The pneumatics are not to hang. They are used to prevent the robot from falling back down after motor power has ceased to be applied A.K.A. the end of a match.

We went back for a second analysis, it's probably about 15, yes. We'll have an exact weight on here tomorrow.

15 will possibly be the minimum because two cylinders will weigh about 2 pounds

I am fairly certain that the tanks weigh .5 lbs each.

Yeah, the vex website lists them at .68 lbs each, so you're a bit closer.

If you plus pistons, tubings, screw, nuts,,,,, it will add up.

Re: 944A Bionic Bayhawks "Asgard" MK. III Reveal

Sooo....... you have 2 reservoirs on your robot but only fire one piston once in an entire match? o.O Am I missing something? You could just use a long coil of tubing to store enough air for one action in a game, or even better, you can skip the coil of tubing and just have the piston filled before the match, then you don't need to "store" any air at all. Just release what the piston already has. When you get pneumatics to hold the robot when hanging though, you will need to store air in some way (to save weight, I'd recommend the coil of tube).

Unless the piston on your intake is doing more than just releasing the intake? Perhaps tossing the large balls a little bit?

As it stands right now, the 8 bar you built doesn't give any more height than a similar 6 bar (refer to attachment). If the height you have if sufficient, then I think you should switch to a 6 bar for reasons like friction, ease of maintenance.

Actually they are getting about 5 extra inches of height as the bottom bar of the linkage indicates how high it would go and the 8 bar provides more height.

Not exactly, their 8 bar stop early because they have that c-channel sticking downwards. Notice their 8 bar and the 6 bar I drew have identical ranges of motion. You can even imagine them being both on the robot at the same time to see why this is true.
