05 Mar 2010 Nanopositioning specialist PI has shown its latest 6-axis robotics alignment system - the M-810 parallel kinematics Hexapod at the Photonics West conference The miniature hexapod system provides more than 10 lbs of force and motion in all six degrees of freedom. It can be used for manufacturing and placing of parts requiring very high precision, for microscopy applications or laser and optical alignment.

Parallel Kinematics Advantages
Parallel-kinematic motion systems have a number of advantages over standard serial kinematic (stacked) positioning systems:
Virtual Pivot Point: Rotation Around any Point, not unlike the Human Hand
Only one Moving Platform, No Accumulation of Guiding and Lever-Arm Errors
No Moving Cables for Improved Reliability and Precision
Smaller Package Size
Increased Stiffness, Better Dynamics |
