Interface Mini Load Cells Growing in Product Use and Testing

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.

Are Load Cells Used in Vacuum Environments?

/0 Comments/in /by

Vacuum testing labs are essential for ensuring that products and materials are safe and dependable in vacuum environments. A vacuum environment is an area where there is little or no matter. This means that there are very few gas molecules present, and the pressure is incredibly low. Vacuum environments are often created using vacuum pumps, which remove gas molecules from an enclosed space.

Vacuum environments are used to simulate the conditions that products and materials will experience in space or other high-altitude environments. These types of testing labs typically have a vacuum chamber that can be evacuated to an incredibly low pressure. The vacuum chamber is then used to evaluate products and materials for a variety of properties. Engineers use vacuum environments in testing for reduced contamination, improving heat transfer, and to reduce the weight of products.

Tests performed in vacuum labs are used to determine the rate at which gases are released from a product or material and the ability of a product or material to withstand a vacuum without leaking. Thermal cycling tests are done to assess the ability of a product or material to withstand changes in temperature in a vacuum environment. Other tests are done to understand how the test article withstands exposure to radiation.

Vacuum testing labs are used by a variety of industries, including aerospace, medical, and defense. These labs are common for material process testing and used in R&D. Vacuum testing helps to identify potential problems with products and materials before they are used in a real vacuum environment. Engineers use this type of testing to improve the performance of products and materials and ensure they meet the required standards. Contact Interfaced to explore your options.

Can load cells be used in a vacuum environment?

Load cells can be used in a vacuum environment. However, not all load cells are created equal or suited for this specialized use case. Some load cells are designed that make them appropriate for vacuum environments, while others are not. Load cells that are not engineered to perform in vacuum environments may not be able to withstand the low pressures and outgassing that can occur in a vacuum. Using quality load cells that are manufactured by force measurement experts in sensor technologies is important in any consideration. It is critical to review the specifications and requirements with a qualified applications engineer.

Key considerations when choosing a load cell for a vacuum environment:

  • Outgassing: Load cells that are used in vacuum environments will have low outgassing rates. This means that they will not release gases into the vacuum chamber, which can contaminate the environment and interfere with measurements.
  • Mechanical strength: Load cells must be able to withstand the low pressures that can occur in a vacuum. They will also be able to withstand the conditions that can be generated by vacuum processes, such as outgassing and condensation. Form factor and model material of the load cell are important in choosing a load cell for this use case.
  • Temperature range: Load cells will need to operate in a wide range of temperatures. This is important because vacuum chambers can be very cold, especially when they are first evacuated, or when they are used to simulate high altitudes or space.

If you are looking for a load cell that can be used in a vacuum environment, please review with Interface application engineers to determine if the model fits your test requirements. We also can offer custom solutions to ensure that the load cell maintains the accuracy and performance specifications based on your exact test plan.

Can a load cell be vented for use in a vacuum testing lab?

Technically yes, you can vent a load cell to be used in vacuum. This allows the internal cavity of the load cell to equalize with external vacuum. However, this does not prevent outgassing and can cause the gages and wiring to be subject to humidity and condensation.

Cabling is extremely important when using any sensor in this environment. There are options to make the load cells wireless using Bluetooth technology.

Caution: Interface recommends that all our products used in this type of environment are designed, built, and calibrated for use in this environment. Venting an existing load cell can alter the performance and damage the cell.  By designing the load cell with venting for use, we can ensure that it will meet the vacuum test range.

Interface also can install thermocouples to work with the sensor to detect temperature in this type of testing environment. In fact, our engineers have designed load cells to package the thermocouples inside the form factor for convenience and performance benefits.

Interface engineers have worked with testing labs for decades. We are available to assist with any use case requirements to determine the best measurement solution.

Interface Solutions for Lifting Applications

/0 Comments/in /by

Lifting is the action of raising an object to a higher level or moving an object to a different position. Tension load cells accurately measure forms of lifting, as they measure pulling by design. Choosing the right sensor for this type of measurement requires consideration of the size of object that is lifted, and mechanism used in the act to create the lift. Read more in our latest case study Cranes and Lifting.

Often large capacity load cells are used in industrial equipment, cranes, forklifts, rigging, and even aircraft testing equipment to measure forces applied in heavy lifting and for load monitoring, as well as to maintain accuracy in movement. Larger capacity load cells can range from 10,000 to million lbf, or even larger. Rugged load cells are frequently selected for this type of equipment to sustain harsh environmental conditions for both testing and during real-time use.

Smaller capacity load cells, such as s-types and miniature beams, measure the lift action in machines, medical equipment, packaging, robotics, drones and moving equipment. In all circumstances, force measurement sensors help product engineers and manufacturers improve safety and the quality of products they build. They are versatile and easily integrated into machines and components.

Beyond the measurement specifications, other top feature considerations when selecting the right sensor include weight of the sensor, requirements for overload protection, enclosures and ruggedized material used to construct the device, signal outputs for data, cabling, or wireless functionality, mounting or clamping, and instrumentation for data acquisition.

For measurement in lifting applications, Interface products provide the industry’s most accurate and reliable data available through force measurement sensors. Products we provide for lifting include multi-axis sensors, load washer load cells, low profiles, miniature load cells, load shackles, load pins, tensions links, instrumentation, and torque transducers.

The following are examples of products we supply for lifting equipment and use cases.

A manufacturer aerial lifts wants to test its self-propelled boom platform to ensure it can operate at heavy capacities when in use, and at different angles. This testing is vital for safety and protecting operators as well as those at the site of where equipment is in use. The sensors help to prevent any accidents in case of a lifting overload. The Interface application engineers recommends the multi-axis 3AXX 3-Axis Force Load Cell model 3A160 to capture the required data for monitoring in real-time. Paired with the 920i Programmable Weight Indicator and Controller, the operator had accurate information when using the equipment.

AIRCRAFT LIFTING TEST RIG

 

An aerospace manufacturer is looking to accurately measure the valves in their aircraft lifting test equipment. Interface’s solution is to install a 1200 High Capacity Standard Precision LowProfile™ Load Cell in between the aircraft testing rig and the lifting jack. The load cell will measure the load’s force safety valve when the lifting equipment opens. Results will be sent to the 9890 Strain Gage, Load Cell, & mV/V Indicator, where the customer can see it displayed in real-time. 

LIFTING HEAVY OBJECTS


In this common use case, a customer needs to measure the load when using a crane to move heavy construction materials around the work site. This includes monitoring the weight of these objects as they are lifted in the air. It was critical that the device offer high accuracy readings and also work within the equipment already in place. Key is the instrumentation capabilities to provide wireless outputs. Interface recommends using our WTSSHK-B Wireless Load Shackle connected in crane load string to measure forces. Model WTS-BS-1-HA Battery Powered Handheld Display is used to wirelessly receive load information and display results.
