Parallel Kinematic Robotics

Parallel Kinematic Robotics ALIO Industries (patented) parallel kinematic 3 axis and 6 axis robotic systems promise to revolutionize the manufacturing processes of products requiring nanometer resolution and repeatability. With 5 nanometer resolution revolving around a virtual point in space coupled with speeds of up to 110 mm/sec these robotic products form the basis of the next generation of automated nano-positioning systems for the most demanding applications in photonics, packaging, test, micro machining, government, measurement, medical and semiconductor manufacturing. The inherent nature of the design means that settling times after a move are less than 2 ms with no servo dither. In addition, the frictional force between the linear motor and the motion linkage means no hysteresis or loss of position if the power is lost. The Hexapod and Tripod with additional preparation can meet Class 10 clean room standards. We can also provide systems that will work in vacuum chambers 10 to the minus 10 Torr. Plus the robotic systems have no electromagnetic generation.

To assure performance of complex forward and inverse kinematic equations in a parallel structure the controller system is critical

This capability permits the motion for the machine to be programmed in the natural coordinates of the tool-tip, usually Cartesian coordinates, whatever the underlying geometry of the machine. The "forward-kinematic" calculations use the joint positions as input, and convert them to tool-tip coordinates.
