    摘要: A method for determining a number of load parameters (ml, xl, rl, αl, Ix, Iy, Iz) for a load (6) which is carried by a manipulator. The manipulator comprises a number of links (2, 3, 4) which are movable in relation to one another, a handling member (5) for supporting a tool, which handling member is movable in relation to said links, a number of axes (A1-A6) around which the links or the handling member are/is movable as well as a motor for each axis which drives the movement of the axis in accordance with supplied reference values for the torque of the motor. According to the method, the manipulator adopts two selected axis configurations. A number of identification axes are appointed. The manipulator is run such that the identification axes carry out a plurality of movements according to predetermined patterns. During these movements, the motor torque and the axis angle are measured. The moments of gravitational force of the identification axes are calculated on the basis of measured motor torques during a first movement. The mass inertia is calculated with correlation between measured motor torques and calculated acceleration during a second movement. The load parameters are calculated from the calculated moments of gravitational force and the mass inertias with the aid of the movement equations of the identification axes.

    摘要: 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.

    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.
