Personally, I first learned about such robotic cats. The fact that they perform useful functions and they have some advantages over straining with ordinary "live" cats - is of interest. First of all, they do not require so much care for themselves and this is undoubtedly a plus, especially for the elderly. In addition, those functions that robotic koshla performs for the elderly are simply vital - for example, to remind you to take the medicine.
The main function that any robo-mechanism must perform, whether it is a humanlike robot or koshla is a robot, is executed. That is, in my opinion the main function is to help a person and improve the quality of his life. The robot as a matter of fact takes a part of important duties on itself and perfectly with it consults.
I think that progress is moving in the right direction and soon such homemade robo-pets will be something ordinary. No one will be surprised to have a robot in the house of an ordinary person.
Thank you for the interesting article, I like to observe the development of technologies, including in the robotics industry.
