The TRIPOD product series consists of compact and modular multidimensional positioning systems that combine serial and parallel kinematics in a hybrid design. Compared to classic hexapods, which are limited in rotation around their Z-axis, SmarAct's TRIPODs offer continuous rotation and high stiffness over the entire working range.
Classic hexapods that should be able to rotate continuously around its Z-axis would have to be equipped with a rotation stage on its top plate which would influence system complexity and the overall cost of such a system. The TRIPOD on the other hand includes such rotation capabilities without mechanical and economical drawbacks.
The central component of a TRIPOD positioning system is the 3D TRIPOD Core, a tip-tilt stage offering two rotational and one translational degree of freedom in a very compact design. Because the TRIPOD is fully compatible to the SmarAct Modular System it can be mounted on top of a high precision XY platform made of CLS linear piezo stages.
The top plate offers mounting space for an additional rotation stage, thus creating a modular positioning system with six degrees of freedom whereas the rotation around the Z-axis is continuous by design.
