Center of Gravity Testing in Robotics Demands Precision Load Cells

/0 Comments/in , /by

As the use of robotics expands across industries and the types of robotic motions grow in complexity, advanced testing using quality measurement solutions is essential. Contact momentum and gross measurements of indicators are not enough for sophisticated robotics. With the requirements for robots and cobots to have fluid and inertial movement capabilities, control and feedback demand maximized feedback and resolution.

Related to the testing of inertia, load shifting, and interaction, is defining the center of gravity for robots’ actions and applications. The center of gravity (CoG) of a robotic system is a critical factor in its stability and performance.

The CoG is the point at which the entire weight of the system is evenly distributed. If the CoG is not properly located, the system may be unstable and prone to tipping over, which could damage the robot.

For any robotic application that deploys advanced mobility features, the center of gravity can affect the way the system moves. It can also impact the exactness of its movements. Thus, it is essential to use measurement solutions that are highly precise. See: Advancements in Robotics and Cobots Using Interface Sensors.

Why Robotic Engineers Care About CoG Testing

  • Stability: The CoG is a major factor in determining the stability of a robot. If the CoG is not properly located, the robot may be unstable and prone to tipping over. This can be a safety hazard, and it can also damage the robot. It is an expensive mistake to not have stability proven before moving forward with the design.
  • Performance: The CoG can also affect the performance of a robot. If the CoG is located too high, the robot may be less maneuverable. If the CoG is located too low, the robot may be less stable. By optimizing the CoG, robotic engineers can improve the performance of the robot and use for actions that rely on exact movement.
  • Safety: In some industries, such as manufacturing, medical and aerospace, there are safety regulations that require robots to have a certain CoG. For example, in the automotive industry, robots that are used to weld cars must have a CoG that is below a certain point. By testing the CoG of their robots, robotic engineers can ensure that they are meeting safety regulations.

There are different methods for determining the CoG of a robotic system. One common method is to use strain gage load cells. Not all load cells are designed for precision measurement. Interface specializes in precision. Center of gravity testing demands strict measurement. For example, Interface compression load cells are often used in center of gravity testing for robotics because they are very accurate and can measure remarkably small forces.

Interface load cells measure force, and they can be used to determine the weight of a system at different points. By measuring the weight of a system at different points, it is possible to calculate the location of the CoG.

Interface load cells used for center of gravity testing are typically in our miniature load cell line, due to the size of the installation and testing environment. Miniature load cells are easily embedded into robotics, as well as can be used for continuous monitoring.

Surgical Robotic Haptic Force and CoG

Robots used for surgery often utilize haptic force feedback for ensuring that the surgeon does not apply too much force, creating harm or greater impact on the patient. Haptic is the use of force, vibration, or other tactile stimuli to create the sensation of touch. In the context of invasive surgery, haptic force feedback from robotics is used to provide the surgeon with feedback about the forces they are applying to the patient’s tissue. CoG testing can help to prevent the robotic arm from tipping over during surgery.

CoG testing is important for haptic force feedback in invasive surgery because it ensures that the robotic arm is stable and does not tip over during surgery. The CoG is the point at which the entire weight of the robotic arm is evenly distributed. If the CoG is not properly located, the robotic arm may be unstable and prone to tipping over. This can be a safety hazard for the surgeon and the patient.

CoG testing is also used to optimize the design of the robotic arm for haptic force feedback. CoG testing using precision load cells can verify the performance of the robotic arm in haptic force feedback applications. After the robotic arm has been designed and optimized, CoG can ensure that the robotic arm is able to provide the surgeon with the feedback they need to perform surgery safely and accurately.

Robotic Center of Gravity on Production Line

A company is developing a new robotic arm that will be used to simulate human behavior on a manufacturing product line. The robotic arm will be used to pick and place products, and it is important that the arm is stable and does not tip over. To ensure the stability of the robotic arm, the company needs to determine the CoG of the arm. The load cell is placed on the arm, and the arm will be moved through a range of motions. The data from the load cell will be used to calculate the CoG of the arm.

