Calibration of industrial robots with pneumatic gravity compensators [PDF]
2017 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2017 The paper is devoted to the stiffness modeling of heavy industrial robots with pneumatic gravity compensators. The main attention is paid to the identification of elastostatic parameters and calibration accuracy. To identify the desired set of parameters two-step identification procedure is developed. To reduce impact of the measurement errors, the set
