摘要:
A computer-implemented method of engineering autonomous system with reusable skills includes displaying a graphical user interface simulating a physical environment. The graphical user interface depicts one or more simulated objects corresponding to one or more physical objects. Graphical markers are created on the simulated objects based on instructions provided by a user via the graphical user interface. The position and orientation of each graphical marker is determined with respect to the simulated objects. A skill function is created which comprises a functional description for using a controllable physical device to interact with the physical objects based on the position and orientation of each graphical marker. Executable code operable to perform the skill function is created and used to actuate the controllable physical device.

A method and system for determining at least one property associated with a selected axis of a manipulator (2). The elasticity of the links (4, 6, 9, 10, 13, 14) and joints (3, 5, 7, 8, 11, 12) of a manipulator (2) can be modeled and the resulting compliance can be determined. A certain method is used to control the manipulator (2) such that certain quantities related to actuator torque and/or joint position can be determined for a certain kinematic configuration of the manipulator (2). Depending on the complexity of the manipulator (2) and the number of properties that are of interest, the manipulator (2) is controlled to a plurality of different kinematic configurations in which configurations the quantities are determined. Thereafter, a stiffness matrix (K) for each component of the manipulator (2) can be determined, and a global stiffness matrix (MSM) for the total manipulator (2) can be determined in order to determine at least one property of the selected axis.

A method and system to provide improved accuracies in multi jointed robots through kinematic robot model parameters determination are disclosed. The present invention calibrates multi-jointed robots by using the chain rule for differentiation in the Jacobian derivation for variations in calculated poses of reference points of a reference object as a function of variations in robot model parameters. The present invention also uses two such reference objects and the known distance therebetween to establish a length scale, thus avoiding the need to know one link length of the robot. In addition, the present invention makes use of iterative methods to find the optimum solution for improved accuracy of the resultant model parameters. Furthermore, the present invention provides for determination of the end joint parameters of the robot, including parameters defining the tool attachment mechanism frame, which allows for interchange of tools without subsequent calibration.
摘要:
An apparatus and a method for generating acceleration and deceleration patterns for control of a robot in a servo system which is equipped with a plurality of driving axes so constituted as to mutually exert dynamic interference, in such a manner that a synchronism is attained at acceleration start points, velocity peak points and deceleration end points in the patterns for the individual driving axes. Peak time calculating means responds to the information relative to dynamic parameters from constant setting means and command means, and calculates the peak time, which is required until the velocity reaches its peak after the pattern generation start point, from the kinetic energy consumed for each displacement and also from the power distribution relative to the driving sources. And pattern generating means generates, on the basis of the peak time thus obtained, an acceleration pattern and a temporally reflected deceleration pattern for each driving axis, whereby the tact time required for each displacement can be minimized.
