to a stop. The AMR traveled in a combination of straight and arced trajectories for the full range of
valid translational and rotational velocities.
Test Assumptions:
• Robot payload: 650 kg (MD-650), 900 kg (MD-900)
• Velocities tested (AMR maximum): 100 to 2200 mm/s (MD-650), 100 to 1800 mm/s (MD-900)
• Floor friction: 0.63 dynamic and 0.76 static coefficient of friction
• Specified Overall Floor Flatness (SOFF): 25 (Moderately Flat)
• Specified Overall Floor Levelness (SOFL): 15 (Conventional)
Stopping distance and time for the AMR are provided below. This information applies to all allowable
payloads.
