Both Hexapods abdgantry machines can be transported through phases X, Y, and Z. Which implies that they travel with multi-axial movements? Hexapods have six degrees of freedom and are very capable of attaining accuracy in motion control tools. Gantry systems can as most travel in the xyz plane. When combining several linear stages that achieve motion in the x-axis one uses brackets in order to construct xy or xyz stages. However, every hexapod has one element prevalent in its structural design. Each one of their six actuators has joints and the structural design of the hexapod generally include Ball bearings and roller bearings.
When it comes to positioning and optimal resolution of systems in micrometer and nanometer ranges, gantry devices and Hexapods offer a lot of advantages. That’s probably why Hexapods are better superior for some operations with piezo stages, as compared to the XY stage, XYZ stage, and the linear stage positioning systems. Since they have six legs as opposed to the two or three legs that are common with other types of robots, hexapods offer greater flexibility and accuracy. For improved rigidity and strength in Hexapods, you can upgrade them with piezoelectric force sensors.
Piezoelectric motor and piezo actuators
Piezo motor are electric motors that use induced piezoelectric effect to stimulate vibrations and generate motion in its movement regadless of it being rotational stages, or any other motion control stage. The electric current generated with this piezoelectric induction can be analyzed by means of an electric charge detector.
In order to achieve the highest-precision possible in hexapods, most manufactures use Piezo actuators instead of the regular actuators. This is common in some hexapods that PI designed for precision tools. As a result, they’re able to avoid certain errors and enjoy greater flexibility and rigidity with the Hexapods. What’s more, the hexapods will have higher load capacities.
