Abstract: A cooperative robotic arm system includes a first robotic arm, a second robotic arm and a controller. The first robotic arm has first working vector. The second robotic arm has second working vector. The controller is configured to: (1) control the first robotic arm and the second robotic arm to stop moving; (2) determine whether a first projection vector of the first working vector projected on a first coordinate axis and a second working vector projected on the first coordinate axis overlaps; (3) when they overlap, determine whether a third projection vector of the first working vector projected on a second coordinate axis and a fourth projection vector of the second working vector projected on the second coordinate axis overlap; and, (4). when they do no overlap, control a controlled-to-moved one of the first robotic arm and the second robotic arm to move along a reset path.

Abstract: A data transfer system is provided. The system includes a plurality of electronic devices and a data transfer management device. The data transfer management device identifies a master device among the electronic devices, and the data transfer device make the master device as a root node of a topology architecture, wherein the master device is configured to provide data. The data transfer device calculates a maximum connection amount according to a first transfer time, wherein the data transfer device selects a plurality of slave devices among the electronic devices according to the maximum connection amount. The data transfer device divides the master device into a transmitting node queue, and arranges the slave devices into a receiving node queue in sequence. And, the data transfer device builds a plurality of layers of the topology architecture and sets a plurality of layer transfers corresponding to the layers.

Abstract: A robotic arm system includes first robotic arm, second robotic arm and main controller. The first robotic arm and the second robotic arm are configured to grab object. The main controller is configured to: determine whether first force vector of first force applied by the first robotic arm to the object is equal to second force vector of second force applied by the second robotic arm to the object; when the first force vector and the second force vector are not equal, obtain a first difference between the first force vector and the second force vector; and according to the first difference, change at least one of the first force applied by the first robotic arm to the object and the second force applied by the second robotic arm to the object so that the first force vector and the second force vector are equal.
