It's the U-Invent. With it, you can invent weapons and upgrades for your Bots as you would with special ammo in BioShock. If your Bot dies, simply invent another one. If you want to give it the same upgrades as before, you can reinvent them.

The Bot interface isn't going to be the same as the ammo interface within the U-Invent. Basically, what you'd do is that you can switch between the ammo and Bot interfaces in the machine by tilting your thumbstick (or, in my case, pressing the arrow keys) to the left or right. In the Bot interface, you can first select which Bot you want to upgrade, and then you can change its loadout. It's kinda like Power to the People, except you can always change your upgrades if you want.
