- Section: Asimov › Asimov 1 › Assemble Asimov 1 › Preparation › Module Checklists

This checklist covers everything you need to assemble the right arm: main parts, actuators, and fasteners. Cables are counted together in the [Cables](https://docs.menlo.ai/asimov/1/build/assembly-preparations/part-organisation/cables.md) checklist.

Right Arm Module checklist: 21 required rows. Quantities are derived from the assembly instructions, not a shipping manifest. "Used in" links the assembly steps that use each item.
