Accuracy and Repeatability Dependency from Speed about MELFA Robots

This paper presents an experimental investigation of the accuracy and repeatability dependency on speed for MELFA robots. The study was conducted using a MELFA RV-2F robot arm equipped with a high-precision displacement sensor to measure the end-effector position. The robot arm was programmed to perform a series of point-to-point movements at different speeds, and the position error and repeatability were measured and analyzed. The results indicate that the accuracy and repeatability of the MELFA robot are strongly dependent on the speed of the robot arm. At low speeds, the robot arm exhibits high accuracy and repeatability, while at high speeds, the accuracy and repeatability decrease significantly. These findings have important implications for the design and operation of MELFA robots and can be used to optimize their performance in various industrial applications.
