Patent number: 12379723Abstract: A method includes operating an autonomous mobile robot (AMR) in a first physical location according to a first safety protocol of the AMR and based on a location of the AMR relative to a second physical location different from the first physical location and with a second safety protocol different from the first safety protocol, switching the AMR to operate under the second safety protocol rather than the first safety protocol while the AMR is located in the second physical location. The method also includes, in response to detecting that the AMR is exiting the second physical location after the AMR has completed operating in the second physical location, switching the AMR to operate under the first safety protocol.Type: GrantFiled: August 29, 2022Date of Patent: August 5, 2025Assignee: Amazon Technologies, Inc.Inventors: Gabriel Hebert, Paul Tomashevskyi, Adam Robert Lehmann, Justin Croyle, Adam Joseph Greenbaum, Christopher John Schuchmann, Erik Edward Steltz, Renen Bassik

Patent number: 12254443Abstract: Embodiments describe techniques for controlling picking robots to retrieve items on the floor and return them to an appropriate location. In one embodiment, the picking robots wait until a sensor in a monitored area (e.g., a designated robot area or an area around a pick/stow station) detects a dropped item on the floor. A central control system then dispatches the picking robot to the location to retrieve the dropped item. In another embodiment, when not being dispatched, the picking robots patrol the area looking for dropped items.Type: GrantFiled: December 4, 2020Date of Patent: March 18, 2025Assignee: Amazon Technologies, Inc.Inventors: Gregory Cartagena, Gabriel Hebert, Caroline Anne Keely, Jonathan Lee Zerez

Patent number: 12220813Abstract: Systems and techniques for performing a calibration test of an obstacle detection sensor of a drive unit are described. An example system includes a calibration region and at least one drive unit. The calibration region is disposed in an environment and includes a calibration apparatus. The at least one drive unit is operable to autonomously move throughout the environment. The at least one drive unit includes a sensor configured to detect one or more objects within the environment. The at least one drive unit is configured to autonomously transition to the calibration region upon detecting at least one predetermined condition, and perform a calibration test of the first sensor at the calibration region using the calibration apparatus.Type: GrantFiled: June 29, 2021Date of Patent: February 11, 2025Assignee: Amazon Technologies, Inc.Inventors: Dincer Bozkaya, Sara Jean Woo, William Joseph Klein, Jing Ma, Gregory Cartagena, Justin Croyle, Gabriel Hebert, Fahrudin Alagic, Stephen A.

Patent number: 12215009Abstract: Autonomous mobile robots having vertical height extension systems for augmented visibility may include a drive mechanism, a lift mechanism, and a vertical height extension including an extension mechanism and a vertical indicator. The vertical height extension may be actively or passively actuated between lowered and raised positions. In addition, the vertical height extension may include a breakaway feature to prevent raising or cause lowering of the vertical indicator in the presence of a payload above the robot. Further, the vertical height extension may include various actuators, emitters, or elements to communicate various attributes of the robot to human associates in proximity, thereby promoting safe, collaborative operations.Type: GrantFiled: May 12, 2022Date of Patent: February 4, 2025Assignee: Amazon Technologies, Inc.Inventors: Tim Martin, Dincer Bozkaya, Matthew Anthony Brady, William Clem, Timothy G. Dietz, Gabriel Hebert, Dragan Pajevic

Patent number: 11591023Abstract: A drive unit of a robotic vehicle including a top surface having a mounting interface to interchangeably couple with multiple different modular payload structures configured to transport items in a facility, workspace or inventory management environment. The mounting interface is configured to securely engage with a mounting portion of the variety of different payload structures to enable a versatile exchange of the payload structure for different conveyance applications. The drive unit includes an electrical interface to communicatively couple with the modular payload structures. The drive unit is configured to use data communicated via the electrical coupling and interface to identify a type of modular payload structure that is mechanically coupled to the mounting interface and implement a motion profile (e.g., speed and acceleration parameters) associated with the identified modular payload structure.Type: GrantFiled: June 24, 2019Date of Patent: February 28, 2023Assignee: Amazon Technologies, Inc.Inventors: Christopher Park, Craig Ropi, Gabriel Hebert, Eric Jones

Patent number: 10336150Abstract: Payload properties may be determined utilizing actuator parameter data. A mobile drive unit may transport a payload around a workspace in accordance with one or more safety. To comply with safety policies, a motion controller of the mobile drive unit may limit acceleration and deceleration to safe maximums for given payload characteristics such as payload mass and payload center of gravity. The motion controller may utilize actuators to cause various motions of the mobile drive unit, including motion across a surface, vertical movements of the payload and motion rotating the payload. To ameliorate worst case assumptions about payload characteristics, in accordance with at least one embodiment of the invention, a payload characterization module may obtain information about payload characteristics based on measurements of operational parameters of the actuators.Type: GrantFiled: December 2, 2016Date of Patent: July 2, 2019Assignee: Amazon Technologies, Inc.Inventors: Gabriel Hebert, Erica Aduh, Peter Thomas Colantonio, Parris S.

Patent number: 10209682Abstract: Embodiments are directed to an inventory system having one or more drive units that are used, in part, to measure traction of a surface. Traction of the surface may be one of many features that can help with the operation of drive units and may also help avoid collisions between drive units when little room is available between the drive units for navigational errors.Type: GrantFiled: March 9, 2018Date of Patent: February 19, 2019Assignee: Amazon Technologies, Inc.Inventors: Gabriel Hebert, Oliver Christoph Purwin
