Hexapod 6-axis positioning and motion systems provide better multi-axis accuracy repeatability than conventional stacked multi-axis stages and support greater motion profile flexibility in a compacter setting.
The parallel kinematics principle offers extreme versatility and a more compact and stiffer design than conventional, multi-axis positioning systems (serial kinematics or stacked stages). H-840 high resolution hexapods are parallel-kinematic positioning systems, widely referred to as parallel kinematic machines or 6-DOF parallel micro robots. High Performance Parallel-Kinematic Micro Robot Design For applications that require even higher resolution, the H-840.G2IHP variant with minimum incremental motion to 20 nanometers is offered. In contrast, the H-840.D models use brushless servo motors to drive the actuators directly, provide higher dynamics and enable velocities to 60 mm/s. With a precision gear box deployed within each of the six actuators, the H-840.G hexapod models provide higher load capacity and higher resolution. H-840 hexapod positioning systems come in different variants, optimized for specific motion and positioning applications.
PI hexapod 6-axis stages are based on the Stewart Platform parallel kinematics principle, with 6 high performance motorized actuators working in parallel between two platforms. The H-840 hexapod 6-axis precision positioning system provides high resolution motion in 6 degrees of freedom.
