Their scaling mechanism is a long inflatable tube with a hook at the end!

We had an idea like that but decided that it would have failed inspection under R77 and as clarified by Q688.

• A. Items available in the KOP (except as noted in R77-K),
• B. Pneumatic pressure vent plug valves functionally equivalent to those provided in the KOP,
• C. Solenoid valves with a maximum 1/8 in. NPT, BSPP, or BSPT port diameter,
• D. Solenoid valves that are rated for a maximum working pressure that is less than 120 psi rating mandated above are permitted, however if employed, an additional pressure relief valve must be added to the low pressure side of the main regulator. The additional relief valve must be set to a lower pressure than the maximum working pressure rating for the solenoid valve,
• E. Additional pneumatic tubing, with a maximum 0.160 in. inside diameter, functionally equivalent to that provided in the KOP,
• F. Pressure transducers, pressure gauges, passive flow control valves (specifically “needle valve”), manifolds, and connecting fittings,
• G. Check valves, provided that the requirements of R89 are still met.
• H. Shutoff valves which relieve downstream pressure to atmosphere when closed (may also be known as 3-way or 3-way exhausting valves).
• I. Pressure regulators with a maximum outlet pressure of no more than 60 psi,
• J. Pneumatic cylinders, pneumatic linear actuators, and rotary actuators,
• K. Pneumatic storage tanks (with the exception of White Clippard tanks P/N: AVT-PP-41), and
• L. Compressors compliant with R79.

• A."Inflatable pool tubes" are not included as pneumatic items that are allowed on FRC ROBOTS in R77.

I don't know how 4060 did this, but we were considering a coiled wire or tube inside the inflatable that kept things from getting too far out of hand. Our first iteration would have been with a piece of lightweight dryer vent tube.
