ELECFREAKS Mechanical Catch (Use With Cutebot) is a gripper that uses an SG92R servo as a power source. The servo uses a PWM signal to drive the gripper gear to rotate and control the gripper for clamping and releasing operations. The structure adopts a design compatible with Lego 8mm round holes. You can combine it with other Lego components to build creative control structures, such as robotic arms, gripper carts, etc.

Because the opening and closing angle of the gripper is 90°, please control the rotation angle of the driving servo to 0°-45° (PWM: freq: 50Hz, 0°-45°(pulse:0.5ms-1ms)) to prevent blocking rotation. The steering gear burned out.

Jargon buster

Plain-language definitions for the technical terms used above.

MicroPython
A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
PWM
Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
servo
A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
