In order to extend around and grasp items from different angles, angular grippers have fingers that can expand and close at an angle. This versatility truly shines when manipulating objects with unusual shapes or when more stability is needed.

3. Suction grippers:

Suction grippers are perfect for handling smooth and fragile surfaces, such as plastic or glass, because they use pneumatic suction to grab items. In order to lift and place objects efficiently, they work by creating a vacuum between the gripper and the object. The packaging and assembly industries make extensive use of suction grippers.

4. Soft grippers:

A secure yet delicate hold is assured by soft grippers, which are made of flexible polymers that can mold to the shape of an object. Since they mimic the skill of a human hand, they are ideal for handling fragile objects like fruits or electronics. Also, they can change shape to fit different objects, therefore, they reduce the likelihood of harm occurring during manipulation.

5. Magnetic grippers:

The application of magnetic force to secure metal materials makes magnetic grippers ideal for moving metal components. Industries like manufacturing and automobiles often use these grippers since they allow for the safe and quick handling of metal parts.

How do robotic grippers work?

In order to choose the best robotic gripper for a certain application, it is crucial to understand how they work.

A primer on functionality:

Robotic grippers leverage hydraulic systems, pneumatic systems, or electric motors to drive mechanical motions. Based on the architecture, they can open and close in reaction to environmental sensors or preprogrammed instructions. The precision of these movements is essential for the accurate positioning and manipulation of objects.

Here are the main parts of robotic grippers:

There are many important parts that make up most robotic grippers. The main parts consist of the following:

Jaws or fingers: The part that makes direct contact with the object being handled.
Actuators: The motors or pneumatic cylinders known as actuators control the opening and closing of the gripper.
Frame: The frame is the main structural part of the robotic arm that holds the gripper and the arm in place.
Sensors: These are optional parts that are used to measure the position of an object, the strength of the grasp, and whether or not an object is present.

Benefits and applications of robotic grippers

Robotic grippers have many benefits that increase the effectiveness and efficiency of automation processes.

1. Improved accuracy and precision:

The remarkable accuracy with which robotic grippers carry out their tasks is one of its most appealing features. Sorting, packaging, and assembly are all processes that benefit from this capability’s decreased error probability. Due to the delicate nature of the objects and the difficulty in controlling them, it is crucial to use the correct amount of force while handling them.

2. Enhanced effectiveness:

Robotic grippers can greatly increase output since they do repetitive tasks much more quickly. Hence, production lines may run continuously without resting because workers don’t get tired. This steady operation boosts efficiency and production by freeing up human workers to focus on more complex jobs.

3. Application flexibility:

A variety of industries can benefit from the automated grippers, including manufacturing, healthcare, logistics, and food processing, thanks to their vast assortment of designs. Assembly, packaging, and surgical procedure support are just a few of the many sectors that rely on robotic grippers.
