Could a planet different to ours support this species?

(I have tried to fix this question as best as possible with the help provided from the staff of the site.)

I have started to develop my own crustacean species that resembles ants slightly. I would like this species to be humanoid in physique with a height around 1.2 meters (3 feet)

I was wondering if such a species could exist on a planet, I have thought of a few possible obstacles:

If this species had a thicker shell covering the body, this would very likely be heavy and would require an inner-skeleton support system to support the weight. A thicker shell would be a lot heavier with the sturdiness with it too, but with having a thinner shell to save weight but this would be more brittle and fragile. Having this shell would also need a muscular system regardless.

This inner-skeleton support could allow it to forage around for food on beach areas with a stronger muscular system.

I was also thinking of having the species evolve basic sapience, allowing them to be somewhat primitive and to use some basic tools to gain a few abilities.

What different elements would this planet need to support such a species like this? Any comments on my ideas would be appreciated. :) Thank you
