  • Publication number: 20250018557
    Abstract: A feed mechanism for inserting and/or retracting a flexible robotic arm from an area, the feed mechanism including a housing, a passageway extending about a central longitudinal axis through the length thereof, a drive portion and rotational portion, the drive portion not being fixedly connected within the housing and having at least a pair of drive wheels coupled to a drive motor, the drive wheels are connected to a mounting frame with the mounting frame being connected to pivotable linkages with at least one of the linkages being connected to a spring, such that the expansion or contraction of the spring allows the drive wheels to move relative to the longitudinal axis, and the rotational portion being coupled to a motor, the rotational motor having a gear system that connects to the drive portion and causes a rotation of the drive portion about the central longitudinal axis within the housing.

  • Publication number: 20250018579
    Abstract: A system for inserting a flexible robotic arm into a workspace, the system having: a feed mechanism having a housing containing a drive mechanism, the drive mechanism gripping the flexible robotic arm using at least one drive wheel which is coupled to a drive motor, the feed mechanism is provided with at least one force sensor; and a haptic controller coupled to the feed mechanism, the haptic controller having input controller for instructing the drive motor within the feed mechanism to activate in response to the signal from the input controller, and wherein the input controller is provided with haptic feedback to provide an operator an indication of the state of operation of the feed mechanism based on signals output from signals provided by the force sensors.

  • Publication number: 20250020546
    Abstract: A system for inspecting a complex component, the system comprising: a flexible inspection device having a driver for controlling the motion of the flexible inspection device by manipulating the relative positions of a plurality of joints within the device, the flexible device having a sensor on its distal end; a feed mechanism for controlling the insertion or retraction of the flexible device into or from the complex component; a component driver for driving the movement of an aspect of the complex component from at least a first position to a second position; and a computer running a computer program, the computer interfacing with the flexible inspection device, the feed mechanism, and the component driver, so as to link the operation of the flexible inspection device, the feed mechanism and the component driver through a single program.
