Adding supervisor node on Webots R2019a

Question

I am very new in Webots simulator as well as in robotics. I am using new open source version of webots. I believes it is not compatible with older versions of webots. I tested some old programs available on GitHub. That doesn't work. In some programs I saw Supervisor node. But I didn't saw any supervisor node on Webots R2019a. How can I add supervisor node on Webots version R2019a?

Answer 1

The Supervisor node was deprecated in Webots R2019a. But it should still be working (thanks to a PROTO mechanism). To create a new supervisor in Webots 2019a, you should create a Robot node and set its supervisor field to TRUE. See the documentation about it here: https://www.cyberbotics.com/doc/reference/supervisor
