With the growth of robotic applications in manufacturing, e-commerce order fulfillment, and other pick and place applications, there is a push for enhanced manipulation capabilities of robot grippers. This is the case especially with collaborative robots, which require robot grippers that can handle a widening variety of objects in fast, repetitive tasks.
The needs of the automotive, electronics, and food processing industries have propelled the development of claw, parallel, rotary, magnetic, and vacuum grippers. Besides consumer-packaged goods, various types of robotic grippers are used in the pharmaceutical, plastics, and agricultural industries. New specialized fields for robots include undersea exploration, telesurgery, and hazardous materials handling, all with their own gripper needs.
Robot Grippers Are Customizable
Robot grippers must be properly sized for the size, weight, and hardness of the items they handle. The required precision of the application must also be considered. Designers must review the demands for cycle time, torque, and safety limitations of force applied.
Contact points, wear, and exposure to environmental contaminants also influence engineering and design. Many companies offer customizable end effectors, the part of the robot that interacts with its environment, for specific materials. Easy-to-use end effectors that can easily be removed and replaced have been developed.
Robot Grippers Have Improved Dexterity
By means of new materials and types of grippers, robots are more reliable and flexible than ever. Three-finger adaptive grippers minimize the tool changes required. The implementation of six-axis force and torque sensors have added further intelligence to the movements of grippers. Force sensing has improved the grippers’ capabilities to manipulate fragile items and are often used in applications where the gripper is working close to humans.
Robot Grippers Add Intelligent Sensors
Machine learning, fed by datasets and connectivity, also shows great promise for grippers. Artificial intelligence, enabled with machine vision, instructs grippers how to approach objects. Robots are able to teach themselves through observation and comparison.
Robots are not only learning to compare objects to one another but can compare an object to the gripper itself and figure out the best method to move an object. Solutions have been developed so that an object’s properties and location can be determined from a single image, requiring fewer sensors and cameras mounted on the robot or in the environment.
Robot Grippers Combine Multiple Technologies
Some grippers are incorporating other technologies to create even better solutions. Combining vacuum grippers with fingers, computer vision, and machine learning can result in more reliable interactions. Some robots have been outfitted with two separate arms and different gripper configurations, allowing AI to choose which arm to use for a certain task, increasing both speed and reliability.
Continued advances in robot gripper technology are opening up possibilities for robot applications in an even wider variety of industries.
