Hi. After 7 years of development. This robot works stably. It is currently working for over two years without problems, What we are seeing right now is trades exponentially. This configuration is just to show what the robot is capable of. In any case, this is not recommended by the manufacturer. Those who want to try working with the robot, will get a more relaxed and less dangerous set up. If you have any questions write to us and we will answer any question.
