Query: Exoway: an exoskeleton on actuated wheels   In this short work we present a low cost exoskeleton with actuated wheels
that allows movements as well as skating-like steps. The simple structure and
the actuated wheels allows to minimize the use of motors for locomotion. The
structure is stabilized by an active control system that balances the structure
and permit to be maneuvered by the driver whose commands are acquired by a
dedicated hardware interface.
