Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing robot plan online adjustment. A method includes receiving an initial plan for performing a particular task with a robot having a sensor. The initial plan defines an initial path having a plurality of waypoints. Each waypoint is associated with a target position and a target velocity. The method includes generating an alternative path from the initial path. Generating an alternative path includes generating a plurality of alternative paths including performing respective modifications to one or more waypoints in the initial plan, evaluating each alternative path according to a simulated total time duration required for the robot to traverse the alternative path, and selecting an alternative path having a total time duration that is less than a total time duration of the initial plan.

Provided are a service robot and a display control method thereof, a controller and a storage medium. The service robot display control method comprises receiving a start signal sent by a human body recognition sensor, wherein the human body recognition sensor outputs the start signal to a controller in the case where a user appears within a predetermined range around the service robot, and controlling the mounted device to start operation in the case where the start signal is received. A first display screen of the robot is in a standby state when there is no user, and when a user approaches the robot, the first display screen starts to light up.

A functional safety system performs safety analysis on three-dimensional point cloud data measured by a time-of-flight (TOF) sensor that monitors a hazardous industrial area that includes an automation system. To reduce the amount of point cloud data to be analyzed for hazardous conditions, the safety system executes a real-time emulation of the automation system using a digital twin and live controller data read from an industrial controller that monitors and controls the automation system. The safety system generates simulated, or shadow, point cloud data based on the emulation and subtracts this simulate point cloud data from the measured point cloud data received from the TOF sensor. This removes portions of the point cloud data corresponding to known or expected elements within the monitored area. Any remaining entities detected in the reduced point cloud data can be further analyzed for safety concerns.

A robotic system is disclosed. The system includes a communication interface that receives, from one or more sensors deployed in a workspace, sensor data indicative of a current state of the workspace. The system includes one or more processors that use the sensor data to estimate a state of one or both of the pallet or other receptacle and the set of zero or more items stacked on or in the receptacle, and use the estimated state to generate or update a plan to control a robotic arm to place a next set of items on or in, or remove the next set of items from, the pallet or other receptacle, the plan comprising an ordered sequence of item placements or removals. The plan is generated or updated based at least in part by performing a bounded tree search in which a subset of possible ordered sequences is explored.

Provided is an automotive glass setting apparatus, including a setting base supporting a glass having a plurality of edges, a plurality of alignment units allowing the glass to be aligned with the setting base; a scanning unit scanning the edges of the glass, a plurality of moving mechanisms moving the plurality of alignment units, and a controller controlling the moving mechanisms based on data scanned by the scanning unit to align a center of the glass with a center of the setting base.

The present invention is the invention for providing a guidance service by using a robot. For example, the robot may provide the guidance service in an airport. The robot may receive a destination, acquire a movement path from a current position to the destination, and transmit the movement path to the mobile terminal. The mobile terminal may receive the movement path from the robot and display a guidance path representing a movement path and a user path representing a position movement of the mobile terminal and overlapping the guidance path.

Systems and methods for detecting an escalator in a surrounding environment by a robotic apparatus are disclosed herein. According to at least one exemplary embodiment, an escalator may be determined based on an escalator detection parameter being met. The escalator detection parameter my further require detection of two side walls separated by a distance equal to a width of an escalator and detection of a depreciation in a floor equal to that observed between a stationary portion and a moving first step of an escalator.

Provided is a method of providing food to a user, the method including determining to provide first food among the food to the user; moving a first gripper to a container that contains the first food, determining whether the first gripper reciprocates in the container, calculating a weight difference value indicating an amount of change in a total weight of the food before and after the reciprocating in response to a determination that the first gripper reciprocates in the container, and determining that the first food is provided to the user based on the weight difference value. In addition, an apparatus for providing food to a user to perform the food providing method is provided. Also, a non-transitory computer-readable storage medium storing programs to perform the food providing method is provided.

An arm-type assistance device includes a pillar, a first support portion, a first arm, a second support portion, a second arm, a third arm, an operating unit, and a cargo holding unit. The first arm includes a first member, a first air cylinder, and a second member. The first support portion, the first member, the second support portion, and the second member form a parallel linkage. The parallel linkage is assisted by the first air cylinder. The arm-type assistance device further includes a controller that is configured to control pressure of first air cylinder. The third arm includes a second air cylinder. The controller controls pressure of the second air cylinder. A dimension in an axial direction of the second arm is greater than a dimension in an axial direction of the first arm.

Disclosed are a robot system and an operation method thereof. The robot system includes a central controller, a robot configured to communication with the central controller and capable of autonomous driving, and a first sensing module configured to communicate with the central controller, to be mounted inside an elevator, and configured to measure an electric power of a communication radio wave emitted by a mobile communication device inside the elevator. The robot may transmit or receive a wireless signal on a mobile communication network established according to 5G communication.
