Adaptive Control
Metris has taken part in a major Airbus research project that results in greater level of automated drilling and riveting within the aerospace giant. Since industrial robots do not meet Airbus process specifications, Airbus, Metris, KUKA and Delmia partnered to develop a new aerospace grade robotic platform. This patent-applied-for solution establishes a dynamic on-line link between a KUKA robot and a Metris K-series Optical CMM based metrology solution. This will result in a robotic platform that features adaptive real time motion control. Airbus expects that the flexible and low cost robotic solution - operating on aerospace accuracy tolerance - will reduce cost, cut production time and improve quality once being deployed.
The unique and fully integrated metrology system from Metris measures the virtual world first and adapts the real world to fit. This intuitive system is called Adaptive Robot Control, as it makes the robot intelligent enough to make its own adaptations. This means that the robot can accurately compensate for robot deformation (under dynamic load), temperature fluctuations and mechanical play, for example. The metrology system makes the robot aware of deflections by measuring the relative positions of the target and the robot as it
moves towards it. The robot is able to coordinate that data on-line and make the necessary compensations instantaneously.
