Teach-in (technology)

from Wikipedia, the free encyclopedia

Teach-in (English, for example: "learning"; also: teaching ) describes a process for programming a robot . To do this, the programmer acts as a tutor and moves the robot to the desired position using a control panel . All coordinates (points) reached in this way are saved in the control . This step is repeated until an entire work cycle has been run through. The program sequence consists in the robot approaching all saved points autonomously. Parameters can be entered for the movement between the individual points . The speed and acceleration are adjustable, and with some robots it is also possible to specify the required accuracy.

Point-to-Point and Continuous Path

There are basically two different variants when driving the robot:

P2P: Point-to-Point: The robot moves from point n to point n + 1, with the geometrically most favorable path being selected. This method is quick, but results in an unknown path between the points. This journey is usually not a straight line.

If the work cycle is programmed in this way, the robot can then follow the trajectory from the stored points autonomously and at any speed with a PTP control . The undefined movement between the individual points can be specified by parameters . The speed and acceleration can be selected, and the PTP control with blending can be selected for even movement .

CP: Continuous Path: Here the robot is instructed not only to drive from one point to the other, but also to follow a given path. This ride is i. d. Usually slower than P2P, but a certain path is only left within narrow tolerances. This method is suitable for complex joining processes in which speed is less important than accuracy (e.g. due to obstacles).
