Robotics Gripper Design in Robotics

A gripper (end-effector) picks up objects. Simple grippers use 1 servo to open/close jaws. Advanced grippers use multiple actuators for complex manipulation.

Servo-based gripper: servo at 0° = fully open, 90° = fully closed. Mechanical linkage transfers servo rotation to jaw motion.

Torque is critical: calculate force needed to grip the heaviest object, then select servo with sufficient torque rating.

#include <Servo.h>

Servo gripper;
const int gripPin = 9;

void setup() {
  gripper.attach(gripPin);
}

void grip() {
  gripper.write(90);  // Close
  delay(500);
}

void release() {
  gripper.write(0);   // Open
  delay(500);
}
