About This Webinar
Hexapods are 6-axis parallel-kinematic machines often employed to solve complex multi-axis precision positioning and motion applications in fields such as photonics, optics, metrology, test and measurement, microassembly, motion simulation, and stabilization. This webinar will begin with a discussion on the basic principles of hexapod controls and software and compare the parallel setup with a serial kinematics setup, illustrating its advantages and limitations and looking into features such as stroke, workspace, precision, size, stiffness, dynamics, and its randomized pivot point functionality. The presentation will include a more detailed look into critical hexapod components, such as joints, and the effects of different drive systems and kinematic structures on applications and environments.

The webinar will also focus on intelligent algorithms and motion systems used for optimization of throughput in applications — such as active alignment of photonics circuits, optics, detectors, and emitters — and discuss the principles of PI’s fast alignment algorithms and the achievable performance with the latest positioning hardware. Further, the presentation will explore the challenge of reducing the complexity of the optical system to a couple of measurable parameters. Based on this knowledge, the presentation will explore how lens assemblies, beam shaping instruments, photonic integrated circuits, and even laser communication systems are tested, built, or operated based on PI alignment algorithms and motion systems. Solutions will be presented that support high throughput based on fast optimization routines and alignment systems.

About the presenters:
Dr. Christian Rudolf is head of Product Division Hexapods at PI and holds a Ph.D. in mechanical engineering. He has more than 12 years of experience in designing complex mechatronic systems and applications, which also implies customer consultation at a very high level. Rudolf has led the group for hexapod design at PI for over six years.

Dr. Michael Oldenburg’s Ph.D. in optics and photonics was received from Karlsruhe Institute of Technology, where he was also recognized for a best publication in the journal Advanced Materials in the field of solar energy from Karlsruhe School of Optics and Photonics. Oldenburg began his PI (Physik Instrumente) career as a technical sales engineer, consulting with customers on their demanding applications. He now joins the team in Singapore as a photonics and industrial automation field application engineer, tasked with building an application and service center to develop and test PI’s motion system on real problems.
