Issue Description

Feature Request

As a end-user, I want to serialize a RobotModel that I created programatically so that I can load it back later from file.


I have a lot of trouble trying to pickle RobotModel, either using pickle or jsonPickle with no success. The decoded object doesn’t function anymore.

I created a little script to check if my returned object still works:

def LoadToolAndCheck(json_path):
    with open(json_path, 'r') as f:
        json_str =
        tool = jsonpickle.decode(json_str, keys=True)

    print (tool.__class__)
    for l in tool.links:
        print (l.__class__, l)

One specific scenario is when I create this RobotModel object in Rhino GH, and then I deserialize it in CPython, it will not function anymore.

Describe the solution you’d like I want a way to serialize RobotModel objects, either by jsonpickle or pickle or a ‘to_data’ type of method. I believe for the consistency with other compas object, a to_data() method is most appropriate.

yes, it should have them. I will work on this soon in the short term.

sorry forgot about this. in my opinion, RobotModel should definitely have from/to_data methods… if @gonzalocasas has the time i would prefer deferring this to him 😃
