First, the inspection robot platform and system model are constructed. An improved heuristic function that incorporates target weight information is proposed based on the A* global path planning algorithm. Additionally, redundant nodes are eliminated, and the path is smoothed using the Floyd algorithm and B-spline curves. Second, the global path planning A* algorithm and the local path planning DWA algorithm are fused. The dynamic path planning is carried out by setting the key node information of the global path extracted from the improved A* algorithm as the local target point of the DWA algorithm. On this basis, a grid map is established to simulate and analyze the proposed path planning algorithm. Finally, the autonomous path planning and walking experiment of inspection robot in simulated roadway environment are carried out. The results show that the hybrid path planning method based on improved A* algorithm and DWA algorithm proposed in this paper is more efficient and safer, which can meet the motion requirements of inspection robot in coal mine roadway.<\/jats:p>","DOI":"10.1017\/s0263574725000037","type":"journal-article","created":{"date-parts":[[2025,1,30]],"date-time":"2025-01-30T04:09:27Z","timestamp":1738210167000},"page":"887-908","source":"Crossref","is-referenced-by-count":11,"title":["Research on hybrid path planning of underground degraded environment inspection robot based on improved A* algorithm and DWA algorithm"],"prefix":"10.1017","volume":"43","author":[{"given":"Congcong","family":"Gu","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2801-7969","authenticated-orcid":false,"given":"Songyong","family":"Liu","sequence":"additional","affiliation":[]},{"given":"Hongsheng","family":"Li","sequence":"additional","affiliation":[]},{"given":"Kewen","family":"Yuan","sequence":"additional","affiliation":[]},{"given":"Wenjiie","family":"Bao","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2025,1,30]]},"reference":[{"key":"S0263574725000037_ref18","doi-asserted-by":"publisher","DOI":"10.3390\/electronics12102178"},{"key":"S0263574725000037_ref11","doi-asserted-by":"publisher","DOI":"10.1109\/TEVC.2019.2911736"},{"key":"S0263574725000037_ref5","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2022.3163794"},{"key":"S0263574725000037_ref17","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2024.3367769"},{"key":"S0263574725000037_ref9","doi-asserted-by":"publisher","DOI":"10.1017\/S0263574720000454"},{"key":"S0263574725000037_ref15","doi-asserted-by":"publisher","DOI":"10.1186\/s10033-023-00881-x"},{"key":"S0263574725000037_ref3","doi-asserted-by":"publisher","DOI":"10.1017\/S0263574724000316"},{"key":"S0263574725000037_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.robot.2023.104430"},{"key":"S0263574725000037_ref26","doi-asserted-by":"publisher","DOI":"10.1017\/S0263574723001613"},{"key":"S0263574725000037_ref20","doi-asserted-by":"publisher","DOI":"10.1007\/s10514-016-9597-6"},{"key":"S0263574725000037_ref14","doi-asserted-by":"publisher","DOI":"10.3390\/s23084102"},{"key":"S0263574725000037_ref6","doi-asserted-by":"publisher","DOI":"10.1017\/S0263574724000511"},{"key":"S0263574725000037_ref28","doi-asserted-by":"publisher","DOI":"10.1017\/S0263574714000496"},{"key":"S0263574725000037_ref24","first-page":"4552","article-title":"Mobile robot path planning based on kinematically constrained A-star algorithm and DWA fusion algorithm","volume":"11","author":"Liu","year":"2023","journal-title":"Mathematics -Basel"},{"key":"S0263574725000037_ref8","doi-asserted-by":"publisher","DOI":"10.3390\/jmse11051060"},{"key":"S0263574725000037_ref12","doi-asserted-by":"publisher","DOI":"10.3390\/w16030486"},{"key":"S0263574725000037_ref10","doi-asserted-by":"publisher","DOI":"10.4271\/02-16-04-0022"},{"key":"S0263574725000037_ref7","doi-asserted-by":"publisher","DOI":"10.1186\/s10033-020-00491-x"},{"key":"S0263574725000037_ref2","doi-asserted-by":"publisher","DOI":"10.1017\/S0263574720001253"},{"key":"S0263574725000037_ref1","doi-asserted-by":"publisher","DOI":"10.1109\/TPWRD.2009.2035427"},{"key":"S0263574725000037_ref25","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/185383"},{"key":"S0263574725000037_ref4","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2022.3186368"},{"key":"S0263574725000037_ref13","doi-asserted-by":"publisher","DOI":"10.1109\/TRO.2005.847599"},{"key":"S0263574725000037_ref16","doi-asserted-by":"publisher","DOI":"10.1109\/TII.2023.3346993"},{"key":"S0263574725000037_ref30","article-title":"Investigation on the optimization strategy of DWA algorithm for path planning of the USVs with the consideration of environmental factors","author":"Liu","year":"2024","journal-title":"Int.
