Investigation of the performance capabilities of kinematic measurement systems

Objectives

  • Assessment of the performance, including the temporal component
  • Development of common criteria for the different instruments (manufacturer)
  • Inclusion of the GUM (Guide to the expression of Uncertainty in Measurement) for the kinematic range
  • Optimisation with regard to the scope of application

 

Status of Work

For the determination of a movement known as the fourth parameter of the trajectory, time plays a major role. Therefore, in the overall robotic tachymeter system, it is necessary to investigate the synchronisation and sensors of the individual subsystems more accurately. With a developed 4-D calibration system, time delays of the individual parameters can be determined.

 

Future Work

The determined time delays for the discrete positions of the time-referenced rotating arm must be analysed while the corresponding development of a calibration is sought. This is part of the research project for dynamic calibration.
