    摘要: The robot assembly of an industrial robot comprises a stationary robot component (11) and a plurality of movable robot components (12, 13, 14). At least parts of the stationary robot component and the movable robot components have airtight chambers (15, 16, 17) communicating with each other and intended to be kept at a pressure higher than a predetermined level which is higher than an external atmospheric pressure. Robot driving motors (18 to 23) for driving the movable robot components are arranged within the airtight chambers. A driving motor controller (27) for driving and controlling the robot driving motors is connected to the robot driving motors by means of electric cables arranged within the airtight chambers. Pressure switches (25) supply signals to the driving motor controller to stop the robot driving motors, respectively, upon detection of the pressure in the airtight chambers when the pressure in the airtight chambers drops below the predetermined level.

    摘要: A system for setting a tool coordinate system brings directions ( , , ) of respective basic axes of the tool coordinate system into coincidence with directions (X, Y, Z) of basic axes of a robot reference coordinate system. A tool center point (TCP) serves as an origin, and the system causes a robot to memorize metric values on each motion axis of the robot at the moment of coincidence as setting information for setting the tool coordinate system. The system uses this setting information as information for subsequent robot motion. With the present invention, the setting of tool coordinates, which was a troublesome operation in the prior art, can be performed easily and accurately through a simple method.

A memory (3) is included for storing a calculation sequence of a general expression of a given straight line obtained from an X value of a point (U=0) on the given straight line and the slope of the given straight line on a plane in which a welding condition input value is plotted along the X axis and a command value delivered to a digital/analog converter that applies commands to the welding machine is plotted along the Y axis. A value is obtained by substituting a welding condition input value, which is applied when the welding robot is taught, into the general expression stored in the memory (3), the value obtained being adapted as an output value supplied to the digital/analog converter.
