I am a Carbon based three dimensional autonomous biped that at one point popped into existence

 on a big ball floating in space. All of my time here i've been running around on this ball doing meaningless things as eventually I will get inserted into the ball for recycling. The powers that be say

they will not insert all the crap i've collected during this time into the ball with me. ...Bummer

Besides collecting things, I try to keep a balance and make things for other beings to collect.

So help keep the balance of the big ball and buy my stuff!
