You need to find the most durable grippers for your robotic applications. What's the best way to do it?

Understanding the process is key for gripper selection. Also take into account future variations of the product that might be handled by the robot and avoid automated gripper changes wherever possible due to later problems in the process. The easier the best.

A key idea to consider is the variety of objects that need to be manipulated/picked up. If the variety is small it should be easy to find commercial grippers that are able to handle those items. If the variety is large, it would be more difficult since considerations of weight, size of the objects, materials, etc need to be made. Also, there are important considerations that could be made about the features that are required, e.g. compatibility with certain softwares, force control, payload, etc. The durability is usually linked to the fingertips rather than the gripper itself. As the grippers would be rated for a number of hours of operation and they are usually robust. Fingertips could degrade much more quickly.

To select the most durable grippers for your applications, it's crucial to thoroughly understand your application requirements. Consider the characteristics of the objects you intend to grip: their shapes, sizes, weights, and materials. Assess the frequency and speed of gripping and releasing actions needed in your operations. Additionally, evaluate the environmental conditions the gripper will be exposed to, such as temperature variations, humidity levels, dust, and potential chemical exposure. These factors influence the choice of gripper type, size, and material, ensuring you choose a gripper that not only meets your functional requirements but also offers the durability and reliability necessary for your specific robotic applications.

Steps to find the best durable grippers for robotic applications: 1. Know your application requirements, including object traits, task needs, and environment. Select a parallel jaw, angular jaw, three-finger, hoover or magnetic gripper. 2. Choose steel, titanium, nylon, PEEK, or composites. Also consider payload capacity, operation technique, and maintenance costs. 3. Compare choices using manufacturer websites, industry forums, and robotics specialists. Consider modularity for easy customisation and adaptation. 4. Try on different grippers before purchase to get the best fit. Ensure the gripper works reliably and correctly.

First you need to thoroughly understand the unique requirements and challenges of your specific application. By carefully assessing factors such as load capacity, environmental conditions, cycle speed, and precision demands, you can pinpoint the ideal gripper design and material that will withstand the rigors of your operational environment while ensuring optimal performance and longevity.

When in doubt test it out! Many gripper or EOAT companies provide free testing depending on the scale. Sometimes it is with manual manipulation or it could be robotic testing. This will provide a comfort level to progress forward with one technology type over another.

The proper gripper for your robot relies on item qualities, task needs, speed, precision, and environment. Parallel jaw, angular jaw, three-finger, hoover and magnetic grippers are common. Additional aspects include payload capacity, actuation mechanism, maintenance, and cost. Matching the gripper type to your application needs, considering modularity for future flexibility, researching and comparing possibilities from different manufacturers, and testing before buying may assure efficient and dependable operation while preserving your robot and its objects. Avoid one-size-fits-all solutions by considering modularity and researching several manufacturers before buying.

The most adequate type of gripper needs to be chosen depending on the items that are going to be picked up. The most common types are suction based grippers, since it is easier to design picking algorithms for those. They can pick up most of the items and are the most general solution. However, for particular items, they may not work and different solutions may be looked at. If you only want to pick up one type of item, it is an easier problem since you can choose or design a gripper specifically for that problem. If the variety is large, it could be convenient to test different grippers on the objects that have to be graspped.

Consider the requirements of your task and the characteristics of different gripper types. Parallel grippers are versatile, offer precise grip on a range of objects with significant force, making them ideal for tasks requiring high precision but less suitable for irregular or fragile items. Angular grippers are better for larger objects and can handle irregular shapes, but they might not match the precision of parallel ones. Three-fingered grippers offer balance, providing a secure grip for cylindrical or irregular objects. Vacuum and magnetic grippers are specialized; vacuum are excellent for smooth, non-porous items, magnetic are perfect for handling ferrous materials. Durability depends on type and quality of materials and construction.

When selecting the most durable grippers for your robotic applications, it's crucial to carefully consider the various types of grippers available and their respective strengths and limitations. By engaging in a comprehensive evaluation of options such as pneumatic, hydraulic, and electric grippers, alongside specialized designs like parallel and angular grippers, you can strategically match the gripper type to the specific demands of your application, thereby optimizing durability and overall operational efficiency.

