Hexapods & Positioning Systems
A hexapod is a robotic manipulator capable听of moving a payload in all six degrees of听freedom: lateral, longitudinal, and vertical听translations as well as roll, pitch, and yaw听rotations. Motions can be made simultaneously听in multiple axes or independently in a single axis听while preventing movement in the others.听A hexapod鈥檚 parallel actuator arrangement听provides high load capacity, stiffness, and听accuracy compared to serial robotic manipulator听architectures. Other motion control devices typically provide positioning, motion听simulation, or vibration isolation in only one or two degrees of freedom making听hexapods the ideal solution when multiple degrees of freedom motion is required.
Precision Positioning Hexapods
Precision positioning hexapods are used for point-and-hold or slow tracking operation where minimum incremental听step size, repeatability, and/or accuracy are critical.听

Motion Simulation Hexapods
Motion simulation hexapods are used for high frequency motion replication and disturbance generation. Our听systems use voice coil actuators to provide large accelerations and high bandwidths.听

Vibration Isolation Hexapods
Vibration isolation hexapods are used to isolate a payload from a base disturbance source or isolate the base听structure from a payload-induced disturbance.听

Custom Systems
Sometimes the hexapod needs to match the application rather than trying to听make the application match the hexapod. We are able and willing to modify our听standard hexapods to meet specific customer requirements including extreme听environments. For unique applications, we also build custom hexapods that听leverage off our heritage designs. If you cannot find a standard hexapod that听meets your needs, please contact our engineering team to discuss.
Space Test Simulation Solutions
Vibration Isolation Benches
Ultra-precise metrology systems and test facilities for large space optics require extremely stable, quiet environments. Moog鈥檚 vibration isolation benches mechanically decouple the bench from facility disturbance sources including pumps, machinery, or nearby vehicle traffic.
Gravity Offloaders for Zero Gravity Simulation
Gravity influences structures differently on orbit, but those structures must be integrated and validated on the ground. A deployable spacecraft appendage is often mass-optimized for zero gravity performance but unable to support its own weight on Earth.
