Perhaps you should try some spelling variations:
rotatory inertia » rotary inertia, rotational inertia
robots inertia » robots inertial, habits inertia, robots initial
motion inertia » motion intention
rotor inertia » rotary inertia, monitor inertia

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((rotor inertia) OR (robots inertia))) OR (motion inertia))) OR (rotatory inertia)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((rotor inertia) OR (robots inertia))) or (motion inertia))) or (rotatory inertia))".
• Adding a wildcard symbol may retrieve word variants: ((((((rotor inertia) OR (robots inertia))) or (motion inertia))) or (rotatory inertia))*.
