#	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	Telescoping Spline Shaft	1×	Central spline shaft that extends and contracts while transmitting rotation.
3	Universal Joint	2×	shaft end couplings
4	Encoder	1×	Rotary or linear sensor that reports position and speed of a shaft or axis as electrical pulses or absolute position data for closed-loop control.
