1. A robotic device, comprising:

  • (a) a device body configured to be disposed within a patient;

    (b) an attachment component operably coupled with the device body;

    (c) a connection component operably coupled with the device body, wherein the connection component comprises a tether;

    (d) an external power source operably coupled to the tether;

    (e) a first operational arm comprising;

    (i) a first inner arm segment operably coupled with the device body via a first shoulder joint;

    (ii) a first outer arm segment operably coupled with the first inner arm segment via a first elbow joint; and

    (iii) a first operational component operably coupled with the first outer arm segment;

    (f) a second operational arm comprising;

    (i) a second inner arm segment operably coupled with the device body via a second shoulder joint;

    (ii) a second outer arm segment operably coupled with the second inner arm segment via a second elbow joint; and

    (iii) a second operational component operably coupled with the second outer arm segment, wherein the first and second operational arms are configured such that the first and second operational arms are not positionable within an enclosure of the robotic device;

    (g) at least one actuator disposed within each arm, the at least one actuator operably coupled to the tether and the arm, wherein the actuator is configured to actuate movement of the arm; and

    (h) at least one imaging component operably coupled with the device body, wherein the at least one imaging component is positioned between the first and second operational arms such that the first and second operational arms are viewable by a user via the at least one imaging component during operation of the first and second operational arms.
