On a distant planet covered mostly by water a species of highly intelligence cephalopods have evolved and even developed space travel. The problem?
Most other species are land dwellers and the cephalopods need a means to traverse their space stations and cities. Without a skeleton of their own their land travel is limited to an undignified and uncomfortable crawl that is entirely unbecoming of the most ingenious species in the galaxy.
The solution? Build their own skeleton. An exoskeleton specifically. Ideally one that can be powered by the cephalopod's own muscle strength.
So my question is; Would it be feasible for a cephalopod to move on land by inhabiting a non-powered exoskeleton and moving the limbs with their tentacles. In my mind it works by the cephalopod entering the tightly fit exoskeleton, which provides the creature support enough to not collapse under gravity, and use their own flesh in place of the muscle tissue normally used to move the skeleton around.
If this combination wouldn't be functional what would be a way to make it functional? Preferably keeping with the non-powered artificial exoskeleton concept.
