The bot comes issued with two simple commands "Tunnel" and "Tower". You can find hours of entertainment (or frustration) trying to work out the alien symbols and putting them into commands. In theory the Bot can do anything you can do, but you might end up with a headache trying to work out the codes for them. The bot can mine any material than the player will ever be able to mine, even if the player doesnt have the pick to allow them to do so yet.
