How to use world as a joint link programmically?
I've been using this SDF to fix linkA to the world, however I am unsure how to do this programmically.
<joint name="base_joint" type="fixed">
<parent>world</parent>
<child>linkA</child>
</joint>
The Joint class functions Load and Attach both take LinkPtr as parameters. How can you replicate the SDF in code? Thanks in advance!
