Inertia

class compas.robots.Inertia(ixx=0.0, ixy=0.0, ixz=0.0, iyy=0.0, iyz=0.0, izz=0.0)[source]

Bases: compas.data.data.Data

Rotational inertia matrix (3x3) represented in the inertia frame.

Since the rotational inertia matrix is symmetric, only 6 above-diagonal elements of this matrix are specified here, using the attributes ixx, ixy, ixz, iyy, iyz, izz.
