To fully exploit their advantages, it is crucial to develop an effective, accurate and robust control system for them. However, research on continuum robot control is still in its infancy and there are many problems remaining unsolved in this field. In particular, this paper focuses on the task-space behavior and the generic control of heterogeneous continuum robots. First, a controller is proposed to achieve the kinematic motion control and visual servoing of continuum robots with predefined task-space behavior. The predefined behavior is twofold: prescribed task-space error and predefined convergence time. Then, the proposed controller is integrated with a velocity-level kinematic mapping estimator to obtain a model-free control system, which is applicable to heterogeneous continuum robots. Furthermore, a re-adjustable performance function is proposed to ensure the effectiveness and robustness of the proposed control system in the presence of external disturbance. Finally, extensive simulations and experiments are performed based on heterogeneous continuum robots, including the cable-driven continuum robot, the parallel continuum robot, the concentric-tube robot, the flexible endoscope, and the pneumatic continuum robot. Our results demonstrate that the task-space error of heterogeneous continuum robots complies with the prescribed boundaries and converges to steady state in predefined time, which reveals the efficacy of the proposed control method.<\/jats:p>","DOI":"10.1177\/02783649241259138","type":"journal-article","created":{"date-parts":[[2024,6,21]],"date-time":"2024-06-21T08:50:16Z","timestamp":1718959816000},"page":"65-95","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Behavior-predefined adaptive control for heterogeneous continuum robots"],"prefix":"10.1177","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0710-6409","authenticated-orcid":false,"given":"Ning","family":"Tan","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering, Sun Yat-sen University, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6310-514X","authenticated-orcid":false,"given":"Peng","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Sun Yat-sen University, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0214-4932","authenticated-orcid":false,"given":"Xin","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Sun Yat-sen University, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0359-7810","authenticated-orcid":false,"given":"Kai","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Sun Yat-sen University, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,6,21]]},"reference":[{"key":"bibr1-02783649241259138","doi-asserted-by":"publisher","DOI":"10.1007\/s10846-017-0734-z"},{"key":"bibr2-02783649241259138","doi-asserted-by":"publisher","DOI":"10.1177\/02783649231202548"},{"key":"bibr3-02783649241259138","doi-asserted-by":"publisher","DOI":"10.1016\/j.gmod.2011.05.003"},{"key":"bibr4-02783649241259138","doi-asserted-by":"publisher","DOI":"10.1109\/LCSYS.2022.3206211"},{"key":"bibr5-02783649241259138","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2008.929402"},{"key":"bibr6-02783649241259138","doi-asserted-by":"crossref","unstructured":"Bedell C, Lock J, Gosline A, et al.
