DELIVERY — In-Facility Logistics

The city courier, on your floor.

The narrowest body of any commercial transport robot — just 240 mm. Narrow enough to clear tight doorways and your existing aisles, so you never have to rebuild the floor around it. Parts, documents, medication, instruments, meals — anything carried by hand can hand the last mile of delivery to it. Like a city courier, it threads the back alleys and gets there, door to door.

Three pain points on the floor

PAIN 1

Hand-carrying ties up your people

Staff drop what they're doing to run something across — ten minutes a trip, a dozen trips a day. The people you most want focused on the job, spending their time on the least skilled walking.

PAIN 2

WiFi has holes everywhere

Thick walls, metal cabinets, basements — most sites have dead zones. A typical AMR stops dead the moment it loses the network, and the vendor's first move is to rewire the whole site.

PAIN 3

Magnetic-tape AGVs mean starting over

Marking lanes, laying tape, setting reflectors — change the layout and you redo it all. No one wants to shut the floor down for the sake of one vehicle.

A day in the flow

This is what it actually looks like running on site

Power on, route loads automaticallyThe route script lives on the robot itself, ready the moment it boots — no server, no cloud.
Call it with a buttonStaff press a physical button by their work area and the robot comes. No tablet, no app, nothing to learn.
Deliver through WiFi dead zonesOffline multi-stop routes (an industry first): the script runs on the robot itself, so it completes the whole route even where there's no network.
Give it a shake, off it goesTake your load, shake the robot, and it heads to the next stop; shake it again and it goes home — the most praised interaction in field trials.
Auto-return to chargeIt returns to its dock once the full route is done, ready for tomorrow.

Track record in Japanese manufacturing

Source: Preferred Robotics (manufacturer's public cases)

DENSO 高棚製作所Automated finished-goods transport across four production lines (about 58 trips a day), keeping technicians at their stations.

藤次郎 (knife manufacturing)2 robots run over 1,000 trips a month, fully automating inter-process handoffs.

Demant Japan4 robots travel 110 km a month, moving hearing-aid materials and products through the manufacturing process.

Rinnai 大口工場Deployed for production-line parts replenishment, cutting down operators' walking away from the line.

Not just factories — clinics, dental and pharmacies deliver too

ひのき薬局Inbound medication from the back door is left to the robot, so receiving staff stay focused on dispensing and patients — no more carrying roughly 5 kg of medication per trip.

博多Takano牙科Root-canal equipment and materials delivered to six treatment chairs automatically; the dentist taps an iPad to call it, without leaving the patient.

KK Clinic 市原 (internal medicine)Charts move between the front desk, exam rooms and treatment room, cutting staff legwork and wait times — and lowering fall risk for elderly patients.

温耳鼻咽喉科Instruments move between the sterilization room and exam rooms; the robot walks about 1 km a day, sparing nurses the trips.
