Abstract

A system and method of dynamic virtual collision objects includes a control unit for a medical device. The control unit includes one or more processors and an interface coupling the control unit to the medical device. The control unit is configured to determine a position of a first movable segment of the medical device, a volume occupied by the first movable segment being approximated by one or more first virtual collision objects (VCOs); adjust, based on the position and motion goals for the medical device, one or more properties of the first VCOs; determine, based on the position and the properties, first geometries of the first VCOs; receive second geometries of one or more second VCOs associated with a second segment of a second device; determine relationships between the first VCOs and the second VCOs; and adjust, based on the relationships, a motion plan for the medical device.
