Configurable service isolation zones for service of equipment employing mobile robots

A safety system is disclosed for failsafe servicing of areas within an order fulfillment facility. During normal operation, a number of battery-powered robots receive wireless instructions from a management control system (MCS) to transfer items to/from workstations or storage shelves in a multi-level storage structure. The order fulfillment facility may be divided into dynamically configurable service zones. When service is required in a service zone, different safety protocols may be employed based on a determination as to the priority level of service required and/or the estimated length of time service will take. One safety protocol involves physically blocking all access points to a service area with mechanical guards, so that order fulfillment operations may be proceed around the service zone while service is performed.

Context-sensitive safety monitoring of collaborative work environments

Various embodiments for enforcing safe operation of machinery performing an activity in a three-dimensional (3D) workspace includes computationally generating a 3D spatial representation of the workspace; computationally mapping 3D regions of the workspace corresponding to space occupied by the machinery and a human; and based thereon, restricting operation of the machinery in accordance with a safety protocol during physical performance of the activity. Limited-access zones are defined within which the presence of a human will not affect operation of the machinery.

Dynamic, interactive signaling of safety-related conditions in a monitored environment

Systems and methods for determining safe and unsafe zones in a workspace—where safe actions are calculated in real time based on all relevant objects (e.g., some observed by sensors and others computationally generated based on analysis of the sensed workspace) and on the current state of the machinery (e.g., a robot) in the workspace—may utilize a variety of workspace-monitoring approaches as well as dynamic modeling of the robot geometry. The future trajectory of the robot(s) and/or the human(s) may be forecast using, e.g., a model of human movement and other forms of control. Modeling and forecasting of the robot may, in some embodiments, make use of data provided by the robot controller that may or may not include safety guarantees.
