AsiaIndustrial NetNews: According to Futurism, it is common for humans, especially those who work in manufacturing, to tie a knot, strip the sheath of a cable, insert a pin into a hole, or use a drill tool. They all seem simple, but they also require the use of flexible hands and fingers to perform fairly complex movements.
althoughRobotThey are increasingly taking part in the production process in factories and are widely used for other types of work, including service industries and healthcare, but they are underwhelming with their agility and agility. Since humans brought robots to car factories more than 50 years ago, we have built many robots that weld, paint, and assemble parts. The best robots today can even pick items they are familiar with and move them elsewhere, such as removing products from warehouse storage bins and placing them in boxes.
But the Robot still can’t properly position the tools in its hand, such as aligning a Phillips-head screwdriver with a groove on a nut or hitting a hammer with a nail. They also cannot use both hands at the same time for complex tasks, such as changing batteries in a remote control. In contrast, human hands are very good at doing these jobs. For Robot hands to perform daily tasks with the same ease as humans, they need to become more flexible, reliable and powerful, while also being able to sense more precisely for finer movements. They first need to figure out what the target is and how to better grasp it. For robots that can work side-by-side with humans, we have to figure out how robots can help us, especially when we don’t feel like 2 hands are enough.
A team of researchers at Northeastern University is working on this kind of research, building a humanoid Robot similar to NASA’s Valkyrie. Valkyrie has 3 fingers and 1 thumb on each hand. Each finger has articulated joints, and each hand has a wrist that can be easily turned. Researchers are integrating arm, wrist, finger, and thumb movements to accomplish a task, such as using a wrench in a circle to tighten a screw, or pushing a cart from one place to another.
Instead of designing a robot specifically to perform a specific task, we need to design multipurpose robots, or “general-purpose robots,” that can perform almost any task. The key to the success of such robots is that they need to have an excellent pair of hands. Research at Northeastern University focuses on designing new adaptive robotic hands that can perform precise movements and also grasp automatically. When robots can hammer nails, change batteries, and perform similar actions, we can create robotic hands that are as mobile as human hands. Achieving this goal will also require inventing new designs that combine hard and soft elements, such as human bones that give the hands grip strength, and skin that distributes pressure to keep wine glasses from shattering.
Modern technological advancements are making the development process easier.have3D printingWith technical support, we can make prototypes very quickly. We can even experiment with different mechanistic arrangements using low-cost disposable parts, such as 2 or 3 fingers for simple picking tasks, or an anthropomorphic robotic hand for more delicate manipulations. These abilities have become human instincts through vision and proprioceptive abilities.
And when we can use them on robots, they can do a lot more, such as sensing if the grip is too hard, squeezing objects too hard, and so on. As electronic cameras and sensors get smaller, we can also take advantage of new ways to integrate them. For example, if we press down on the sensors and cameras on the robot’s hand, they send feedback to the robot’s controller to determine if the grip is safe, or if something starts to slip. In the future, a robotic hand may be able to sense the direction in which an object is slipping so that it can grasp the target object again.
Another landmark research will be to find new ways for robots to figure out what movements their hands need to make in real time, including feeling what’s going on in their hands at all times. If robotic hands can detect changes in the object they are grasping, or manipulate objects while grasping, they could help with common manual tasks like tying knots and stripping wires.
Two-handed collaboration can be more helpful, and it can significantly improve efficiency, especially in manufacturing.Robots that can operate drills with two hands or transfer machine parts with one hand are a huge advance, allowing factoriesautomationMore steps in the production process. Humans have yet to develop a similar system, but researchers, technologists, and innovators will do their best to develop human-like autonomous robots for the foreseeable future. But that won’t slow down the ongoing robotics revolution in manufacturing, where there is plenty of room for automation in current production processes to improve safety, speed, and quality. As robots become more and more perfect, they will become human’s true assistants.
