Methods, systems and apparatuses are disclosed for non-destructively a substrate using ultrasound waves, and enhancing resolution of imaging created from ultrasound signals that are back reflected from a substrate surface second, or back surface by maintaining the incident angles of the ultrasonic beams at the substrate second surface such that the ultrasonic beams strike the substrate second surface at an angle that is substantially perpendicular to the complex geometric profile of the substrate second surface by supplying known spatial coordinates to the system to maintain the incident angles of the ultrasonic beams at a predetermined angle relative to the substrate second surface.

In a robot, an actuator causes the robot to operate. A processor is configured to acquire, when a holding portion is held by a predetermined target, physical information on a physical function of the predetermined target, and cause, by controlling the actuator depending on the acquired physical information, the robot to perform at least one of an examination operation for examining the physical function of the predetermined target and a training support operation for training the physical function of the predetermined target.

A control apparatus that controls a robot including a dispenser and range sensors includes a control unit, and the control unit controls a robot arm, when the dispenser is moved in a first moving direction, to place the first range sensor anterior and calculates an amount of ejection using a difference between values detected by the first range sensor and the second range sensor forming a set and controls the robot arm, when the dispenser is moved in a second moving direction, to place the third range sensor anterior and calculates the amount of ejection using a difference between values detected by the third range sensor and the fourth range sensor.

A robot comprises: a main PCB having an antenna disposed thereon, the antenna disposed on an upper portion of the main PCB; and a sub-PCB spaced apart from the main PCB in a horizontal direction, wherein the main PCB comprises a non-overlap region that does not overlap the sub-PCB in both the horizontal direction and a vertical direction, and all or any portion of the antenna is disposed on the non-overlap region.

Disclosed are a robot system and a control method for the same. The robot includes a first server, a first robot registered on the first server and configured to deliver goods to a client according to information received from the first server, a second robot configured to receive the delivery goods from the first robot, and a second server having the second robot registered thereon and being configured to operate the second robot. The control method for the robot system may include: confirming, by the first robot, whether a person is present in a surrounding area of delivery destination; when someone is present, acquiring, by the first robot, voice information and image information of the present person and transferring the same to the second robot; transferring, by the second robot, the voice information and the image information of the person to the second server; recognizing, by the second server, a person from at least one of the voice information and the image information of the person transferred from the second robot, and transferring a recognition result to the second robot; confirming, by the second robot, whether the present person is a family member of the client, based on the recognition result of the person transferred from the second server; and when the present person is a family member, transferring, by the first robot, the delivery goods to the present person.

Embodiments of systems and methods for remotely controlling a robotic welding system over a long distance in real time are disclosed. One embodiment is a method that includes tracking movements and control of a mock welding tool operated by a human welder at a local site and generating control parameters corresponding to the movements and control. The control parameters are transmitted from the local site to a robotic welding system at a remote welding site over an ultra-low-latency communication network. The round-trip communication latency over the ultra-low-latency communication network is between 0.5 milliseconds and 20 milliseconds, and a distance between the local site and the remote welding site is at least 50 kilometers. An actual welding operation of the robotic welding system is controlled to form a weld at the remote welding site via remote robotic control of the robotic welding system in response to the control parameters.

A mobile home robot is provided. The mobile home robot includes a storage configured to store in-home map data, a communication interface comprising communication interface circuitry, a camera, a user interface, and a processor configured to, based on device information of a plurality of Internet of things (IoT) devices installed in the home and an image captured through the camera while the mobile home robot moves around in the home, generate location information of each of the plurality of IoT devices, to map the generated location information with the map data, and in response to a user command being received through the user interface, to provide an IoT device location-based service based on the map data with which the location information is mapped.

Noise reduction in a robot system includes the use of a gesture library that pairs noise profiles with gestures performed by the robot. A gesture to be performed by the robot is obtained, and the robot performs the gesture. The robot's performance of the gesture creates noise, and when a user speaks to the robot while the robot performs a gesture, incoming audio includes both user audio and robot noise. A noise profile associated with the gesture is retrieved from the gesture library and is applied to remove the robot noise from the incoming audio.

A robot comprises: a main PCB having an antenna disposed thereon, the antenna disposed on an upper portion of the main PCB; and a sub-PCB spaced apart from the main PCB in a horizontal direction, wherein the main PCB comprises a non-overlap region that does not overlap the sub-PCB in both the horizontal direction and a vertical direction, and all or any portion of the antenna is disposed on the non-overlap region.

A compound sensor that is capable of being used with robotics is provided such that the compound sensor includes a distance measurement unit and a pressure measurement unit. Further, a contact detection unit, which is dedicated to performing a detection when a measurement target contacts with a surface of the sensor is included.
