# Flexible Line Recovery Robot — Working Claim Set V1.0 ## Legal status These are working technical claims for professional patent-counsel review. They are not legal claims and do not establish novelty, inventive step/non-obviousness, validity or freedom to operate. --- ## Independent apparatus claim — working draft **1.** A system for recovering a disordered flexible line, comprising: a constrained recovery chamber configured to receive the disordered flexible line; a plurality of independently controllable compliant handling modules positioned to interact with the flexible line within the constrained recovery chamber; one or more sensors configured to generate observations of the flexible line and at least one physical response associated with manipulation of the flexible line; and a controller configured to: (a) generate a line-state representation comprising at least geometric information and topological information concerning the flexible line and a physical-state indication; (b) select a manipulation action based at least in part on the line-state representation; (c) execute the selected manipulation action using one or more of the compliant handling modules; (d) verify whether a physical state transition associated with the manipulation action occurred by comparing an expected state change with observed geometry and at least one physical response; (e) commit a new line state only when the physical state transition is verified; and (f) when the physical state transition is not verified, return the system toward a previously verified line state and select an alternative manipulation action for the unresolved line configuration. --- ## Independent method claim — working draft **2.** A computer-implemented method for recovering a disordered flexible line in a constrained recovery environment, comprising: observing the flexible line; generating a line-state representation including geometric and topological information and a physical-state indication; identifying an unresolved crossing, loop or other recovery condition; selecting a manipulation action based on the line-state representation; executing the manipulation action with a compliant handling module; verifying the resulting physical state using observed geometry and at least one physical response; committing the resulting line state only after successful verification; and when verification fails, returning toward a last verified line state and selecting an alternative manipulation action. --- ## Independent control-system claim — working draft **3.** A control system for an automated flexible-line recovery apparatus, comprising: a state estimator configured to maintain a line-state representation; a manipulation planner configured to select actions from the line-state representation; a verification engine configured to compare predicted and observed state transitions using geometry and physical-response information; a checkpoint manager configured to retain a last verified state; and a recovery controller configured, following a failed verification, to initiate a rollback operation and select an alternative manipulation action subject to configured physical constraints. --- ## Dependent claim group — constrained environment **4.** The system of claim 1, wherein the constrained recovery chamber is shallower than a conventional robot-arm work envelope and is configured to limit out-of-plane displacement of the flexible line. **5.** The system of claim 1, wherein the chamber provides a controlled visible recovery field through which the sensors observe the flexible line. **6.** The system of claim 1, wherein the recovery chamber is coupled directly to a downstream organization path. --- ## Dependent claim group — line-state representation **7.** The system of claim 1, wherein the line-state representation includes endpoints and segment relationships. **8.** The system of claim 1, wherein the line-state representation includes crossing candidates. **9.** The system of claim 1, wherein the line-state representation includes loop candidates. **10.** The system of claim 1, wherein the physical-state indication includes a local tension classification or measured tension. **11.** The system of claim 1, wherein the line-state representation includes an ownership association identifying a handling module supporting or controlling a line segment. **12.** The system of claim 1, wherein the line-state representation includes confidence values for one or more estimated state elements. --- ## Dependent claim group — slack-first recovery **13.** The method of claim 2, wherein selecting the manipulation action comprises selecting a slack-creation action when local tension associated with an unresolved crossing or loop exceeds a configured threshold. **14.** The method of claim 13, further comprising reassessing geometry or topology after reducing local tension and before executing a separation action. **15.** The system of claim 1, wherein the controller is configured to inhibit a separation action until a configured local tension condition is satisfied. --- ## Dependent claim group — verification **16.** The system of claim 1, wherein verification uses both geometric information and at least one of tension, contact, motor current, actuator position or motion response. **17.** The method of claim 2, wherein a state transition is rejected when the observed physical response is inconsistent with the predicted response. **18.** The control system of claim 3, wherein the verification engine produces a verification record associated with a state identifier. --- ## Dependent claim group — rollback **19.** The system of claim 1, wherein the controller stores a checkpoint corresponding to a last verified physical state. **20.** The system of claim 1, wherein the controller selects a rollback action from a set including reverse, release, regrasp and transfer actions. **21.** The method of claim 2, wherein a failed verification does not become the committed recovery state. **22.** The control system of claim 3, wherein the recovery controller enters a safe-stop state when rollback is determined to be physically unsafe or infeasible. --- ## Dependent claim group — distributed handling **23.** The system of claim 1, wherein two or more handling modules independently support different portions of the flexible line. **24.** The system of claim 23, wherein a line segment is transferred from a first handling module to a second handling module while the line-state representation is updated to identify the second handling module as the owner or support module. **25.** The method of claim 2, wherein manipulation is performed by a sequence of local module-to-module transfers without requiring a single conventional robot arm to execute the complete recovery sequence. --- ## Dependent claim group — organization **26.** The system of claim 1, further comprising an organization path configured to receive the flexible line after a verified recovery condition is reached. **27.** The method of claim 2, further comprising transferring a verified recovered line into a straightening, routing or coiling operation. **28.** The system of claim 26, wherein transfer to the organization path is controlled as a state transition within the same supervisory state architecture used for recovery. --- ## Dependent claim group — interchangeable handling **29.** The system of claim 1, wherein at least one handling module includes an interchangeable handling cartridge. **30.** The system of claim 29, wherein the interchangeable handling cartridge is selected according to a class of flexible line including cable, rope, strap or hose. **31.** The system of claim 29, wherein the cartridge changes at least one of contact geometry, compliance, friction, gripping profile or permissible force limit. --- ## Dependent claim group — safety **32.** The system of claim 1, further comprising force, tension, position or velocity limits associated with one or more manipulation actions. **33.** The system of claim 1, further comprising a watchdog configured to place the apparatus into a safe state when a control heartbeat or expected actuator response is absent. **34.** The system of claim 1, further comprising an emergency release mechanism configured to release the flexible line independently of the normal recovery sequence. --- ## Dependent claim group — operator intervention **35.** The method of claim 2, further comprising detecting an operator intervention, re-observing the flexible line after the intervention and establishing a new verified state before resuming automated recovery. --- ## Dependent claim group — records **36.** The control system of claim 3, further comprising a run record containing state identifiers, selected actions, verification outcomes and fault or rollback events. --- ## Drafting strategy for counsel The strongest technical story is the integrated combination rather than any single broad element. The working claim family should be tested in at least three directions: 1. apparatus/system; 2. method/control sequence; 3. controller/software architecture. Counsel should determine whether the final claim scope should be narrowed toward the combined relationship between: - constrained recovery environment; - distributed compliant handling; - topology/tension state; - slack-first action selection; - physical-response verification; - verified-state checkpoint; - rollback and alternative action; - controlled organization transition. The claim language must be rewritten as necessary after a formal patent search and jurisdiction-specific legal analysis.
