This small gripper uses a rack and pinion design with a servo-driven pinion and opposing racks to keep the gripper paddles synchronised and parallel to each other throughout its 32 mm range of motion. It includes a special micro servo with an additional wire that gives access to its feedback potentiometer, so you can track the actual position of the gripper paddles. This is the same gripper used in the Robot Arm Kit for Romi, and assembly instructions can be found in the Robot Arm Kit for Romi User’s Guide. Please note that the full range of the Micro Gripper requires servo control pulses between 0.5 ms (fully open) and 2.4 ms (fully closed), which is well beyond the standard hobby servo range 1 ms to 2 ms, so you should make sure your control electronics is capable of generating such signals if you care about getting the full range. Due to unit-to-unit variations in the servos, you might need to adjust these values for your particular gripper.
