Multi-Axis Force Sensor vs Single-Axis Force Sensor: Choosing the Right Solution

The robotic arm on your factory floor? It looks smart. But it can be pretty clumsy without the right feedback. Think about it, trying to plug in a USB cable. A simple push might work. But if the port is a bit off? The arm starts to twist and jam. It is fighting by itself; it has little to feel. This is the core of the issue.

Choosing the wrong force sensor is like giving that robot poor eyesight. Everything gets slow, clumsy, and expensive. So how do you pick? The simple single-axis sensor? Or the more complex multi-axis type? This isn’t just a technical choice. It’s a business one. Get it right, and your project runs smoothly. Get it wrong, and you face delays and wasted money.

We are going to pass through the actual distinction of these sensors. You’ll see clear examples. And you’ll get a straightforward checklist to make the perfect choice for your needs.

The Big Idea: One Direction vs. Every Direction

We shall leave this out of the book. Visualize forces in some sensible manner.

A single-axis force sensor is a one-trick pony. And that’s its greatest strength! It measures force in one single direction. That’s all it does. It answers a simple question perfectly: “How hard is something pushing or pulling in this straight line?” A great example is the scale in your bathroom. It only measures how much you’re pushing down on it. Nothing else.

Now, a multi-axis force sensor is a whole team in one device. It feels like pushes and pulls from all sides. The popular 6-axis sensor is a real overachiever. It doesn’t just feel like a shove. It feels like a twist, too.

• It feels stretching and pulling in three directions straight: up/down, left/right and forward/backward.
• Plus, it senses the twists and turns around each of those lines.

It is almost an X-ray insight into the physical forces in action. You read the entire story, not only one chapter.

Go Single-Axis When Your Task is Simple and Straight

Never underestimate a simple tool. For straightforward jobs, a single-axis sensor is often the best pick. It’s tougher, cheaper, and easier to set up.

Choose a single-axis sensor when the force is predictable and moves in one clean line.

You see this in everyday situations:

Basic Push/Pull Tests

Similar to putting a rope to the test and checking its capacity to hold a certain weight.

Weighing Stuff

Monitoring how much material is in a storage bin.

Quality Checks

Making sure a machine part is always pressed together with the same force.

Here’s the takeaway: If your problem is as simple as “Is this force strong enough?” or “How much weight is here?”, then a single-axis sensor is your best friend. It’s the reliable specialist.

Multi-Axis Sensor with Sensor Customization

Time for Multi-Axis When Things Get Complicated

Forces in the real world are messy. They rarely come from just one direction. That’s when you need the bigger picture.

You need a multi-axis sensor when forces get tangled up or when you need to understand a complex motion.

This is where the magic happens:

Advanced Robotics

The robot sanding a curved concept of a piece of wood should have the ability to control the push and the slide in the lateral direction in order to acquire a smooth finish.

Sports Science

In order to study a golf swing, you must record the downward force, the rotational twist, and the side-to-side shear at the same instant.

Tough Product Testing

When you push a new game controller button, you need to know if an awkward push is bending the plastic inside. A single-axis sensor would miss that.

A multi-axis sensor is not an extravagance in such instances. There is no other solution than doing the job right.

Let’s Bring It Home

It is all relative to the problem you are solving.

• Single-Axis is your hero for simple, one-directional tasks. It’s the reliable specialist.
• Multi-Axis is your champion for complex, interactive applications. It’s the master of context.

Remember, the goal isn’t to buy the most advanced sensor. The goal is to buy the sensor that fixes your problem.

Still undecided, just make a call to us. The team at MareX eats, sleeps, and breathes force measurement. We assist your type of people on a daily basis. We can make the noise disappear and get the just-right solution to your project. Don’t waste time guessing.

Designing a Custom Sensor Manufacturing Workflow: From Concept to Calibration

It often starts with a problem. A machine that keeps failing on the production line. A surgery robot that requires a finer hand. A study project that requires a high degree of accuracy, which is not provided by off-the-shelf parts.