CoG Testing and Multi-Axis Sensors

Multi-axis load cells are growing in use for robotics testing to provide data across 2, 3 or 6 axes at any given time. These high functioning sensors are ideal for robotic tests where there are simulations of human behaviors. This is detailed in Using Multi-Axis Sensors to Bring Robotics to Life.

To perform CoG testing using precision load cells, a robotic system can be placed on a platform that is supported by the load cells. We call these force plates. The load cells measure the weight of the system at different points, and the data is then used to calculate the location of the CoG. Visit our 6-Axis Force Plate Robotic Arm application note to learn more about force plates and multi-axis sensors.


Benefits Of Using Precision Load Cells for CoG Testing:

  • Interface precision load cells provide advanced sensors functional beyond contact and simple indicator measurement, to maximize robotic feedback and optimize performance.
  • Interface precision load cells can provide accurate measurements of the weight of a robotic system at different points.
  • Interface precision load cells are repeatable and dependable, which means that the results of CoG testing are consistent when testing robots and cobots.
  • Interface precision load cells are easy to use, which makes them a practical option for CoG testing and integration into the actual robot.

There are several benefits to using an Interface Mini Load Cells, like our ConvexBT Load Button Load Cell or MBI Overload Protected Miniature Beam Load Cell for high accuracy CoG testing.

First, the miniature load cell is small and lightweight, which makes it easy to attach to the robotic arm. Second, the load cell is designed for precision measurement, which ensures that the CoG of the arm is accurately determined. Third, the quality of Interface precision load cells provides repeatable and dependable measurement, which means that the results of CoG testing are consistent.

Using a miniature load cell of high accuracy is a valuable way to test the CoG of a robot used to simulate human behavior on a product line. This ensures that the robot is stable and does not tip over, which is critical for safety and efficiency.

In addition to testing the CoG of a robotic arm, other tests for these types of robotics include the weight of the arm, the distribution of the weight of the arm, and the friction between the arm and the surface it is moving on. By considering these factors, it is possible to accurately determine the CoG of a robotic arm and ensure that it is stable and safe to operate.

There are many factors that can affect the accuracy of CoG testing using load cells, including the design, capacity and range of measurement of the load cells, the stability of the platform, and the distribution of the weight of the system.

CoG testing is an important part of the design and development of robotic systems. By determining the CoG of a system, it is possible to improve its stability and performance. If you are interested in learning more about CoG testing using Interface precision load cells, please contact us.

Interface Supports Wind Tunnel Testing

/0 Comments/in , /by

In the development of an airborne vehicle, like a plane or helicopter, wind tunnel systems are used to gather data across a variety of tests related to the aerodynamics of the vehicle’s design. Whether an object is stationary or mobile, wind tunnels provide insight into the effects of air as it moves over or around the test model. Interface is a supplier of measurement solutions used for aircraft and wind tunnel testing.

Wind tunnels are chambers that test small scale model versions of full systems, or in some cases, parts and components, depending on the size and capabilities of the wind tunnel. They work by allowing the engineers to control airflow within the tunnel and simulate the types of wind force that airplanes and other aircraft will experience in flight. Wind tunnels are also used for testing automobiles, bicycles, drones and space vehicles.

By taking careful measurements of the forces on the model, the engineer can predict the forces on the full-scale aircraft. And by using special diagnostic techniques, the engineer can better understand and improve the performance of the aircraft.

The process for measuring the force and how it reacts to this force works by mounting the model in the wind tunnel on a force balance or test stand. The output is a signal that is related to the forces and moments on the model. Balances can be used to measure both the lift and drag forces. The balance must be calibrated against a known value of the force before, and sometimes during, the test.

Interface’s strain gage load cells are commonly used in wind tunnel testing due to their quality, accuracy and reliability. The instrumentation requirements often depend on the application and type of test. The range of options for both load cells and instrumentation vary based on scale, use, cycle counts, and data requirements.

