Hexapod Robots in Automotive Applications

As the precision requirements in the automotive industry are increasing, the need for advanced robotics arises. Traditional robots are fast, can handle heavy loads, but lack positioning accuracy. Hexapod robots have a long history in precision alignment & micro-manufacturing automation, but were considered too precise for the automotive industry. The situation is rapidly changing. Modern […]

Novel Sample Stage Alignment Hexapod for X-ray Microscopy and Tomography

Hexapod with Additional Linear Encoders to Achieve the Highest Precision 1. Application: X‑Ray Microscopy / Tomography For synchrotron-based sub-micrometer hard X‑ray Tomography, the sample rotation axis must be aligned very precisely in at least five degrees of freedom with respect to the field of view, the lens, the detector or the beam itself. High stiffness […]

Hexapod in Proof of Concept for High-Speed Interstellar Travel with Directed Energy

The velocity of present-day spacecraft may seem galactic in contrast to what humans experience in their daily commutes involving even the fastest trains, planes or automobiles. However, compared to the warp-drive performance known from science fiction classics such as Star Trek and Star Wars, space travel in the early 21th century still moves at a […]

Hexapod for Drone Testing – 6 Axis Motion Simulator to Improve Image Stabilization

The human brain can do amazing things when it comes to image processing.  Everyone who has taken video while running or just walking has made that experience.  Our brain filters out all the jitter and shake and plays back a reality that is more virtual than real. For the longest time since the inception of […]

Hexapods and Parallel Kinematics Positioning Systems FAQs

Hexapod positioners are often referred to as Stewart Platforms. A hexapod is based on a 6-axis (XYZ, Pitch, Roll, Yaw) actuator system arranged in parallel between a top and bottom platform. PI parallel kinematics (PKM) precision positioning systems have many advantages over serial kinematics stages, such as lower inertia, improved dynamics, smaller package size, and […]

Dental Biomechanics Research Based on Hexapod 6-Axis Platform

Hexapod motion and positioning platforms have traditionally been used in engineering, optics, and physics applications for their ability to provide precision motion in all degrees of freedom and flexibility based on a programmable center of rotation. As hexapods become more mainstream, applications expand into medical fields as well. Dental biomechanics deals with the interactions between […]

Precision Robotics and Automation: Hexapods Advance Production Processes

Summary Hexapods, six-legged parallel-kinematic machines, are quickly gaining ground in a broad range of industrial automation applications after “learning” how to directly communicate with PLC or CNC controllers via fieldbus interfaces. As far as the semiconductor and electronics industry, automobile industry, and precision assembly are concerned, many production processes have become inconceivable without them. Today, […]

6-Axis Parallel Kinematics for UHV Alignment and Active Vibration Cancellation for Semiconductor Applications

Inspection tools in the semiconductor industry, laser alignment and adjustment tools for the next generation of extreme ultraviolet lithography (EUVL) require highly accurate motion, often in all 6 degrees of freedom. Parallel kinematics structures provide an elegant and highly flexible way to achieve precise multi-axis motion. Different designs have found successful applications in 6D precision […]

Hexapod 6-Axis Alignment System Provides Flexibility in Dimensional Measuring Machine in Automotive Applications

The ever higher demand on the performance of headlights in automobiles drives automation and precision requirements of suppliers. A novel compact dimensional measuring machine designed by the DYMACO Group now makes use of 6-axis parallel positioning and alignment system to provide more flexibility for in-line automated dimensional measuring of headlamps in the Automotive Industry. The […]

50 Hexapod 6-DOF Alignment Systems for the Sub-Reflectors of ALMA, the Largest Telescope Project in the World

The ALMA (Atacama Large Millimeter Array) observatory is the largest and most advanced astronomical telescope system in the world. ALMA is not a classical optical telescope but a combination of up to 66 radio-telescope dishes receiving electromagnetic radiation at millimeter and sub-millimeter wavelength.  The combination of many antennas, spread out over a large area, has […]
