| The pose that this inertia is defined in. | |
A 6x6 spatial algebra matrix used for dynamics calculations.
The matrix is represented by: | -hx*m I*m | | J - hx*hx*m hx*m | where hx is the skew symmetric matrix determined by h (h is the vector from the origin of the reference frame to the center of mass) and I is the identity matrix. The inverse of this matrix is: | -inv(J)*hx inv(J) | | I/m - hx*inv(J)*hx hx*inv(J) |
