Voltage divider

[andreboos]

What is a safe way to divide voltage on an FRC robot?

I'd like a relay to drive a motor at far less than 12 volts. According to the wikipedia page, the voltage of a resistive voltage divider would vary with the load, and I'd like to keep it stable. Additionally, the resistors would have to be rated for multiple hundreds of watts to be FRC legal, and those that I can find are expensive and bulky.

Edit: Does R47 prohibit resistive loads between a relay module and a motor?
