Cannot remember that game

I remember playing a game years ago, where I had to control a small builder robot/module on a strange planet.

The robot had to build (and upgrade?) facilities in order to be able to power itself. I also remember something with containers it was able to manipulate.

Also, the game was in 3D.

Kind of vague? That's how I feel.
Any ideas?

Vortrex?

I don't find anything with this name :/

I also remember a level where I had to escape or kill giant alien spiders or something like that...

If you were speaking of Vortex from Argonaut Game, it's not it.
By the way, I played it on PC.

Found it. It was COLOBOT :D

sounds like lostbot.exe