But between that initial challenge and a finished product lies a critical, often messy, journey. How do you transform a concept into a precision sensor that works flawlessly in the real world? The secret isn’t just a great design. It’s a rock-solid manufacturing workflow.

This post will walk you through the five essential stages of creating a custom sensor. We will plot the route between your original notion to ultimate calibration. You will know how not to fall into typical traps. And you can watch how a clear process will transform a complex element into a consistent high-performance element.

The Five Non-Negotiable Stages of Sensor Creation

Building a sensor is like conducting a symphony. Every section must come in at the right time. Miss a step, and the entire performance suffers. Here is the framework we use to ensure harmony from start to finish.

Stage 1: The Deep Dive – Uncovering the Real Need

This is the most important phase. It’s where we move from “what you want” to “why you need it.” We don’t just take a spec sheet. We have a conversation.

We ask questions like:

• What is the physical environment? Extreme heat, vibration, and moisture?
• What forces will it actually see? Short bursts? Constant pressure?
• How will it connect to your system? What data output do you expect?

A client once came to us for a “standard torque sensor.” After asking these questions, we discovered their device would experience massive shock loads. A standard sensor would have failed within weeks. We designed a ruggedized version from the ground up. That’s the power of a deep dive. It is time, money, and future-saving.

Stage 2: The Blueprint – Where Ideas Take Shape

Now, we translate those needs into a tangible design. This is an engineering playground. We select the right materials. We model the internal strain gauges. We run simulations on the housing.

We focus on three core pillars:

1. Performance

Will it meet the accuracy and range requirements?

2. Durability

Can it survive its operating life?

3. Integrability

Will it fit and connect without forcing you to redesign your entire assembly?

This stage produces a virtual prototype. It’s a complete digital twin. We can spot potential issues before we ever cut metal.

Sensor Customization for Torque

Stage 3: The Hands-On Build – Prototyping and Proof

A design on a screen is just a theory. We need proof. This is where we build a working prototype. It’s a hands-on, iterative process.

We do not simply construct one and that is all. We build, we test, and we refine. This is due to the fact that a material may not behave as anticipated. In other cases, a real-world experiment indicates a minute resonance that the simulation overlooked. This phase is entirely validative in nature. It is that dirty, mundane business that makes the difference between a good and a great sensor. It is aimed at a prototype that works. It excels.

Stage 4: The Final Check – Rigorous Validation Testing

The prototype works. Great! Now we have to make sure it always works. This stage is about brutal honesty. We put the sensor through its paces in conditions that mimic years of use.

Our tests often include:

1. Cycle Testing

Applying the force a thousand, millions of times.

2.  Environmental Testing

Subjecting it to changes in temperatures and moisture.

3. Cross-Talk Validation

Assuring a push does not produce an artificial signal.

This data is gold. It proves the sensor’s reliability. It gives you the confidence to move forward.

Stage 5: The Master Touch – Precision Calibration

This is the last and most important step. A sensor that is not calibrated may be compared with a ruler that has no marks. It may be straight, but it has no use in measurement.

We don’t just check one point. We map the sensor’s performance across its entire range. We apply known, traceable forces and record the output. This creates a unique calibration certificate for each sensor. This certificate is its passport to accuracy. It links its performance back to international standards. This is what makes your data trustworthy.

Your Next Step Towards Flawless Sensing

A custom sensor is a significant investment. But a disciplined, transparent workflow de-risks the entire process. It turns a complex challenge into a predictable, successful partnership. From the initial deep dive to the final calibration certificate, every stage is built on clear communication and proven engineering principles.

At MareX, this isn’t just our process; it’s our promise. As we are nearing decades of experience, your custom sensor will be made right, and made right, built, calibrated and completed.

Advantages of Force Control Grinding System Automation

With the advancement of lean manufacturing, environmental protection policy requirements, and the needs of the factory’s own development, both manual operation and robots have shown certain limitations and cannot meet the growing demand.

