With the recent release of robots there has been confusion with how to build robots. You will need to follow these steps

1) Buy a mining robot from the store. You can buy up to 3 I think.
2) Go to missions and select a mission to do. Take out your mining robot when you see a rock and double tap it when it is next to the rock. It will auto mine the rock and pick up the mineral for you. (you take out a robot by going to the menu with friends list, facebook and all that jazz, then tap the robots tab)
3) You must finish the mission to keep any minerals your bot has mined. If you die/fail, you will lose your minerals from that mission so always clear out the NPC's before mining.
4) When the mission is over, head over to the robot shop again and take out your bots you used to mine. You then have to tap the transfer guy and he will put the minerals from your bots into your inventory.
5) Go back to the robots tab, and instead of picking a robot, go to the bottom right where it says build.
6) Here you can see what minerals and how many you need for the robot you want depending on your class. Once you have enough minerals you can build your bot.

Other stuff:
You can name your bots
Every time you use a bot, it looses "health" and will eventually break
You can drag your bots, or have them follow you
Some minerals you can only get by destroying space ships and power plants

If you have any further questions, leave them here. Happy mining/building!  

You can also make your robot named Nico (GP Admin) and have a 'little admin friend' follow you around. The possibilities are endless!  

not the era shovel again. we should be able to charge the bots, but you have to not go afk and go online while doing nuthin but charging  

Will the bot lose health while it's following you?  

So many people abused the naming system. Some were funny though, like mine and slash's robots.  

I bought 5 bots and was about to do mission and then someone called me so I had no volume when I went back to zone and I double tapped the home button and exited the app out from their and I relogged onto the app and the next thing I know I only had 2 bots what the heck happened?!? When I exited out the app I had the three bots following me. Please help I want my three bots back!!

Check your bot inventory  

You will most likely have to keep updating your bot or repairing them with minerals like rusty guns on era, if not they break. I think that is the plan, not sure however.

You think I didn't do that? 3 of my bots are gone (( I spent money on them  

I will look into if bots go away if you log out

Oh i'm sorry, I take things the wrong way some times. I had 0% Lag.  

hmm have had many reports on this, but it does not happen to everyone. Stefan says he will take care of bugs and improvements tomorrow. Dunno about refunds though x-x so for now just make sure you put away bots properly.  

I'm excellent at finding bugs. I shall post back if there is anything. Perhaps I can even try to place more than 3 bots at a time.
