Unit Catch is a gripper powered by the SG92R servo motor. The servo uses a PWM signal to drive the gear rotation, allowing control of the gripper for gripping and releasing actions. Structurally, it features a design compatible with LEGO 8 mm round holes. You can integrate it with other LEGO components to build creative control structures such as robotic arms and gripper vehicles. Rotation Angle Since the opening and closing angle of the gripper is 90°, please control the servo rotation… (M5Stack U102)
