However, only qualified personnel who have read and understood this manual and the AMR user’s guide should manually move the AMR. The brakes on the drive wheels can be released with the brake release button.
This requires battery power, and an E-Stop must be pressed on the AMR. NOTE: The LD-130CT, LD-90x and LD-250 are difficult to move, even with the brakes released. The LD-250 has a lever to unlock the gearbox. making it easier to move it manually. Releasing an E-Stop ! WARNING: INJURY OR PROPERTY DAMAGE RISK: If the AMR’s E-Stop is triggered, ensure that the cause of the E-Stop is resolved, and all surrounding areas are clear and safe before releasing the E-Stop. After the E-Stop button has been manually released, the AMR will wait until the motors are manually enabled.
Once the motors are enabled, the AMR will wait two seconds and then resume commanded motion, if there is adequate space to maneuver. 2.2 Definitions Platform : The basic part of the robot, including the chassis, drive assemblies, suspension, wheels, battery, lasers, sonar, a core with gyroscope, navigation software, connectors for inter- facing with and powering the payload structure, and platform covers.
