Is it really a factory? Some visitors may have asked themselves that when they visited the stand of the Bosch Rexroth industrial group at the virtual Hanover Fair in mid-April. There was no noise to be heard, no dirty workers to be seen. Instead: an intelligent floor that wirelessly supplies systems with energy, as previously only known from charging points for mobile phones. On top of that, machines that can be quickly moved and reassembled. And everywhere: radio stations that network the equipment pool in real time.
