US 12,722,298 B1 · Robot movement controls based on identifier encoding signals

Abstract

Techniques for controlling robot movement based on identifier encoding signals are described herein. For example, a device can determine a safety state of a physical location indicating a permission to transmit signals. The safety state can be associated with an operation that can be performed at the physical location. The device can be associated with the physical location. The device can transmit, at a first time based at least in part on the trigger, a first signal that indicates a first identifier. The first identifier can match a second identifier available to an autonomous mobile robot (AMR) from a location marker associated with the physical location. The device can transmit, at a second time, a second signal that indicates the first identifier, the first signal and the second signal enabling the AMR to perform the operation.

Dependent claims

A system comprising:

a location marker configured to be installed at a physical location that is stationary and to encode a first location identifier of the physical location;
a device that is separate from the location marker and that is configured to be co-located with the location marker at the physical location and to transmit a signal encoding a permission to operate in the physical location based at least in part on occupancy of the physical location, the signal encoding the first location identifier;
and
an autonomous mobile robot (AMR) configured to:
receive the signal;
determine the first location identifier based at least in part on an optical read of the location marker;
determine a second location identifier based at least in part on the signal;
determine a match between the first location identifier and the second location identifier;
determine, based at least in part on the match, the permission indicated in the signal;
determine that an operation is permitted in the physical location based at least in part on the permission;
and
perform the operation based at least in part on the operation being permitted.

A method implemented by an autonomous mobile robot (AMR), the method comprising:

determining a first identifier based at least in part on a first signal associated with a location marker, the location marker associated with a physical location that is stationary;
receiving a second signal transmitted by a device that is separate from the location marker, the device associated with the physical location, the second signal indicating a second identifier and encoding a permission to perform an operation at the physical location;
determining a match between the first identifier and the second identifier;
determining, based at least in part on the match, that the operation is to be performed at the physical location;
and
performing the operation at the physical location.
