A Shaktool is a robot that is only found in room in the entirety of Super Metroid
It is not featured in any other game to date.
 Super Metroid
It's presumed purpose is to dig through super tough sand like material and this function aids Samus navigating through an otherwise impenetrable sandwall.
Once you get passed it, you will obtain the Spring ball in a few rooms to the right.
The Shaktool can be destroyed but always respawns when you reenter the room again.