The correct gripper material relies on object qualities, task needs, and environmental conditions. Grippers are made of steel, aluminium, titanium, nylon, PEEK, and composites. Other factors include cost, machineability, and upkeep. Aluminium is lightweight but corrodes, while steel is sturdy, durable, and pricey. Nylon, PEEK, and composites may distort at high temperatures yet are strong and wear-resistant. Additionally, composites require specialised machining. There is no "best" material, so adapt it to your application and environment.

The material selection of the gripper affects mainly two areas: - The fingertips -The body of the gripper The main consideration when it comes to the body is the weight of the gripper, impact resistance and corrosion resistance. When it comes to the fingertips, there are many other variables that should be considered. If you are manipulating food elements, the material will need to be food safe. It is also important to chose materials that are robust and not going to deteriorate quickly wich is sometimes a difficult tradeoff with the compliance they need to have to grasp items properly. Finally the friction coefficient of the layer in contact with the objects plays an important role.

Selecting the best material for a robotic gripper is a trade-off between durability and application. Metal grippers, strong and rigid, are ideal for heavy-duty tasks but risk damaging delicate objects. Plastic grippers offer flexibility but may not endure high forces or temperatures. Rubber grippers provide excellent cushioning and grip, suitable for fragile or slippery objects, degrade over time. Composite grippers, blending materials like metal for strength present a balanced option, ensuring durability protecting the gripped items. The decision needs to be on the nature of the objects, the operational environment, and the required precision and force, ensuring the chosen material aligns with these factors for effective performance.

When seeking the most durable grippers for your robotic applications, the choice of material plays a vital role in ensuring long-term performance and reliability. Through a meticulous assessment of material options such as steel, aluminum, and various polymers, consider factors like strength, corrosion resistance, and weight to determine the best material for your gripper. By aligning the material properties with the operational demands of your application, you can secure grippers that offer the utmost durability and resilience in your robotic operations.

Thorough testing and evaluation are needed to optimise gripper performance in robotic applications. Define evaluation criteria such grip success rate, payload capacity, force capacity, speed, precision, adaptability, and durability and wear. Use static load testing, dynamic load testing, object manipulation tests, environmental testing, and vision system integration. Force sensors, pressure sensors, and vision systems can evaluate gripper performance. The data can reveal gripper design and operating strengths, limitations, and areas for development. The insights can improve gripper design, material choices, and control algorithms. Multiple tests are needed to verify changes and optimise performance.

Testing and evaluating gripper performance is vital for ensuring durability in robotic applications. Conduct load tests to gauge weight handling, cycle tests for endurance, impact tests for shock resilience, and environmental tests to assess performance under varying conditions. These assessments check the gripper's capability in handling objects, its longevity, and ease of maintenance. Comparing different grippers on cost, quality, and reliability is also crucial. This helps choose grippers that meet specific needs while offering durability and efficient operation, enhancing the overall efficacy of the robotic system.

Building on Jake's advice after researching commercially available end of the arm tooling and you believe that none of them might be a right fit for your application reach out to the manufacturers directly as they can offer customised solutions. Look at the offering of various systems integrators and as well as broader tooling manufacturers as many of them offer customisable or bespoke EOAT solutions. Before jumping to the design of bespoke solutions internally, look outside first as there is a very high chance that someone dealt with a similar problem.

Robot grippers depend on their use and duties. Parallel, angle, three-finger, hoover, and magnetic grippers are common. Parallel jaw grippers work for simple, uniform shapes and pick-and-place activities, while angular grippers work for irregular shapes and high-force applications. Three-finger grippers work for intricate forms or delicate surfaces but not high-speed operations or huge or awkward shapes. Flat and porous surfaces with enough air permeability work well with hoover grippers. Magnetic grippers work for ferrous metals and fast pick-and-place. Knowing gripper types' strengths and weaknesses and your robot's application ensures efficient and reliable operation.

don't forget to plan for gripper maintenance intervals. Choose and set these in advance to avoid trouble with wear and problems that occur over time. Start by setting tight intervals for the beginning and loosen them while you learn more and collect more data on this special use case.
