Catch is a gripper that uses a 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.

I need to build arm with gripper for small robots to be 3D printed.
The M5 catch unit avoids printing small pliers which are often inefficient and stable.

I've tested these for motion etc, but have not actually used one on a job so far.
