BB.Error.Kinematics.UnknownLink exception (bb v0.27.0)

Copy Markdown View Source

Link not found in robot topology.

Returned when a lookup names a link the robot does not have.

:role says which parameter was at fault, so a lookup taking both ends of a chain — BB.Robot.path_between/3 — can report an unknown source as a source rather than misattributing it to the target. It is nil for lookups that take only one link.
