A couple methods from RigidBody aren't being imported

1

I was trying to access the RigidBody method ```frame_definitions(body)``` after importing the RigidBodyDynamics library, but I was getting an Undefined Variable Error every time. However, ```default_frame(body)```, another method in that...

Symbolic Derivatives with SymPy do not work

As of the latest version, the example is broken. https://github.com/JuliaRobotics/RigidBodyDynamics.jl/blob/master/examples/6.%20Symbolics%20using%20SymPy/6.%20Symbolics%20using%20SymPy.jl Using version 2.2.0 works. The issue is that Quaternion does not support type Sym. I can update later with more...

Support for spring elements

Are spring connections supported? If not, that would be a nice addition. Their action would simply result in a force proportional to the relative displacement of two points. Thanks!

Hi, I came across a strange issue. If I connect a body who's moment of inertia is not expressed at it's center of mass using a `QuaternionFloating` joint the inverse...

I would find it useful to have type restrictions reflected in the method signatures shown in the documentation. When I read ```julia attach!(mechanism, predecessor, successor, joint; joint_pose, successor_pose) ``` I'm...
