The teaching pendant, also known as the teaching programmer or teaching box, is a hand-held device for manual operation, program writing, parameter equipment and monitoring of the robot; It is the core component of the robot control system, and is a device used to register and store mechanical motion or processing memory, which is performed by the electronic system or computer system.
Industrial robot teaching is that the programmer selects various teaching methods to "inform" the robot in advance of the action information and operation information, etc., which are mainly divided into three categories:
1. Robot position and attitude information, trajectory and path point information;
2. Information such as the sequence of robot mission actions;
3. Information such as robot action, additional conditions during operation, speed and acceleration of robot action, and information about the content of the operation.
Question 1: Can the teach pendant of different manufacturers be universal?
Answer: No!
The industrial robot is controlled by the controller, and is connected to the teach pendant with buttons and touch screen through a 5-8 meter long cable, which requires that the system, algorithm and software between the teach pendant and the robot must be compatible with each other, so as to form a closed-loop adaptation.
In fact, each enterprise has its own logic programming, different brands of product systems, software will be different, such as the system programming language common C++, Windows, ST language, etc., different brands of products between industrial robots are not communicative.
As a result, different brands of industrial robots cannot use universal teach pendants.
Question 2: Can the teach pendant be used in the same product series?
Answer: Not necessarily.
Every enterprise will have the experience of product iteration, system iteration, software iteration, if the system, software upgrade, different versions of the product, their communication may be incompatible with each other, such as Windows 2010 and Windows 2000 two new and old system products, will present the system incompatible, then the products of different systems will not be able to share the teach pendant.
In addition, there are products produced by the same company, which may also use a variety of operating systems and software, which are generally incompatible with each other.
There is an exception to the general purpose, but it needs to be specially developed by the original factory, but for the user, it will be a big expense, because of the small loss.
Question 3: Is it possible to do without a teach pendant?
Answer: Yes.
The teaching method of industrial robots has direct teaching method, remote control teaching method, direct teaching method and other methods, the teaching box is only a common use method, and can also be completed by other methods, such as directly through the computer input parameters.
Now many special equipment integrated with the Scara robot no longer need a teach pendant, such as the special equipment for CCD detection, the integrated Scara robot is equipped with visual assistance, and the teaching can be completed by the computer.
Q4: Is it possible to control the robot directly with offline programming software?
Answer: Yes.
This type of program is most common in welding lines. In scenarios with many robots such as car production, the power of using the teach pendant to debug one by one will be very low, so the pre-written programs are generally imported into the robot one by one, and then the parameter setting is quickly completed.
Of course, in order to prevent accidents, the teach pendant will also be carried with you.
Question 5: Is it possible to share a teach pendant with multiple robots?
Answer: Yes.
As long as the robot is compatible with each other, then it is possible to use one teach pendant to complete the sharing of multiple devices.
However, from the point of view of management, if the production line presents a problem, then as long as a teach pendant will bring a lot of trouble to the fault investigation, because as long as there is a teach pendant, the parameters of each robot must be queried by the computer, which is very unfavorable to the operation, and if each robot has an independent teaching pendant, then when the fault is investigated, only need to check the parameters in the corresponding teach pendant, which is very convenient and fast.
Otherwise, it will affect the output power of the enterprise, which will be lost due to small losses.

Reducer on the KUKA robot
The most important thing in the human arm is the joints and ligaments, and the most important thing in the robot is in each joint: the reducer. This is a fine power transmission organization, which uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions, and obtains a large torque setting.
