The 90FUN Puppy 1 is furnished with intelligent technology that allows the suitcase to roll by itself and prevents it from tipping over. Thanks to its automatic adjustment system, the cabin trolley travels easily over uneven terrain. Multiple interactive assistant modes are offered, e.g. bi-directional (forward and reverse) following, ramp travel and braking. Users have the option of operating the case by remote control or setting up an auto-following mode within a five-metre range.
