Abstract

Purpose

The purpose of this paper is to investigate the vibration suppression of industrial track robot and propose a practical solution.

Design/methodology/approach

Root‐cause analysis through dynamic modeling, and vibration suppression using the acceleration smoother.

Findings

The vibration is due to insufficient damping based on the model analysis. The solution achieved significant performance improvement without redesign of robot hardware and controller.

Research limitations/implications

The design of the proposed acceleration smoother is still empirical based, which is unable to achieve optimal design.

Practical implications

This solution is very easy to implement. It is robust, reliable and is able to generate consistent results.

Originality/value

A very practical industrial solution, especially useful for upgrading the existing systems in the field without redesign the hardware and controller.

Abstract

Purpose

For semiconductor and gene‐chip microarray fabrication, robots are widely used to handle workpieces. It is critical that robots can calibrate themselves regularly and estimate workpiece pose automatically. This paper proposes an industrial method for automatic robot calibration and workpiece pose estimation.

Design/methodology/approach

The methods have been implemented using an air‐pressure sensor and a laser sensor.

Findings

Experimental results conducted in an industrial manufacturing environment show efficiency of the methods.

Originality/value

The contribution of this paper consists of an industrial solution to automatic robot calibration and workpiece pose estimation for automatic semiconductor and gene‐chip microarray fabrication.
