Goldstar for a clean layout!
To add to the above, the robot rules only allow one primary regulator. You can place a second regulator downstream if you intend to use air at less than 60 psi.

R71 “Working” air pressure on the ROBOT must be no greater than 60 psi and must be provided through one primary adjustable,
relieving, pressure regulator.

As to the use of Power Locks between the PDP and controllers, I second the previous post. The connectors just add another point of failure, more resistance and cost. They are nice, but in the event that you need to replace a dead controller, they would only save a few seconds over wires inserted in the PDP.
