Abstract: Methods for operating robotic devices (i.e., “robots”) that employ adaptive behavior relative to neighboring robots and external (e.g., environmental) conditions. Each robot is capable of receiving, processing, and acting on one or more multi-device primitive commands that describe a task the robot will perform in response to other robots and the external conditions. The commands facilitate a distributed command and control structure, relieving a central apparatus or operator from the need to monitor the progress of each robot. This virtually eliminates the corresponding constraint on the maximum number of robots that can be deployed to perform a task (e.g., data collection, mapping, searching). By increasing the number of robots, the efficiency in completing the task is also increased.

Abstract: A method for providing independent static and dynamic models in a prediction, control and optimization environment utilizes an independent static model (20) and an independent dynamic model (22). The static model (20) is a rigorous predictive model that is trained over a wide range of data, whereas the dynamic model (22) is trained over a narrow range of data. The gain K of the static model (20) is utilized to scale the gain k of the dynamic model (22). The forced dynamic portion of the model (22) referred to as the bi variables are scaled by the ratio of the gains K and k. The bi have a direct effect on the gain of a dynamic model (22). This is facilitated by a coefficient modification block (40). Thereafter, the difference between the new value input to the static model (20) and the prior steady-state value is utilized as an input to the dynamic model (22). The predicted dynamic output is then summed with the previous steady-state value to provide a predicted value Y.

Abstract: A tool changer comprising a master module and a tool module includes a rapid-connect communication bus between the master and tool modules. A unique tool identification number, along with other tool-related information, may be transmitted from the tool module to the master module within about 250 msec of the master and tool modules coupling together. The master module includes a robotic system communications network node connected to the rapid-connect communication bus, and operative to transmit data between the tool and the network via the communication bus. The need for a separate network node in the tool module is obviated, reducing cost and reducing the start-up time required to initialize such a network node upon connecting to a new tool. The rapid-connect communication bus may be a serial bus.

The expert machine should be a substitute for unskilled labor performed at workstations characterized by repetitive activities. An expert machine is defined as a machine that performs a specific task; the knowledge applied to the machine should be used to perform a repetitive task professionally. Predefined trajectory is defined as the actual trajectory that the slave expert machine should follow. The slave expert machine should move along a known predefined trajectory whose parameters have been calculated prior to start-up of the motion. It is assumed that the trajectory is given as function of time and the disturbances are well known. A Master Expert Machine (MEM) is incorporated with sensors for sensing and reading joint motions. It features excellent follow-up attributes and records motion activity in its memory by a process of “machine learning” within the study area.

Abstract: An interacting term existing in a control system is decoupled on the basis of a regular condition of a decoupling matrix. Then, an hyperplane &sgr; which has been obtained to satisfy the Lyapunov stability condition is designed. A control quantity is converged along the hyperplane &sgr;. In this case, even if the uncertainty is generated in a C matrix for connecting a state variable x(t) and an output y(t) of an object to be controlled, it is possible to converge the control quantity while always satisfying the Lyapunov stability condition. A non-linear input gain ki (x,t) used in the control system is designed to be greater than a predetermined value when there is no uncertainty in the C matrix to satisfy the Lyapunov stability condition. Also, a control input signal based upon the sliding mode decoupling control is converted to an articulation torque by a Jacobian. Also, for the control input signal, reverse dynamics of non-linear force are added thereto.

Abstract: A robot control apparatus does not require an expert to perform programming, prepare teaching data or reprogram the motions of a work robot. The controller for the robot accepts the teaching point instructed by a beginner operator, and computes the start and end points in a track from the input teaching points. The controller also computes target start and end points in each of the passes in the track based on the current track points and the overspray width input by the operator and automatically allows for the overspray width. The control apparatus therefore facilitates operation of painting tasks which conventionally required a labor-intensive effort in reprogramming by an expert operator.

Such processes are performed to all operation factors extracted from the car-type classified operation registration file to form a series of programs. Interlock information between manipulators is added to the series of programs to automatically generate teaching data.
