My triactuator

Here's an idea of a actuator type i had...

its not scientifically tested.. but what i like in this is that the weight rest of the screw and hardware... not of the motor...

Please comment/critic as you like... it certainly can be improved...

below is the design of 1 actuator...

I like the screw actuation, nice idea. Very ingenious.
I thought of a triangle frame once, that was actuated by air bags from a scrapped air-suspension system. It would have limited movement unless coupled with a 3:1 cantilever system.

I also think screw actuators are the most solid ones... since we kinda of use "domestic" hardware, i might be the most secure...

using 3 actuators like this should give me roll, pitch, acceleration and deceleration plus a up and down feel...
