A robot, such an industrial robot, has an arm. The arm has a plurality of rotation members, a plurality of joints each rotatably and mutually connecting adjacent two rotation members, and a plurality of electric servo motors respectively driving the joints. In this robot, every operation cycle, an angular speed is calculated at which to drive each servo motor, and a speed of a monitoring portion set in each rotation member is calculated. It is then determined whether or not the speed at the monitoring portion is equal to or lower than a reference speed. When it is determined that the speed at the monitoring portion is over the reference speed, the angular speed of each servo motor is instructed to reduce such that the speed at each monitoring portion becomes the reference speed or lower. The servo motors are driven at the angular speed that has been reduced.

Method and apparatus for controlling operations of robot

A robot operation apparatus includes touch panel, touch operation detecting unit, action command generating unit, and selection operation detecting unit. The action command generating unit is capable of performing an operation determining process and an action command generating process. The operation determining process is a process for determining a drive axis or an action mode of a robot to be operated based on the selection operation detected by the selection operation detecting unit, and when a touch operation detected by the touch operation detecting unit is a drag operation, determining a movement amount of the drag operation. The action command generating process is a process for determining a movement amount of the robot based on the movement amount determined by in the operation determining process, and generating an action command for moving the robot at the drive axis or in the action mode to be operated by the movement amount.

Robot operation apparatus, robot system, and robot operation program

In a robot operation apparatus, a motion command generator selects one of combinations of driving axes as an operation object from among preset combinations of the driving axes including at least one of: a driving axis associated with drag operation in a first direction for a touch panel; or a driving axis associated with drag operation in a second direction intersecting with the first direction. If touch operation detected by a touch operation detector is the drag operation, the motion command generator determines whether drag operation is in the first direction or the second direction. The motion command generator generates a motion command to drive the driving axis associated with drag operation in the first direction, if drag operation is in the first direction, and generates a motion command to drive the driving axis associated with drag operation in the second direction, if drag operation is in the second direction.

In an axis angle determination method, an angle or a position of each axis of a six-axis robot is determined. The robot is capable of taking an attitude of a singular point being a state in which rotation axes of fourth and sixth axes match. Based on teaching results of a position and attitude of a hand by point-to-point teaching, the method judges whether an attitude of the robot in which the angle or the position of each angle is to be determined next is a singular point. If judged that the attitude is the singular point, angles of the fourth and sixth axes required for the six-axis robot to move to the singular point are determined such that an angle of one of the fourth and sixth axes is fixed to a current value and an angle of the other axis is determined based on the fixed angle.
