Robot, robot control method and robot control program
The robot of this embodiment moves a work tool to points where multiple work-pieces are placed, and executes a process specified at each point where the work-piece is placed. A point sequence memory stores the point where the work-piece is placed. A work-instruction-sequence memory stores a work instruction executed at the point where the work-piece is placed. A work-piece-correction-level memory stores, in association with each other, a work-piece correction level at each point and a parameter of each point where the work-piece is placed. A work-piece-correction counter memory stores a counter indicating to which point the work-piece correction level at the point is reflected.
1. A robot which moves a work tool to points where a plurality of work-pieces are placed and which executes a specified process at the point where each work-piece is placed, the robot comprising:
a point sequence memory storing the point where the work tool is moved;
a work-instruction-sequence memory storing a work instruction causing the work tool to execute a work;
a camera detecting a work-piece correction level at each point before executing the work instruction;
a work-piece-correction-level memory storing, in association with each other, the work-piece correction level at each point detected by the camera and a parameter of the each point;
a work-piece-correction counter memory storing a value of a counter to be reflected on the parameter; and
a control device reading out the work-piece correction level at the points from the work-piece-correction-level memory, when the work tool reads out each point and a work instruction sequence at each point from the point sequence memory,
wherein the control device, at each point, moves the work tool based on the work-piece correction level, and executes the work instruction,
and wherein the work-piece-correction counter memory increments the counter value by 1 whenever the work-piece correction level is stored in the work-piece-correction-level memory, and increments the counter value by 1 whenever the work-piece correction level is read from the work-piece-correction-level memory.
2. A control method for a robot which moves a work tool to points where a plurality of work-pieces are placed and which executes a specified process at the point where each work-piece is placed, the method comprising:
a point sequence storing step for storing the point where the work tool is moved;
a work instruction storing step for storing a work instruction causing the work tool to execute a work;
a work-piece-correction-level detecting step for detecting, by a camera, a work-piece correction level at each point before executing the work instruction;
a work-piece-correction-level storing step for storing, in association with each other, a work-piece correction level at each point detected by the camera and a parameter of the each point;
a work-piece-correction-level reading step for reading out, by a control device, the work-piece correction level at the points from the work-piece-correction-level memory, when the work tool reads out each point and a work instruction sequence at each point from the point sequence memory;
a work-piece-correction counter storing step for storing a value of a counter to be reflected on the parameter, incrementing the counter value by 1 whenever the work-piece correction level is stored, and incrementing the counter value by 1 whenever the work-piece correction level is read out; and
a control step for reading out the work-piece correction level at the points from the work-piece-correction-level memory, when the work tool reads out each point and a work instruction sequence at each point from the point sequence memory,
wherein the control step, at each point, moves the work tool based on the work-piece correction level, and executes the work instruction.
3. A computer program product executing a control program for a robot which moves a work tool to points where a plurality of work-pieces are placed and which executes a specified process at the point where each work-piece is placed, comprising a non-transitory computer-readable medium to cause a computer controlling the robot to execute:
a point sequence storing step for storing the point where the work tool is moved;
a work instruction storing step for storing a work instruction executed at the point where the work-piece is placed;
a work-piece-correction-level detecting step for detecting, by a camera, a work-piece correction level at each point before executing the work instruction;
a work-piece-correction-level storing step for storing, in association with each other, a work-piece correction level at each point detected by the camera and a parameter of the each point where the work-piece is placed;
a work-piece-correction-level reading step for reading out, by a control device, the work-piece correction level at the points from the work-piece-correction-level memory, when the work tool reads out each point and a work instruction sequence at each point from the point sequence memory;
a work-piece-correction counter storing step for storing a value of a counter to be reflected on the parameter, incrementing the counter value by 1 whenever the work-piece correction level is stored, and incrementing the counter value by 1 whenever the work-piece correction level is read out; and
a control step for reading out the work-piece correction level at the points from the work-piece-correction-level memory, when the work tool reads out each point and a work instruction sequence at each point from the point sequence memory,
wherein the control step, at each point, moves the work tool based on the work-piece correction level, and executes the work instruction.
