The isotropic constrain of the standard hexapod imposes special inertia of the top platform which may not be wanted in practice (\\(I\_{zz} = 4 I\_{yy} = 4 I\_{xx}\\)).

A class of generalized Gough-Stewart platforms are proposed to eliminate the above constrains.

|
||||
- Comprehensive and fully parametric model of the hexapod for symmetric configurations are established both in the Cartesian and joint space.
|
||||
- Inertia of the struts are taken into account to refine the model.
|
||||
- A novel approach in order to obtain dynamically isotropic hexapods is proposed.
|
||||
- A novel architecture of hexapod is introduced (Figure [2](#org14fbbb3)) which is dynamically isotropic for a wide range of inertia properties.
