Application of multi-dimensional force sensor in the robot industry

With thousands of years of evolution, humans have learned to walk upright and learn to use tools. In order to adapt to complex and diverse environments, human beings also have powerful and sensitive sensory inputs, relying on the interaction of various senses, humans can Complete a variety of tasks, so today's technology is developed today.

In general, robots are not tactile, but they can also “evolve” out of touch and benefit from touch. By giving the robot a multi-dimensional force sensor , the robot can have a sense of touch and manipulate the object in a simple environment without losing the precision and sensitivity.

Most robots designed for collaborative applications have built-in force and torque sensing to ensure safety, especially when working close to or directly with humans. But that's not enough, because we humans like to give dull, repetitive, dirty and dangerous tasks to those mechatronics robots. Therefore, we pay more attention to independent or integrated multi-dimensional force sensors that can achieve real work. Only by integrating these high-end sensors into mechatronics robots can we achieve our goal.

Thanks to proven sensor solutions, new designs and intelligent software, we have realized the technology that robots can touch and “feel”. In robotics, vision and touch are complementary ways. According to industry experts, touch sensing will soon be added to mainstream robotics applications like visual technology.

In machining, such as grinding, deburring, grinding and polishing, it has been very complicated for the robot to do this. You need to do a lot of programming according to the volume of the space, and it takes a lot of time to correct the error. However, with the integrated multi-dimensional force sensor, the sensor's path recording function allows the operator to simply grasp the arm end device and perform the desired movement. The sensor records the force and direction applied by the operator and the robot can repeat the operator's actions. This will greatly improve work efficiency and will help to ensure the safety of operators.

In addition, multi-dimensional force sensors also help with product positioning, product testing, product packaging, and robot assembly.

For example, precision assembly such as piston assembly or gear assembly is a common application for multi-dimensional force sensors. These precision-mounted operating planes are not only vertical or horizontal. In some installations, the operating platform will be accompanied by a certain angle. These will bring great difficulty to the actual assembly, and it is difficult to guarantee the accuracy. . The difficulty in actual assembly is not only the case. The accuracy required for the current application is limited to the visual technology. Because there is a gap between the parts during the actual assembly, and the gap is only one tenth of the diameter of the human hair, it is only by visual technology. Still can't be perfectly aligned. Therefore, in these practical applications, adding touch is the only way to achieve perfect assembly.

Today, with the rising labor costs in China, automation will bring benefits to enterprises. In addition to heavy-duty machining tasks, small component assembly tasks that rely on human finger touch, such as cell phone or computer assembly lines, can be tactilely assisted by humans or independently by adding multi-dimensional force sensors. Will greatly improve production efficiency.

Robots with multi-dimensional force sensors have a sense of touch, and they become more powerful and can do more complex, dull or dangerous work that should have been done manually. Enterprises, especially small and medium-sized enterprises, will continue to benefit from it.
