Assembly of the Camelot micro-extensometer system. (1) Connect the VINT Hub Phidget (HUB0001_0) to the Stepper Motor Phidget (STC1002_0) with a Phidget cable. (2) Connect the VINT Hub Phidget to the Wheatstone Bridge Phidget (DAQ1500_0) with a Phidget cable. (3) Attach the force sensor (Phidgets 3133_0 Micro Load Cell) to the Wheatstone Bridge via a wiring harness, match wiring colors, red for power, black for ground, and green and white for signal at the screw terminals. (4) Connect the Stepper Motor Phidget to the power supply (Mean Well GST25 A05-P1 J, 12 VDC, 2 A) with the correct polarity. (5) Wire the actuator (Befenybay 50 mm NEMA11 T6 × 1) to the Stepper Motor Phidget following the coil configuration (A +, A −, B +, B −). (6) Connect the VINT Hub Phidget to the computer using a Micro-USB-to-USB cable for data acquisition and control. (7) Attach the camera to the computer via USB for image-based strain tracking. (8) Secure the actuator stretching arm to the actuator. (9) Mount the stretching pin for mounting samples to the force sensor. (10) Fasten the actuator to the Camelot stage with screws. (11) Fix the force sensor to the Camelot base, routing the wiring to avoid sharp bends. This setup synchronizes actuator movement, force measurement, and optical tracking within the MorphoRobotX software. Scale bar: 30 mm
