true sense of the word. They are mercury filled contacts and are not legal on FRC robots. If you read the application notes on these contacts, you will see warnings about mercury leakage when mechanically stressed or when max current is exceeded. I contacted the manufacturer and was told that those events are rare but do occur. Mercury spills on an FRC field will close down the event.
