For signals, you could use something like a parallel port DB-25 to make a harness for that robot's sensors and pwm connections. You would solder all the leads to the appropriate pins on the plug(s). Last season, we used an aircraft-grade DB harness plug for our shooter deck.

For the cRIO and digital sidecar, you would keep them plugged together with a regular harness set. For power, we've put Anderson Power Poles between the motors and motor controllers for ease of rewiring.

We've used velcro on Baltic birch plywood to hold down all our motor controllers, cRIO, and digital sidecar.

What you are asking is actually a fairly good design practice for a competition robot, even if you had extra control system in your inventory. The ease of access and serviceability will save you a huge hassle later on.
