Abstract: A robotic imaging system includes a body with a head unit, a robotic arm and a coupling plate. A camera is positioned in the head unit and configured to record one or more images of a target site. The camera is operatively connected to one or more handles. A plurality of sensors is configured to transmit sensor data. The sensors include at least one primary sensor configured to detect respective force and/or respective torque applied at the body and at least one auxiliary sensor configured to detect the respective force and/or the respective torque applied at the one or more handles. A controller is configured to receive the sensor data and execute a contact management mode, including determining a contact location of the body with an external object based in part on the sensor data and determining a reverse trajectory for moving the body away from the contact location.

Abstract: A robotic imaging apparatus is disclosed. A robotic imaging apparatus includes a robotic arm, a stereoscopic camera, and a sensor positioned between the robotic arm and the stereoscopic camera. The sensor transmits output data that is indicative of translational and rotational force imparted on the stereoscopic camera by an operator. The robotic imaging apparatus also includes a processor that is configured to determine a movement sequence for the robotic arm based on a current position of the robotic arm and the output data from the sensor and to cause at least one of the joints of the robotic arm to rotate based on the determined movement sequence via one or more motor control signals provided to the at least one joint. The rotation of the at least one joint provides power-assisted movement of the robotic arm based on the detected translational and rotational forces imparted by the operator.

Abstract: A method, instructions for which are executed from a computer-readable medium, calibrates a robotic camera system having a digital camera connected to an end-effector of a serial robot. The end-effector and camera move within a robot motion coordinate frame (“robot frame”). The method includes acquiring, using the camera, a reference image of a target object on an image plane having an optical coordinate frame, and receiving input signals, including a depth measurement and joint position signals. Separate roll and pitch offsets are determined of a target point within the reference image with respect to the robot frame while moving the robot. Offsets are also determined with respect to x, y, and z axes of the robot frame while moving the robot through another motion sequence. The offsets are stored in a transformation matrix, which is used to control the robot during subsequent operation of the camera system.

Abstract: System and method for imaging a target site with a housing assembly having a head unit configured to be at least partially directed towards the target site. An optical coherence tomography (OCT) module and stereoscopic visualization camera are at least partially located in the head unit and configured to obtain a first set and a second of volumetric data of the target site, respectively. A controller is configured to register the first set of volumetric data with the second set of volumetric data to create a third set of registered volumetric data. The third set of registered volumetric data and second set of volumetric data are rendered, via a volumetric render module, to a first and second region. The first region and the second region are overlaid to obtain a composite shared view of the target.
