Mechanical Arm

Mechanical Arm is a machine used to automate part of a colony’s item handling. It belongs to Core Keeper’s machinery system, where connected devices can take over repetitive work that would otherwise require manual interaction. In practical use, it is one of the core tools for building automated production lines and resource-moving setups.

A Mechanical Arm is most useful anywhere items need to be transferred between storage, processing stations, and other machinery. By arranging arms as part of a circuit, a player can reduce the need to move materials by hand and keep nearby workstations supplied continuously. This makes it especially valuable for base logistics, crafting chains, and other repeatable tasks that benefit from steady item flow.

Typical uses include:

• moving items between containers and machines
• feeding materials into automated setups
• helping sort or redistribute resources within a base
• supporting production chains so machines do not sit idle

Because it is part of the game’s machinery system, the Mechanical Arm is best understood as a utility component rather than a standalone production building. Its value comes from how it is integrated into a wider circuit. The exact setup depends on the layout of the base and the task being automated, so the most effective approach is usually to place it where the item path is short and the transfer target is clear.
