Right Arm Parts

Keep right arm parts separate from left arm parts. Retain the 12 M4x45 socket bolts with the completed arm: they are used during torso installation and are not counted again in the torso checklist.

Quantities are based on the assembly instructions, not a verified shipping manifest. Check the full quantity before ticking a row; leave uncertain items unchecked.

	Double-ended XT30 (2+2) cable - 230 mm Connected to ID 21 in Step 9; its free connector is connected to ID 22 in Step 12, not a new cable. Assembly references forearm assembly / step 9 forearm assembly / step 12	1
	WAGO connector Connector model is unspecified. Assembly references upper arm and forearm connection / step 13	4

Hardware

Count the hardware and keep it in labelled bags or compartments. Laying out every bolt is optional; checking its quantity is part of this checklist.
