MiR 250

MiR 250

The MiR250 is a more flexible AMR that can work around the clock and is brilliantly simple to setup, for improved productivity. Its smaller footprint and increased adaptability help optimize internal logistics without changing layout.



The MiR250 has a footprint of 580 x 800 mm and a height of only 30 centimeters while still being able to move as much as 250 kg with a speed of 2 meters/second. This makes the AMR more agile than any other AMRs on the market and highly adaptable for challenging environments. Thanks to the small footprint, it can drive in spaces as narrow as 80 centimeters. So, doors and elevators that can be an obstacle for other mobile robots, are not a problem for the MiR250.

The MiR250 is constructed for long lifetime, easy serviceability and work 24/7 with the option for fast battery swap. Further, it has been designed according to current applicable safety standards – we therefore believe it’s the safest AMR on the market.

If you have the need the MiR250 also comes in an ESD version.
