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.
Introduction about MIR
Mobile Industrial Robots (MiR) is a mobile platform that allowed you to get things done like never before. MiR is bridge to complete a process from different locations autonomously. The potentials are limitless. The more research you done on MiR, the more you stay ahead from competitors. Contact us to understand more about MiR Robots today.
