Data Acquisition Systems Supporting Robotics Development and Manufacturing
In recent years, robotics technology has advanced rapidly with the development of intelligent manufacturing, artificial intelligence, and sensing technologies. Robots are no longer limited to industrial workshops or research laboratories; they are increasingly appearing in large-scale demonstrations where dozens or even hundreds of robots move in perfect synchronization to perform complex and coordinated motions. These impressive displays reflect the remarkable progress in motion control, sensing systems, and mechanical design.
Today, robotics technology has expanded into a wide range of applications, including industrial robots, service robots, and household robots. However, the realization of these technologies does not happen overnight. Behind every reliable robotic system are thousands of hours of testing, measurement, and validation. For robotics development and manufacturing, simulation provides the theoretical foundation, while real-world environmental feedback, electrical characteristics, and structural fatigue must ultimately be verified through high-precision data acquisition systems.
Research and Development Testing
During the research and development phase, extensive fatigue tests and load impact tests are typically conducted. Strain gauges are often attached to structural components such as aluminum alloy or carbon-fiber robot arms and rotating shafts. A data acquisition system records stress variations in real time when the robot performs high-speed movements, sudden stops, or impact events.
These measurements are used to validate the accuracy of finite element analysis (FEA) models and determine whether structural components present any risk of fatigue failure.
In addition, key components such as motor windings, gear reducers, driver boards, and battery packs generate significant heat during long-term operation. Temperature monitoring using data acquisition equipment provides important data for optimizing thermal management strategies and defining safe temperature protection thresholds.
Production Line Testing and Calibration
A robot’s ability to perceive environmental changes and respond accordingly relies on various sensors integrated into the system, such as torque sensors, laser rangefinders, and displacement sensors. The analog signals generated by these sensors must be continuously collected, recorded, and analyzed through data acquisition equipment, and compared with reference values for calibration and verification.During the final stages of assembly line testing, data acquisition systems monitor the motor current waveform when the robot performs standard motion trajectories. If abnormal ripple or an unusually high RMS value appears in the current waveform, it may indicate mechanical assembly issues, such as poor reducer break-in, bearing damage, or uneven lubrication.
In the burn-in testing stage before shipment, data acquisition systems simultaneously record current, voltage, and temperature at critical locations. Only products whose operating data remain within the designed performance envelope throughout the entire test period are approved for delivery.
Data Acquisition as the Link Between Machines and Physical Reality
From impressive robotic performances to laboratory testing and production line verification, data acquisition systems may not be visible on stage, but they serve as a critical bridge between robotic systems and the physical world. By capturing accurate electrical, thermal, and mechanical signals, these systems provide engineers with the data needed to evaluate performance, diagnose issues, and continuously improve robotic technologies.
With the rapid growth of robotics innovation, reliable data acquisition solutions have become an essential component of both research and manufacturing processes. Companies such as Xi'an Ketu Test Technology Co., Ltd. (KETU&TEST) provide multi-channel data acquisition equipment including the KTVS-32A voltage sample device, temperature scanning modules, and strain and current measurement systems. With high precision and stable performance, these solutions offer a dependable testing foundation for robotics development and production.
Every signal accurately captured contributes valuable insight for engineers and supports the continuous evolution of robotics technology.
