1. An autonomous mobile device (AMD) comprising:
a first sensor;
a second sensor;
one or more memories storing computer-executable instructions; and
one or more processors to execute the computer-executable instructions to:
determine, at a first time, a first speed value to operate the AMD;
determine, using the first sensor, a first distance value indicative of a distance between the AMD and a first obstacle within a physical space;
determine one or more distance thresholds associated with the first sensor;
determine, using the first sensor, one or more brightness measurements;
determine one or more brightness thresholds associated with the first sensor;
determine, based at least in part on the first distance value, the one or more distance thresholds, the one or more brightness measurements, and the one or more brightness thresholds, a first value;
determine, using the second sensor, a first tilt value indicative of a tilt of the AMD;
determine, based at least in part on the first tilt value, a second value;
determine, based on the first value and the second value, a second speed value that is less than the first speed value; and
operate the AMD at a second time based on the second speed value.