Instrumentation used in wind tunnel testing can be as simple as our 9325 Portable Sensor Display to a multi-channel data acquisition system. Interface analog, digital and wireless instrumentation solutions provide a range of possibilities. As is the case, wind tunnel testing is typically very sensitive. It is important to calibrate the instrumentation before each test to measurement accuracy.

Types of Wind Tunnel Tests Using Force Measurement Solutions

  • Lift and drag: Load cells are used to measure the two most significant forces that impact aircraft design. Lift is the force that acts perpendicular to the direction of airflow and keeps the craft airborne. Drag is the force that acts parallel to the direction of airflow and opposes forward motion.
  • Side force: This force acts perpendicular to both the direction of airflow and the lift force. It is caused by the difference in pressure between the upper and lower surfaces of the aircraft.
  • Moments: Moments are the forces that act around a point. The most common moments measured in wind tunnels are the pitching moment, the yawing moment, and the rolling moment.
  • Stability and control: Tests conducted to measure the stability and controllability of an aircraft are commonly using force measurement solutions for aircraft design changes or integrating new parts into an existing model.
  • Performance: Particularly important with new designs, engineers use these tests to measure the simulated flight performance under maximum speed, range and fuel efficiency.

The specific tests that are conducted in a wind tunnel depend on the project requirements.

Multi-Axis Sensors for Wind Tunnel Testing Applications

In measuring the forces of a wind tunnel test, multi-axis sensors offer the perfect solution for collecting as much data as possible across every axis, giving the engineer a more complete picture on the aerodynamics of the plane. In fact, Interface has supplied multi-axis load cells for use in several wind tunnel testing applications, for OEMs, testing facilities and part makers.

We offer a variety of multi-axis options including 2, 3 and 6-axis standard and high-capacity configurations depending on testing and data requirements of the user. These sensors can precisely measure the applied force from one direction with little or no crosstalk from the force or moment. Interface products provide excellent performance and accuracy in force and torque measurement.

To match the demands of the volumes of data available using multi-axis sensors in wind tunnel testing, Interface often provides several data acquisition instrumentation solution along with our BlueDAQ software.

Wind Tunnel Test Application

A major aerospace company was developing a new airplane and needed to test their scaled model for aerodynamics in a wind tunnel, by measuring loads created by lift and drag. Interface Model 6A154 6-Axis Load Cell was mounted in the floor of the wind tunnel and connected to the scaled model by a stalk. The wind tunnel blew air over the scaled model creating lift and drag, which was measured and compared to the theoretical airplane models. The output of the 6-axis sensor was connected to the BX8-AS Interface BlueDAQ Series Data Acquisition System, which was connected via USB cable to a computer. Using this solution, the company was able to analyze the collected data and made the necessary adjustments in their design to improve the aerodynamics of their theoretical airplane models.

Interface supports wind tunnel testing and all uses of force measurement in the advancements in aeropspace.

Wind tunnel testing is critical to the aircraft industry, as well as other industries like automotive and space. Interface has been providing multi-axis sensors and strain gage load cells to industry leaders and wind tunnel operators. We understand the unique needs of this type of testing and the instrumentation options that work best with our high-accuracy sensors. We also can work to provide custom solutions, load cells for use in extreme environmental conditions. Contact us to get the right solution for your specific testing program.

Mounting Tips for Multi-Axis Sensors

/0 Comments/in /by

Understanding best practices for mounting is critical to collecting accurate data, especially when it comes to multi-axis load cell solutions. As more testing engineers choose multi-axis sensors for the benefits of additional data, it is important to note that  improper mounting can cause multiple axis to be unaligned and skew the data across the various axis you are measuring.

In follow-up to our webinar, Inventive Multi-Axis and Instrumentation Webinar, here are some valuable reminders on how to properly mount both 3-Axis and 6-Axis load cells to gather the most accurate and reliable data for any test and measurement application.

