With millions of years of evolution, humans learned to walk upright, learned to use tools, in order to adapt to the complex and diverse environment, humans also have a strong and sensitive sensory input, relying on the interplay between the various senses, humans can complete a variety of tasks, so there is a technologically advanced today.

Cooperation between the various human senses is always going on. Think about how we use the key to unlock a door in a dark situation. First, we use our eyes to try to see where the keyway is, then we insert the key, but when the key is actually inserted into the eye of the lock, we do not look, but use our sense of touch to make the final adjustment until the key is inserted into the eye of the lock. This operation is very natural to humans, so almost no one will think about how the whole process is carried out.

Generally speaking, robots do not have a sense of touch, but they can "evolve" and benefit from it. By giving robots six-dimensional force sensors, they can have a sense of touch and manipulate objects in simple environments without losing greater accuracy 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 leave the dull, repetitive, dirty and dangerous tasks to the mechatronic robots. Therefore, we focus on stand-alone or integrated six-dimensional force sensors that can actually work, and only by integrating these high-end sensors into mechatronic robots can we achieve our goals.

Thanks to proven sensor solutions, new designs and intelligent software, we have made it possible for the robot to touch and "feel" the technology. In robotics, vision and haptics are complementary approaches. As a result, industry experts expect that touch sensing will soon be added to mainstream robotics applications, just like vision technology.

In machining, such as grinding, deburring, grinding and polishing, getting a robot to do these tasks used to be very complex, requiring a lot of programming based on space volume and a lot of time for error correction. But with the integration of a six-dimensional force sensor, using the sensor's path recording capability, the operator can simply grab the end-of-arm device and make the desired movement. The sensor records the force and direction applied by the operator, and the robot can then repeat the operator's movements. This will greatly increase efficiency and will help to ensure the safety of the operator's workers.

In addition, six-dimensional force sensors can help with product processing positioning, product testing, product packaging, and robotic assembly.

As an example, precision assembly such as piston assembly or gear assembly is a common application for six-dimensional force sensors. The operating plane for these precision installations is not just vertical or horizontal, but in some cases the operating platform will be at an angle, which makes the actual assembly very difficult and the accuracy requirements difficult to guarantee. The difficulty in the actual assembly is not only that, the accuracy required for this application is currently limited to vision technology, as there will be gaps between parts in the actual assembly, and the gaps are only one tenth of the diameter of a human hair, so the vision technology alone is still unable to achieve perfect alignment. Therefore, the only way to achieve perfect assembly in these practical applications is to add haptics.

There are various types of six-dimensional force sensors based on strain gauge, optical or capacitive technologies. Each technology has different performance levels, lifetimes, calibration requirements and costs. Among the many six-dimensional force transducers, the six-dimensional force transducer from RALT Technology stands out for its unbeatable performance and excellent cost performance.

The RIELT six-dimensional force sensor can measure forces and moments in x, y and z directions. The six-dimensional force transducer has a rugged construction, excellent non-linearity, high accuracy and high overload capacity.

In practice, the six-dimensional force sensor from RALT Technology has a very small deflection even when very heavy loads are applied. This is very important for robots, because many high precision robots require very precise tool center points, and trying to achieve this often requires a huge additional investment. If the sensor has a lot of offset under load, then this accuracy will no longer exist.

Not only that, but RALT is also able to package all the electronic components of a six-dimensional force sensor, including amplifiers, into a smaller package that requires only one cable to meet the power and communication requirements of the external interface.

In today's world of rising labor costs in China, automation will also bring benefits to companies. In addition to heavy machining tasks, small component assembly tasks that originally relied on the human finger touch to complete, such as cell phone or computer assembly lines, can be greatly improved by adding six-dimensional force sensors that enable robots to be given the sense of touch to assist humans or complete these tasks independently.

Robots with six-dimensional force sensors have a sense of touch, and they will become more powerful and can perform more complex and dull or dangerous tasks that should be done by humans. Companies, especially small and medium-sized ones, will continue to benefit from this.
