  Robot Cell Calibration System

Robot Cell Calibration System

The well-established DynaCal system now also comes in a “smaller package”: the DynaCal-Lite system. It uses the same proven proprietary measurement hardware, but with a subset of software capabilities – offering a simpler interface targeted towards those more basic robot accuracy applications.
 

DynaCal-Lite vs. (regular) DynaCal


 

The problem addressed by the DynaCal-Lite system remains the same: how to improve to overall positional accuracy of a production robotic cell. But whereas the regular DynaCal system offers a variety of tools and functions to dramatically improve the accuracy of the robot and its peripherals, the DynaCal-Lite system  is designed to operate exclusively and seamlessly with the functions and tools available right on the robot controller. In particular, the otherwise powerful “Filter” compensation function is not available with the DynaCal-Lite version; similarly several robot parameters (e.g. link lengths, etc.) are not calibrated.
 
Surely, this means that the DynaCal-Lite system cannot deliver the same level  of accuracy as the DynaCal system. But on the other end, it will make your robot cell as accurate as possible, without requiring the use of an external PC  for any advanced compensation. In certain applications, there is indeed no need for the highest possible accuracy – as the regular DynaCal system delivers – but you still require some minimum or “base” robot-cell accuracy: robot’s joint axes need to be properly mastered, the TCP-Frame should be defined as precisely as possible, and a well-defined USER-Frame is often also required.
 
That’s what the DynaCal-Lite system is for – quickly and precisely!
 
In fact, the DynaCal-Lite system provides a solution not only for basic initial calibration, but also for recovery purposes – in case of a robot crash or in case of an end-effector replacement, for example. By using the optional “Maintenance Module”, your robot-cell will recover within the robot’s level of repeatability, thus eliminating “manual touchups” of robot programs altogether! The DynaCal-Lite system can also be used as a simple “Quick Check”, allowing you to verify the proper operation of your robotic cells in a matter of minutes. And there are more features available, as listed on the back page.
 

The Keys to DynaCal’s Success...


 

The DynaCal-Lite logically maintains some of the key features of the regular DynaCal system, specifically in terms of ease-of-use and versatility. The DynaCal-Lite solution requires the use of a stand-alone PC, but only for mea- surement purposes, with an intuitive “drag-and-drop” type interface. The propri- etary DynaCal hardware (connected directly to the PC) provides outstanding measurement accuracy within a rugged and compact package. In fact, the com- plete DynaCal-Lite system - with all necessary mounting accessories - comes within an easily transportable case no larger than a briefcase! And of course,  the DynaCal-Lite system works with virtually any brand of industrial Robot.
