featherweight flipper systems

With FP , a low powered system still delivers a few 100kg
Surface of piston in cm²*pressure of CO2- 55bar= force in Kg.
Meaning a 40mm piston delivers 690 kg. - relative losses , give or take 600kg .

The 12oz bottle we use in Hannibalito III weights in at a hefty 1.1kg full.

A Burkert 5404 (reasonably affordable solenoid valve that can do the job) weights 660 grams.

Ram (40mm bore*80mm stroke), collector and buffertank, with PRV and dumpvalve, can be done in 2 kg

4.5 kg to 5 kg is a reasonable weight for a full weaponsystem.

Are linear actuators worth the investment for a rear hinged lifter? I cant imagine they are very fast?

[Laser]

I used a home made linear actuator and it was quite slow, but it worked

[mattsdragons]

if you found one with a good amount of stroke and force then it could work

[Laser]

easier and cheaper to make your own.

[mattsdragons]

you would have to get a good drill though to get enough speed to make a good one though

[Danjr1]

Would make a cr@p srimech though wouldn't it?

[mattsdragons]

It would probably be fairly effective, just wouldn't have the same power as a gas system

[jonny]

you'd be able to lift people and turn them other but you'd nether have the speed flip them with an actuator

Weighed the robot and it's coming in at 8kg so a flipper looks possible now!