The first thing to understand is there are certain mounting considerations that are important across every type of multi-axis sensors. These considerations begin with understanding the relationship between the sensor and mounting hardware. The sensor is made up of the electronic internals of a load cell, while the mounting hardware is comprised of plating that needs to align with the test system.

The next thing to understand is that deflections in the system introduce errors and apparent crosstalk. To avoid deflections, plates and fixtures used in mounting must be stiff enough to avoid deflections. The best way to understand this is to try and emulate how stiff the plating was when the sensor was calibrated, this will help you understand how stiff you need the plate to be in the testing application.

Finally, every single multi-axis sensor model also comes with unique mounting instructions, so be sure to consult the written instructions if you have questions. When it comes to mounting instructions for our products, Interface publishes all mounting instructions online.

Mounting instructions provide information on the class of hardware for mounting, as well as important data such as the torque on the dowel pins, for cases that include dowel pins.

For 3-axis mounting, we provide assembly instructions for each type of load cell available. For example, the assembly instructions pictured on the far left shows a 3-Axis sensor with four threaded mounting holes on the top surface and two dowels that should be used to avoid the plate slipping. The dowel pins are crucial to aligning the axis. The instructions also show mating services which are identified with arrows or hash marks.

The 6-axis mounting hardware is a bit different in that there are more holes in the mounting plates and fixtures for dowel pins, which stop the mounting plate from deforming or bending because this can cause inaccuracies in data. Additional mounting locations are necessary to securing the plates and fixtures.

Considerations for 6-axis mounting include the potential need to use a double-plate mounting arrangement, the plates must be suitably thick, the plates must have the same material as sensor for thermal matching, and flat and smooth mounting plate surfaces are preferred. The example here shows some of the features mentioned above.

We hope this simple guide will provide you with the information you need to get the most out of your multi-axis sensors. If you are ever unsure about any details within the mounting process for multi-axis sensors, feel free to contact Interface for support or questions about any multi-axis products.

Force Sensing Keeps Factories Running Feature in Fierce Electronics

/0 Comments/in , /by

In the recent article, ‘May the force be with you: Force sensing keeps factories running, product quality high’ Dan O’Shea at Fierce Electronics writes about the growing demand for sensors in industrial automation applications.

Following his interview with Interface’s Keith Skidmore, Dan writes:

‘While some sensors are more focused on monitoring equipment or measuring environmental conditions around a manufacturing process, force sensors measure mechanical forces occurring in the equipment and processes, and the products being manufactured. They measure things like load, tension, resistance, weight or total pressure applied. By employing this kind of sensing technology, manufacturers can monitor the health of their equipment and improve quality assurance for their products.’

“Testing things by applying a force to them is super common. Many products in lots of industries get tested this way, from aerospace to automotive, through to consumer goods. Chairs, furniture, mattresses, ladders–basically, anything that’s being manufactured, there can be a desire to figure out how strong the various parts of those products are.” Keith Skidmore, engineer and regional sales director at Interface

As we look ahead to 2022, we are also investing in new and existing trends and exploring how they will shape the overall market next year and beyond. To help prepare our customers, here are our predictions for the new year, along with what is hot and trending in force measurement. The following provides some insights from our experts on how Interface is prepared to address these trends, while continuing to serve our customers at the highest level of satisfaction. Here is Interface’s viewpoint on market trends and predictions for 2022 and beyond.

Big Data Continues to Rule Product Design and Test

Over the last few years, we’ve shared our view on the Industry 4.0 revolution and how Interface customers are demanding more data from their T&M tools to give exactness in accuracy and all-encompassing performance data at the earliest phases of product design. Not only will this continue, but it will expand rapidly. In the force measurement world, Interface has responded by serving our customers with new innovations in multi-axis sensors that provide more force data on more axis. Interface offers a wide variety of multi-axis sensors including 2, 3 and 6-axis sensors.
