A robotic arm system includes a robotic arm having at least one stepper motor and operable to move an end of the robotic arm in X-, Y-, and Z-dimensions, a camera attached to the robotic arm, and a controller coupled to the robotic arm and to the camera. During configuration, the controller moves the end of the robotic arm to a reference point to obtain initial reference coordinates and a reference image, and to a target location to obtain initial target coordinates. During operation, the controller moves the robotic arm according to the initial reference coordinates, adjusts a position of the robotic arm to an actual reference location using the camera to determine actual reference coordinates, and moves the robotic arm to an actual target location using the initial target coordinates and a difference between the initial reference coordinates and the actual reference coordinates.

A robot teaching device capable of simplifying a work involved in teaching a robot. The robot teaching device includes a position data storing section configured to store target position data for a robot; an operation instruction storing section configured to store an operation instruction for arranging the robot at a target position, the operation instruction not including the target position data; and a position data writing section configured to acquire current position data of the robot when the operation instruction is input, the position data writing section further configured to write, to the position data storing section, the current position data as the target position data together with a unique identifier, in which the identifier of the target position data is automatically given to the operation instruction being input to teach an operation to the robot.

A two-phase liquid immersion cooling system is described in which heat generating computer components cause a dielectric fluid in its liquid phase to vaporize. Advantageously an absorption/desorption unit is employed having a carbon element and a controller configured to regulate the absorption unit.

An attachment device attaches a plurality of attachment target members to an attachment portion formed in a circumferential direction of a rotating main body portion. A first measurement unit measures a physical amount concerning a perimeter of the attachment portion. An attachment unit attaches, to the attachment portion, the plurality of attachment target members selected based on the physical amount concerning the perimeter measured by the first measurement unit. A second measurement unit measures a physical amount concerning a gap between the adjacent attachment target members to be attached by the attachment unit.

A system includes a robot with a robot arm having multiple joints and an end effector to carry a substrate. A processing device is to build, with respect to a joint space for the multiple joints and the end effector, a graph of reachable positions and sub-paths between the reachable positions, wherein the reachable positions and the sub-paths satisfy Cartesian limits within the joint space. The processing device is to determine, by executing a graph optimization algorithm on the graph, multiple paths, each made up of a group of the sub-paths and having one of a shortest distance or a lowest cost between a start point and an end point of the end effector. The processing device is to select a path, of the multiple paths, through the graph that minimizes a move time of the end effector between the start point and the end point.
