Abstract
Continuum robots have become more popular recently due to their scalable dexterity and mobility. However, they may suffer from issues like insufficient stiffness because they are designed to promote their flexibility. To address this issue and further improve their performance in all different application scenarios, stiffness flexibility is essential for this type of robot. Therefore, it is necessary to integrate stiffening techniques into both their mechanical structure and actuation approaches when developing continuum robots. To this end, it is crucial to explore how different stiffening approaches can be applied to various types of continuum robots across diverse applications. The primary goal of this survey paper is to provide a comprehensive review of the state-of-the-art research on stiffening techniques for continuum robots over the last two decades. We thoroughly analyse key techniques related to stiffness tunability mechanisms and stiffening methods. Additionally, we categorise these stiffening approaches on the basis of their properties and seek to understand the factors that limit their performance. This survey paper aims to assist robotic engineers in selecting appropriate stiffening techniques when designing continuum robots and serve as a basis for developing potential next-generation stiffening mechanisms.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
