A model built in code has no kinematics file behind it, so ModelToProto returned an error and KinematicModelToProtobuf sent an empty response. The frames are now written out the way a file would describe them, static frames as links with their geometries, rotational and translational frames as joints with their limits, mimic mappings as mimic joints, and the existing converters take it from there. A pose frame has no file form and still refuses, and a model with no frames keeps sending nothing, since a message with no links does not parse.

Third rdk piece of RSDK-14233, the Enhanced Arm Kinematics API, for ticket RSDK-14772. Follows #6655, which has merged, and is based on main.
Changes
KinematicModelmessage like a file backed one.ModelToProtoused to return an error for it andKinematicModelToProtobufsent an empty response. The frames are now written out the way a file would describe them and the existing converters take it from there, so a frame built model servesmodeland the synthesized SVA bytes both.NewPoseorCompose.Notes
New2DMobileModelFrameis the one frame built model in tree. The gantry plus arm plus gripper chain a caller can build from the frame system withFrameSystemSubsetandNewModelis the same shape, so it converts too.ModelConfig()still returns nil for a frame built model. The message is the way to such a model, throughModelToProto, and nothing that reads the configuration changes behavior here.Testing
