Results of the workshop at DENSO in Germany

April 2021

The new ROSY LS was presented. DENSO robots of the types VS050 and Cobotta were calibrated.

ROSY LS

The new version of our calibration system.

With ROSY industrial robots are calibrated and their environment measured. According to a holistic approach ROSY measures robots, grippers, workpieces and external axes.

Measurements are carried out close to the process on the shop floor. ROSY can be flexibly mounted in the cell or on the robot.

Based on customer requirements and own experiences as well as own needs, teconsult has the proven measuring and calibration system ROSY new developed.

Exceed after an accuracy check of the robotic system the determined deviations from process requirements or are the requirements for accuracy of the robot is very high, the robot calibration can be used.

ROSY enables the increase of the absolute accuracy of industrial robots.

ROSY is a service tool in a portable case and is available for services from teconsult at the end customer's site.

Interface

There is a web interface for setup. Communication with the controller takes place via an ORIN provider. This provider is implemented prototypically as a b-Cap server.

Setup

The sensor is mounted stationary. No cables are moved along.

Performance Overview

  • Accuracy check
  • Adjust Calset / Mastering / Zero-Offsets
  • Robot calibration and accuracy increase
  • Gripper measurement
  • Workpiece measurement
  • Measurement of external axes

    • Sensor and probe

    We use a hight precision light section sensor. The ball probe is attached on the robot.

    The Unique Advantages of ROSY LS

  • Easy to operate
  • Process-oriented measurement on shop floor
  • Industrial and precise sensor
  • Automated reporting
  • High portability - small size and low weight
  • Versatile service tool

    Results

    The time for the measurement is less than 5 minutes. A total of about 80 measurement poses were approached. The mean error could be improved from 4.784 to 0.057mm. The maximum error from 8.040 to 0.148mm.
