...ANSWER
Answered 2021-Feb-21 at 07:31You can see the description for JSON function here:
- JSON.parse() takes a JSON string and transforms it into a JavaScript object.
- JSON.stringify() takes a JavaScript object and transforms it into a JSON string.
In this case the fetch api always return Response Object. This is just an HTTP response, not the actual JSON. To extract the JSON body content from the response, we use the json() method. And after that you can use newsId.articles to get articles list

QUESTION
Short version is the post title.
Long explanation here.
Recently, I've been working on a rover project, the suspension mechanism for which is rocker-bogie mechanism with a differential bar (not a gearbox) .
I have been working on the simulation task using Gazebo but the problem is URDF does not support closed-loop kinematic chains and the rocker-bogie suspension mechanism actually turns the robot into a closed-loop chain.
Now, since Webots is free too and it actually has a rover model (Sojourner), I'm wondering if it support robots with closed-loop chains.
Thanks
...ANSWER
Answered 2019-Oct-14 at 12:38Yes, Webots supports closed-loop kinematic chains thanks to the SolidReference node which allows you to close the loop at any point. Simple example simulations of close-loop chain include the Stewart platform or even simpler, the pedal racer. The NASA Sojourner robot is a more complex robot, but doesn't include closed-loop chains.
