Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning DailyNews Daily News – Investigators publish new report on Robotics. According to news reporting originatingfrom Xiamen, People’s Republic of China, by NewsRx correspondents, research stated, “A new calibrationdevice using a double-ball rotary structure and three contact displacement sensors is proposed to measurethe spatial errors of six-axis serial robot. The error model is divided into kinematics part and static stiffnesspart, established by Modified DH (MDH) model and virtual joint method.”
