    Abstract: A posture estimating section acquires image data in which images of a person are recorded, to estimate a posture of the person. A motion control section controls the motion of a robot device on the basis of an estimation result of the posture estimating section. A synchronization control section synchronizes a posture of the robot device with the posture of the person estimated by the posture estimating section. A correction processing section corrects the synchronized motion of the robot device made by the synchronization control section.

    Abstract: The techniques and systems herein enable robot management in populated areas. Specifically, a robot management system receives, from a robot system, a requested route and time for the robot system to travel. A dynamic map that includes dynamic and temporal information about an area of the requested route is then used to determine whether the requested route and time are approved, approved with a modified route or time, or disapproved. An approval message, a modified approval message, or a disapproval message is then generated and sent to the robot system. By using the described techniques, municipalities can monitor, manage, and regulate robots across various operators and locations. Doing so may prevent a high density of robots along various routes, disruptions to the services of such robots, and/or disruptions to surrounding pedestrians and vehicles.

    Abstract: An assembly and joining table, such as with weld splatter protection features, are disclosed along with systems and methods for operating the same in at least partially automated fashion. The table includes holders positioned about platform providing a work surface. Parts are placed within at least certain of the holders for joining to create an assembly. The holders include conductive surfaces and may include a sinuous recessed channels for wiring connecting the conductive surfaces to an electrical ground. A controller may operate motors of the table and command operations of robots for material handling and/or joining, such as based on data from a machine vision system viewing the table.

    Abstract: A device for performing maintenance on an object is provided. The device for performing maintenance on an object comprises an attaching means that enables the device to attach to a part of an object, the attaching means being configured to deform in accordance with a shape of a part of the object, a moving means that enables the device to move on the object, and a maintenance means that performs maintenance on the object. In one embodiment of the present invention, the attaching means is configured so that the device maintains a state of attaching to the part of the object by the deformation of the attaching means even when a shape of a part of the object changes in association with the movement.

    Abstract: A robot apparatus is configured to extend a first end effector into a first process chamber and extend a second end effector into a second process chamber. The first process chamber and the second process chamber are separated by a first pitch. The robot apparatus is further configured to retract the first end effector and the second end effector into a rectangular mainframe while maintaining a distance between the substrates bounded by the first pitch throughout a retraction process, and fold the first end effector and the second end effector inward within a sweep diameter defined by a width of the rectangular mainframe.