Advantages of Force Control Grinding System Automation

First of all, the method based on manual operation mainly depends on the experience of the workers. People have vision, touch, their own thinking and judgment, and can flexibly handle workpieces of any shape and size difference, which is the great advantage of manual grinding. The more experienced technical workers there are, the higher the efficiency and the better the treatment effect.

However, its disadvantages are also obvious. Manual grinding can only rely on feeling and experience. It is impossible to know how much force you have used, nor can it guarantee the stable output of force, the uniformity of the workpiece surface and the consistency of the effect between workpieces; uncertain labor leads to fluctuations in productivity and output.

From a health perspective, the large amount of diffuse dust, noisy noise and high-frequency vibration of the grinder generated during the grinding process pose a great threat to the health of operators, resulting in a sharp reduction in the number of employees. Compared with manual grinding, the use of can achieve efficient and stable continuous operation according to the edited path, helping enterprises to effectively improve production efficiency, product yield and reduce production costs. In the case of complex and diverse workpiece materials, there are many processes involved in workpiece forming, including sheet metal, stamping, casting, injection molding, CNC, etc. Due to differences in material properties and forming methods, the workpiece will have dimensional tolerances, and there will only be differences in data size.

Since force-controlled grinding usually runs precisely according to a debugged path, the running path is fixed and the error is extremely small, when the surface size of the workpiece is slightly larger or the positioning position is slightly deviated, the grinding effect will fluctuate greatly, or even grinding may not be performed. Or due to excessive pressure and excessive grinding, the yield is low and mass production cannot be achieved.

As an independent control execution system, force control grinding is specially developed for polishing and grinding applications. It has more advantages in helping customers overcome the difficulties of automation upgrades, and helps customers reduce costs and improve efficiency in terms of personnel, equipment and processes:

Through flexible force control, the grinding automation of enterprises can be realized;

Make the surface effect of batch-produced workpieces more uniform and consistent; increase production and reduce subsequent grinding costs;

The programming and teaching of robots become very simple, which can greatly improve the debugging efficiency and reduce the requirements for operators;

Data can be stored and retrieved, so grinding and polishing can also be included in the digital production line system;

Reduce the load requirements of the robot for grinding and polishing, extend the life of the robot and grinder, and reduce equipment costs;

In order to make it easier and more cost-effective for customers to apply automated polishing and finishing solutions, the force-controlled grinding system is also being further developed.

Using collaborative robot end tools, it can adapt to the grasping of various objects without external cables, and the direction can be adjusted to adapt to different objects.

More and more companies are experiencing the benefits of collaborative robots in various automation scenarios. Advantages such as easy installation and debugging, small programming amount, and plug-and-play make collaborative robots suitable for more scenarios.

Under the trend of human-machine collaboration, collaborative robot end-of-line tools have achieved good growth. Last year, nearly 14,000 collaborative robots were installed worldwide, and the annual installation volume of collaborative robots increased by 23% from 2017 to 2018. If collaborative robot sales continue to grow, end-of-line tools will double in a few years, creating unprecedented EOAT market opportunities.

In principle, one robot can only perform one type of work. If you want to perform complex work, you need to constantly change the robot. When this exchange operation is done manually, it not only takes time, but it can also lead to human errors. If you use a collaborative robot end tool, the robot can automatically change the manipulator by itself. In addition, even if it is changed manually, the operation becomes very simple and quick.

Even on robots that do not require replacement of the gripper, tool, or end effector, etc., using a gripper quick changer can simplify maintenance or fine-tuning. In addition, for laboratory robots in R&D departments or schools, simply replacing the gripper allows the robot to be shared, making it convenient to carry out various experiments.

In some cases, manufacturers use collaborative robot end-of-line tools mainly because of repetitive and boring work and the lack of suitable workers. In addition, manufacturers want to find ways to improve efficiency, even if the run time is reduced by a few seconds, it can bring more product output. Buying more robots and grippers can create huge benefits.

