M5Stack Catch Unit (SG92R) is a gripper that uses the SG92R servo as its power source. The servo uses PWM signals to drive the gripper gears to rotate, controlling the gripper for gripping and releasing operations.
This structure adopts a design compatible with LEGO 8mm round holes, which can be combined with other LEGO components to build creative control structures, such as robotic arms, gripper carts, etc
