Hardware solutions

Vehicles that arrive with the software already running on them. Take a complete vehicle, or take the bare platform and put your own module on the deck.

AMR

One partner for the whole vehicle: the P250 platform base, the navigation software on it, and ACS coordinating the fleet. Everything above the deck plate belongs to the top module and everything below it is platform, so the same base carries a shelf, a conveyor, a SCARA, or an arm — and every vehicle in the family shares one interface.

What is included

Vehicle platform — P250
A modular AMR drive base with a frozen deck interface: 40 M8 inserts at 100 mm pitch and two ø12 H7 dowels. Top modules bolt down and locate the same way on every length in the family.
Navigation software
Sensor fusion combines lidar, landmark, line, vision, and sky guide sensors, so vehicles run reliably even where SLAM alone struggles.
Fleet management — ACS
Route planning and traffic management for dozens of vehicles, including single-lane paths. An ETA-aware route prediction algorithm keeps unnecessary stops and waiting to a minimum.

P250 platform base

The rating is three figures at once, because mass alone means nothing for a base that carries arms: 250 kg static, payload centre of gravity no more than 600 mm above the deck and within ø200 mm of the rotation axis, and 150 N·m continuous deck torque (300 N·m peak).
