A robotic device including one or more proximity sensing systems coupled to various portions of a robot body. The proximity sensing systems detect a distance of an object about the robot body and the robotic device reacts based on the detected distance. The proximity sensing systems obtain a three-dimensional (3D) profile of the object to determine a category of the object. The distance of the object is detected multiple times in a sequence to determine a movement path of the object.

A device for indicating appropriate social distancing includes the ability to project light (in various forms and in a various ways) onto the ground in a manner visible by the user and those around them. A boundary of the projected light can be set to an acceptable social distance and can include different colors to indicated varying social distances for varying levels of trusted individuals. Proximity sensors set to appropriate distancing requirements, along with the varying levels of trust can be implemented into multiple devices being used in a group setting.

A robot including: a robot body that includes an arm having a longitudinal axis, and at least one joint; and a proximity sensor unit that detects an object approaching the arm of the robot body. The proximity sensor unit includes: a support member that is fixed to the arm of the robot body and that is disposed, at such a position as to extend across the joint of the robot body, so as to be away from a surface of the arm in a direction perpendicular to the longitudinal axis of the arm; and a plurality of proximity sensors that are attached to the support member.

A method for operating at least one robot includes determining the minimum distance of the robot from an obstacle, in particular the closest obstacle to the robot, in particular excluding at least one previously known, in particular temporary, obstacle; reducing the maximum speed of the robot if this minimum distance is below a first minimum distance; and reducing this maximum speed of the robot more if the minimum distance is below a second minimum distance which is smaller than the first minimum distance.

An apparatus for collision avoidance by surface proximity detection includes a plurality of piezoelectric elements disposed adjacent to a surface of an object, a memory storing instructions, and at least one processor configured to execute the instructions to control a first one among the piezoelectric elements to generate an acoustic wave along the surface of the object, and receive, via a second one among the piezoelectric elements, an acoustic wave signal corresponding to the generated acoustic wave. The at least one processor is further configured to execute the instructions to filter the received acoustic wave signal, using a band-pass filter for reducing noise of the received acoustic wave signal, obtain a proximity signal for proximity detection, from the filtered acoustic wave signal, using a linear time-invariant filter, and detect whether an obstacle is proximate to the surface of the object by inputting the obtained proximity signal into a neural network.

An indoor location system includes mobile transceiver units to support a manufacturing control of process courses in an industrial manufacturing of workpieces in a manufacturing plant. The indoor location system includes an analysis unit configured to determine a position of a mobile transceiver unit to be localized from runtimes of electromagnetic signals between transceiver units, and an energy consumption control unit configured to output a control signal for deactivating a localizing mode of a position signal module of at least one of the mobile transceiver units if participation of the at least one mobile transceiver unit in position determination operations is not required and to output a control signal for activating the localizing mode of the position signal module of the at least one of the mobile transceiver units from a deactivated state when participation of the at least one mobile transceiver unit in a position determination operation is required.
