    • A system is used for robotically controlling movement of a human-controllable catheter, wherein the catheter has a distal end and at least one position sensor for generating or receiving signals used for determining six dimensions of location and orientation information of the distal end of the catheter. The system uses a robotic control mechanism for holding and manipulating a human-controllable catheter and a computer operatively communicating with the robotic control mechanism for driving the robotic control mechanism to (i) translationally move a distal end of a human-controllable catheter in a vicinity of a target, (ii) deflect a distal end of a human-controllable catheter, and (iii) rotate a human-controllable catheter in a vicinity of a target. The computer determines roll of a human-controllable catheter using six dimensions of location and orientation information based on signals generated or received from at least one position sensor on a human-controllable catheter.

    • A calibration apparatus includes a fixture, which is coupled to accept a probe so that a distal tip of the probe presses against a point in the fixture and produces first measurements indicative of a deformation of the distal tip relative to a distal end of the probe, in response to pressure exerted on the distal tip. A sensing device is coupled to the fixture and is configured to produce second measurements of a mechanical force exerted by the distal tip against the point. A calibration processor is configured to receive the first measurements from the probe, to receive the second measurements from the sensing device and to compute, based on the first and second measurements, one or more calibration coefficients for assessing the pressure as a function of the first measurements.
