Arm Joint parts and their functions

4 top-level parts · 29 parts in total · full bill of materials below

#	Part	Qty	What it does
1	Servo Motor 4 parts	1×	Brushless motor with an integrated encoder or resolver, driven in closed loop to hold commanded position, speed, or torque precisely.
2	Helical Gear Pair	2×	Two meshing helical gears forming one reduction stage that steps torque up and speed down between parallel shafts with quiet, continuous tooth contact.
3	Ball Bearing	2×	Deep-groove radial ball bearing.
4	Joint Encoder	1×	Encoder reporting an arm joint angle.
