Ok, here are some proposed rule changes to make the offending robot leagel.
These rules apply to all open system robots. Closed system robots use the standard FRA or RFL rules.

Just to kick things of
-- Standard UN modified Soda stream bottles and valves and flow restrictors containing no more than the maximum rated weight of gas.

--The ram must have exhaust ports of XX area so at the normal working extension as assembled in the bot the ports are below the piston and can therefore vent the gas.

--The ram must be locked in the extended position whenever the gas bottle is fitted. It makes no difference if the bottle is full or empty. Apart from when it is in the arena. Or EO designated test area.

--A suitable low pressure blow off device, e.g. vac hose or spring-loaded valve installed at inlet of ram.

--Damage to CO2 bottle as for closed system rules.

--Mounting of CO2 bottle as for closed system rules.

---Electric operated CO2 valve must be spring loaded in off position .


I guess we get to remove the gauges and manual valves from our robot.
