Abstract
A teaching support method includes: acquiring a movement of a robot arm having at least one joint, and a movement start point where the movement starts; calculating a plurality of candidates for an attitude of the robot arm at the movement start point that is acquired; calculating a state of rotation of the joint as of when the robot arm is moved according to the movement from the movement start point, for each of the plurality of candidates that are calculated; and reporting a result of calculation.
Claims6
A teaching support method for causing a processor to execute a program stored in a memory, the teaching method comprising executing on the processor the steps of:
- acquiring a movement of a robot arm having a plurality of joints, a movement start point where the movement starts, and a plurality of teaching points along which the robot arm moves;
- calculating a plurality of attitude candidates for an attitude of the robot arm at the movement start point;
- calculating a rotation amount of each of the plurality of joints when the robot arm moves between every two adjacent points among the movement start point and the plurality of teaching points for each of the plurality of attitude candidates;
- calculating a plurality of sums of the rotation amounts of the plurality of joints at the plurality of teaching points for each of the plurality of attitude candidates;
- selecting a plurality of lowest values of the plurality of sums at the plurality of teaching points among the plurality of attitude candidates;
- identifying a plurality of attitudes of the robot arm at the plurality of teaching points corresponding to the plurality of lowest values;
- reporting the plurality of attitudes of the robot arm;
- and
- operating the robot arm according to the identified plurality of attitudes.
A teaching support device comprising:
- a memory configured to store a program;
- and
- a processor configured to execute the program so as to:
- acquire a movement of a robot arm having a plurality of joints, a movement start point where the movement starts, and a plurality of teaching points along which the robot arm moves;
- calculate a plurality of attitude candidates for an attitude of the robot arm at the movement start point;
- calculate a rotation amount of each of the plurality of joints when the robot arm moves between every two adjacent points among the movement start point and the plurality of teaching points for each of the plurality of attitude candidates;
- calculate a plurality of sums of the rotation amounts of the plurality of joints at the plurality of teaching points for each of the plurality of attitude candidates;
- select a plurality of lowest values of the plurality of sums at the plurality of teaching points among the plurality of attitude candidates;
- identify a plurality of attitudes of the robot arm at the plurality of teaching points corresponding to the plurality of lowest values;
- report the plurality of attitudes of the robot arm;
- and
- operating the robot arm according to the identified plurality of attitudes.
A non-transitory computer-readable storage medium storing a teaching support program for causing a computer to execute a process by a processor so as to perform the steps of:
- acquiring a movement of a robot arm having a plurality of joints, a movement start point where the movement starts, and a plurality of teaching points along which the robot arm moves;
- calculating a plurality of attitude candidates for an attitude of the robot arm at the movement start point;
- calculating a rotation amount of each of the plurality of joints when the robot arm moves between every two adjacent points among the movement start point and the plurality of teaching points for each of the plurality of attitude candidates;
- calculating a plurality of sums of the rotation amounts of the plurality of joints at the plurality of teaching points for each of the plurality of attitude candidates;
- selecting a plurality of lowest values of the plurality of sums at the plurality of teaching points among the plurality of attitude candidates;
- identifying a plurality of attitudes of the robot arm at the plurality of teaching points corresponding to the plurality of lowest values;
- reporting the plurality of attitudes of the robot arm;
- and
- operating the robot arm according to the identified plurality of attitudes.
