The FRA build rules basically predate the Robot Wars rules for hydraulics. Robot wars requires a test point to eliminate the possibility of a team cheating.(new for series seven)
The FRA have assumed that roboteers are above such things and therefore no need to check pressures. Most robots have gear pumps fitted which are usually rated at 210 bar max, this point has been missed by the Robot Wars rule makers.
We do insist on a recognisable system relief valve for the open circuit which Robot Wars does not.It is our belief that Robot Wars are not concerned enough with what roboteers do in their garages, testing safely etc.
Should you wish to compete on both tv and the open circuit you will need both the relief valve and a test/gauge system.

We have a proposal to raise pump pressures up from 3000psi to 5000psi in line with America.
This Item will be up for discussion at our next meeting.
This proposal may if ratified will effectively offer disqualification for these uprated machines.

My own view is that a figure of 4000psi should be used, as it is the absolute maximum of an aluminium gear pumps pressure range. Someone has then to persuade the Robot Wars rule makers to allow for this increase to enable hydraulic robots some future development potential
