End-Effectors & Tool Changers
End-effectors are tools attached to the end of a robotic arm to interact with objects. The most common types include mechanical, electric, pneumatic, and magnetic grippers, each suited for specific applications. Their selection depends on object size, fragility, required precision, and industry needs.
Two-Finger Parallel Gripper
This is one of the most common industrial grippers. With two jaws moving in parallel, it provides a simple, reliable, and cost-effective solution for handling small, flat, or symmetrical parts.
How it Works:
Linear actuation moves fingers in and out. Actuation may be pneumatic micro-gripper (fast, strong) or servo-electric grippers (precise, adjustable).
Advantages:
- High repeatability, consistent grip
- Simple and robust design, low cost
- Easy integration with robotic arms
Applications:
- Pick-and-place in assembly and logistics
- Machine tending (CNC, molding, inspection)
- Packaging and palletizing
- Laboratory automation (vials, test tubes)
- Education & research robotics
Servo-Electric Adaptive Gripper
These grippers use servo motors with feedback sensors to precisely control force and position. They adapt to varied shapes and delicate objects, making them ideal for collaborative robots and precision industries.
Adaptive Features:
Programmable grip force, sensor feedback, intelligent control algorithms.
Role of Sensors:
Provide force feedback, position sensing, object detection, and adaptive response in real time.
Advantages:
- Gentle, precise handling of fragile items
- Position accuracy and repeatability
- Safe for human-robot collaboration (force limits, soft grip)
- Easily reprogrammable for different objects
Applications:
- Cobots in assembly lines
- Medical and pharmaceutical handling
- Food & beverage packaging (fruits, eggs, baked goods)
- Quality control and inspection with vision systems
