Hi All,

After loading an URDF/SDF using loadURDF/SDF method in pybullet, how can I get the index of a link by its name in the URDF/SDF.
I see in the documentation that there is getJointInfo method to do this for joints but nothing for links. Any help is appreciated. Thank you.

Cheers,
Shravan

Found an important information that helped solve this issue.
In bullet linkIndex == jointIndex

Using the above, I currently have the following solution below

Code: Select all

_link_name_to_index = {p.getBodyInfo(model_id)[0].decode('UTF-8'):-1,}
        
for _id in range(p.getNumJoints(model_id)):
	_name = p.getJointInfo(model_id, _id)[12].decode('UTF-8')
	_link_name_to_index[_name] = _id
