Warsash Scientific  presents one of the smallest hexapods featuring a reference-class 6-axis positioning system.
The new PI H-811 6-axis hexapods find application in research, industry, standard and vacuum environments, micromanipulation, laser and optics alignment, biotechnology as well as tool control.
Featuring a vacuum option, the 6-axis hexapods incorporate a parallel-kinematic design for six degrees of freedom making them significantly more compact and stiffer than serial-kinematic systems.
Higher dynamic range and reliability, no moved cables and reduced friction are some of the advantages of the new hexapods, which are also available in a vacuum-compatible version to 10-6hPa.
Key features of PI H-811 6-axis hexapods:
  • Reference-class 6-axis positioning system
  • Travel ranges to 34mm/ 42º
  • Load capacity to 5kg
  • Actuator resolution 40nm
