Abstract
A system comprises a robotic manipulator for control of motion of a medical tool. The robotic manipulator including a joint and a link connected to the joint. The link is configured to connect to the medical tool. A processing unit of the system is configured to receive first data from an encoder of the joint. A first tool tip estimate of a first parameter of a tool tip coupled at a distal end of the medical tool is generated using the first data. The first parameter of the tool tip is a position or a velocity of the tool tip. Second data is received from a sensor system located at a sensor portion of the link or the medical tool. The joint is controlled based on a first difference between the first tool tip estimate and a second tool tip estimate generated using the first and second data.
