The aim of this study was to develop a stable controller for a mobile robot utilizing BCO in the fuzzy controller and to determine the best membership functions (MFs) in a type-1 fuzzy logic system (T1FLS) for control. Another objective was to use an SIT2FLS to find the best \u03b1 and \u03b2 parameters for BCO to enhance the robot trajectory, which was evaluated through an analysis of the mean squared errors. Three types of perturbations were analyzed and simulated. The performance of the SIT2FLS-FBCO was evaluated and compared to that of the T1FLS-FBCO. In addition, a comparative study was performed to demonstrate that the improved BCO works well when there are disturbances affecting the controller. Finally, it was compared with the Mamdani approach, and an FBCO with an interval type-3 FLS was also developed.<\/jats:p>","DOI":"10.3390\/sym17050789","type":"journal-article","created":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T06:54:28Z","timestamp":1747724068000},"page":"789","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["An Improved Bee Colony Optimization Algorithm Using a Sugeno\u2013Takagi Interval Type-2 Fuzzy Logic System for the Optimal Design of Stable Autonomous Mobile Robot Controllers"],"prefix":"10.3390","volume":"17","author":[{"given":"Leticia","family":"Amador-Angulo","sequence":"first","affiliation":[{"name":"Division of Graduate Studies and Research, Tijuana Institute of Technology, TecNM, Tijuana 22379, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5798-1426","authenticated-orcid":false,"given":"Patricia","family":"Melin","sequence":"additional","affiliation":[{"name":"Division of Graduate Studies and Research, Tijuana Institute of Technology, TecNM, Tijuana 22379, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7385-5689","authenticated-orcid":false,"given":"Oscar","family":"Castillo","sequence":"additional","affiliation":[{"name":"Division of Graduate Studies and Research, Tijuana Institute of Technology, TecNM, Tijuana 22379, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,20]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Designing Pitch Angle Compensator for an UAV and Robustification it with Bee Colony Optimization Algorithm","volume":"8","author":"Alizadeh","year":"2024","journal-title":"Technol.
