Hexapods and Parallel Kinematics Positioning Systems FAQs

Hexapod positioners are the most versatile multi-axis positioning systems. Often referred to as a Stewart Platform, a hexapod is based on a 6 actuators 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 higher stiffness. In addition, hexapods are more flexible than conventional 6-axis positioners.

Why Medical Equipment Design Engineers move towards Piezo Transducers and Piezo Ceramic Motors

Electromagnetic motors and drives have been optimized for more than 100 years. They can be found applications from toys to aerospace systems. With all their advantages, there are limitations such as magnetic fields (undesirable in certain applications), reduced efficiency when it comes to miniaturization as well as bandwidth limitations. Piezo transducers can fill these voids...
