I was just about to correct my analysis (after blowing up the photo to see it better) when I notices that Lil' L just called me out.

Ah well... ...it is hard to argue with the truth.

A typical gas strut about that size has a stroke of about .2m and has a force of about 1000N. That means each spring is packing 200Joules. They've got 4 of them so it should be able to provide 800 joules or so. Plenty.

Very good,

I have another question. How do you tie the front an the back together? If I am a very heavy robot in front and light in the back will you lift me still or will the platform $@#$@#$@#$@#?

Do Tell.
