Robot Arm

Robot Arms are covers added by GregTech 5. They are also used to craft some of its machines.

They can be attached to GT Blocks with Inventories such as Item Pipes, Machines and Machine blocks.

They import items between the inventory they are attached to and the inventory they face. Other than Conveyor Modules they can import from an specific slot. Right-clicking with an empty hand on the upper-left or lower-right area of the cover raises or lowers the slot number by one respectively. Using a Screwdriver raises or lowers the slot number by 16.

The player can switch between the modes of a Conveyor Module using a Screwdriver.

They can be controlled via Redstone signals by using a Machine Controller attached on the same block.
