Capabilities and limitations of Lead through methods
During this programming method, the traveling of robots is based on the desired movements, and it is stored in the external controller memory.
There are two modes of a control system in this method such as a run mode and teach mode. The program is taught in the teach mode, and it is executed in the run mode.
The leadthrough programming method can be done by two methods namely: Powered Leadthrough Method
Manual Leadthrough Method
Powered Leadthrough Method:
The powered lead through is the common programming method in the industries.
A teach pendant is incorporated in this method for controlling the motors available in the joints. It is also used to operate the robot wrist and arm through a sequence of points.
The playback of an operation is done by recording these points. The control of complex geometric moves is difficult to perform in the teach pendant. As a result, this method is good for point to point movements.
Some of the key applications are spot welding, machine loading & unloading, and part transfer process.
Manual Leadthrough Method:
In this method, the robot‘s end effectors desired movements.
Sometimes, it may be difficult to move large robot arm manually. To get rid of it a teach button is implemented in the wrist for special programming.
The manual leadthrough method is also known as Walk Through method. It is mainly used to perform continuous path movements. This method is best for spray painting and arc welding operations.
Lead through programming is not readily compatible with modern computer based technology.
Robot cannot be used in production, while it is being programmed.
