IF 700psi (or whatever you can run without blowing up) can't get throught it, I'd love to see what can.
I built that big robot on that TV show that time

700 psi?
If you're talking about Pneumatics then I'm sorry but my lifting arm is going to be electronic

The diagram kinda goes like this

Brushed motor -> Lifting arm mechanism

Brushless motor -> Gears -> Lifting arm mechanism

Linear actuator -> Lifting mechanism

Please bear in mind that the robot meant to be a featherweight

lol, he said Lifting arm

He was talking about my robot, which is a huuuuuge hammer, it had issues passing safety because of a check valve so I had to dial it way down.

The "easiest" motor gearing is a bit out of date, but will still work, windshield wiper gearboxes usually have decent worm gears and plenty of torque, just be careful with big impacts.  Beyond that ballscrews aren't that expensive but require some precision parts so they dont bind up.

Big impacts you say?
Hopefully most of the energy could be deflected, or at least absorbed by (what I am hoping is) going to be side-skirts  :facepalm:
But knowing there are horizontal spinners, it's going to be another Nightmare VS Slamjob to sound like the miserable BB fanboy that I am  :rage

Entirely depends on the material, the mounting and the structural strength of the rest of the bot. All things to consider :)

I'll have to focus on that when It comes to it, right now I guess I'll have to focus on trying to get the parts to make it mobile otherwise I'll just overwhelm myself

nearly all losses by newer builders aren't because of energy not being deflected or frames collapsing, its because when you get tossed or thrown or whatever, the mass of a plug or wire + the motion is enough to unplug some portion of your robot.

Tape or glue everything, then ziptie it TWICE
