This paper proposes a new calibration method for joint-dependent geometric errors of six-
DoF industrial robots. Chebyshev polynomials are adopted to characterize the high-order …

Abstract Researchers have studied Stewart–Gough platforms, also known as Gough–
Stewart platforms or hexapod platforms extensively for their inherent fine control …

Determination of the identifiable parameters plays an important role in kinematic calibration
of robot manipulators. For the conventional serial robots, a consensus has been reached on …

We present a simple low-cost calibration procedure that improves the planar positioning
accuracy of a double-arm SCARA robot to levels difficult or impossible to achieve using an …

Three-dimensional (3D) printing technology has been greatly developed in the last decade
and gradually applied in the construction, medical, and manufacturing industries. However …

In this paper, a universal observability index is put forward for optimal measurement
configuration selection in robot kinematic calibration experiments. The effectiveness of two …

Kinematic calibration of a 5 degree-of-freedom parallel kinematic machine (T5 PKM)
resorting to a step-by-step strategy is carried out, which conducts the identification modeling …

Parallel kinematics machine has attracted attention as machine tools because of the
outstanding features of high dynamics and high stiffness. Although various calibration …

Abstract Stewart platform-based Parallel Kinematic Machines (PKM) have been extensively
studied by researchers due to their inherent finer control characteristics. This has opened its …

The hybrid machine tools, combining the advantages of serial and parallel type machine
tools, provide more and more application opportunities for less-freedom parallel mechanism …