With the rapid development of industrial automation, the performance of six-axis force sensors, as core components in robotics technology, directly affects the robot’s operating accuracy, safety, and flexibility. This article aims to deeply explore the performance evaluation indicators and selection guidelines of six-axis force sensors for industrial robots, to help engineers and R&D personnel better understand and select sensors suitable for their application scenarios.

1. Overview of Six-Axis Force Sensor

A six-axis force sensor, also known as a six-dimensional force sensor, is a precision measuring device that can simultaneously measure the force and torque of an object in three directions. It is based on the interaction principle of force and torque in mechanics, and converts mechanical information into electrical signals for output through the tiny deformation of elastic elements (such as elastomers or elastic diaphragms). This sensor is widely used in robotics, aerospace, automobile manufacturing, biomechanics and other fields.

2. Performance Evaluation Indicators

1. Accuracy and sensitivity
Accuracy and sensitivity are important indicators for evaluating the performance of six-axis force sensors. Accuracy refers to the degree of deviation between the sensor’s measured value and the actual value, while sensitivity reflects the sensor’s ability to respond to small changes. For industrial robots, high-precision six-axis force sensors can ensure the accuracy and stability of robot operations.

2. Range and overload capacity
The range refers to the maximum load force (or torque) that the sensor can effectively measure. When selecting a sensor, make sure its range can meet the actual working requirements of the robot. In addition, overload capacity is also a factor that cannot be ignored. It refers to the ability of the sensor to maintain a certain measurement capability when exceeding its range. Good overload capacity can protect the sensor from accidental damage.

3. Linearity and hysteresis
Linearity describes the degree of linear relationship between sensor output and input, while hysteresis reflects the inconsistency of sensor output values ​​during loading and unloading. For industrial robots, six-axis force sensors with low linearity and low hysteresis can provide more accurate measurement results and reduce error accumulation.

4. Resolution and Noise
Resolution refers to the amount of small signal changes that a sensor can distinguish. A high-resolution sensor can capture more subtle mechanical changes and improve measurement accuracy. At the same time, the noise level is also an important factor affecting sensor performance. A low-noise sensor can provide a clearer signal output.

5. Environmental adaptability
The working environment of industrial robots is complex and changeable, so the six-axis force sensor needs to have good environmental adaptability. This includes temperature stability, waterproof and dustproof capabilities (such as IP rating) and electromagnetic compatibility. Good environmental adaptability can ensure that the sensor can maintain stable measurement performance under different working conditions.

3. Selection Guide

1. Clarify application scenario requirements
Before choosing a six-axis force sensor, you first need to clarify the specific requirements of the application scenario, including measurement accuracy, range, frequency response, etc. Select the appropriate sensor model and specifications according to the requirements.

2. Investigate sensor brands and manufacturers
There are many six-axis force sensor brands and manufacturers on the market, and their product quality and performance vary greatly. Therefore, when choosing, you need to examine the manufacturer’s technical strength, product quality, after-sales service and other factors, and choose a reputable and powerful brand.

3. Evaluate the cost-effectiveness
Under the premise of meeting application requirements, the cost-effectiveness between the price and performance of the sensor needs to be comprehensively considered. We should not blindly pursue high prices or high performance while ignoring actual needs and economic costs.

4. Field testing and verification
Before finalizing the sensor model, it is recommended to conduct field testing and verification. The sensor is tested for performance by simulating actual working scenarios to evaluate whether its performance in actual applications meets expectations.

IV. Conclusion

As an important component of industrial robots, the performance of six-axis force sensors directly affects the operation and safety of robots. Through the introduction of this article, we hope to help engineers and R&D personnel better understand and select six-axis force sensors suitable for their application scenarios. In the selection process, it is necessary to comprehensively consider multiple factors such as accuracy, range, linearity, hysteresis, resolution, noise, and environmental adaptability, and conduct a comprehensive evaluation based on actual needs and economic costs. Finally, a six-axis force sensor with high cost performance and stable performance is selected to provide strong guarantee for the precise operation and efficient operation of industrial robots.
