Imagine a robot performing delicate 3D inspections or laser cutting with pinpoint accuracy. But with fluctuating plant temperatures, robot self-heating, and occasional mishaps, even top-tier industrial robots struggle to maintain precise performance over time.

Enter DynaFlex™ by Dynalog—an advanced, automated calibration system designed to take robotic accuracy and repeatability to a new level. Here’s how it transforms robotic reliability, even in the most demanding environments.

What Makes the DynaFlex™ System Essential?

The Challenge of Precision

Many tasks require highly accurate robot positioning, from inspection and precision drilling to waterjet cutting. But even the best industrial robots are not accurate to begin with and can also be thrown off by ambient temperature changes, robot self-heating, mechanical wear, and other unpredictable factors. With DynaFlex™, these common issues are tackled head-on, ensuring each robot can keep up with accuracy and repeatability over time—no matter the production environment.

How DynaFlex™ Does It

DynaFlex™ isn’t just a one-time calibration tool. It’s a continuous, automated system that fine-tunes your robot at every step. Here’s how it works:

1. Smart Calibration Process: Using precise sensors, such as 3D cameras and lasers, DynaFlex™ measures calibration targets (placed around the robot) to provide the initial high Absolute Accuracy and performs measurements of the calibration targets periodically to adjust the robot’s key parameters—from its structure to the end-effectors (tools) it carries. This ensures that every robot movement aligns with the intended position, even compensating for minor structural shifts due to ambient temperature changes and robot self-heating.
2. Advanced Filtering: DynaFlex™ applies a “filter” to correct each robotic position rather than directly modifying a robot’s internal settings. This approach allows the system to adapt to various robots without altering their original control settings, which means it can seamlessly work across different robotic brands and types. The filter calculates exactly where the robot must be, compensating for deviations from the ideal.
3. Real-Time Temperature Compensation: Temperature fluctuations and robot self-heating can lead to slight changes in a robot’s structure, resulting in a loss of precision. DynaFlex™ dynamically adjusts to these changes, reducing drift to within a remarkable 0.1 mm—far better than the typical 0.5 mm drift without such compensation.

The Benefits of DynaFlex™: Why It’s a Game-Changer

• Top-Tier Precision: By refining the positioning of the robot’s tools and fixtures, DynaFlex™ ensures that each movement is as close to perfect as possible. This high precision is vital for industries that rely on exact robotic placement, from automotive manufacturing to aerospace.
• Adaptability: DynaFlex™ is designed to handle the rigors of real-world environments, adjusting for site conditions, payloads, and even different robotic setups. This flexibility makes it an asset across various high-precision industries.
• User-Friendly Automation: With its automated recalibration, DynaFlex™ is straightforward to use, even during production. The system handles recalibrations as needed, performed during part transfer, allowing operations to continue with minimal interruption.

Real-World Applications: Where DynaFlex™ Shines

For applications like robotic inspection where features measured by the robotic measurement system are compared to CMM measurements of the same features, DynaFlex can provide the initial high robot Absolute Accuracy and then maintain the accuracy overtime by compensating for the robot drift due to ambient temperature variation/robot self-heating.
