This hardware have made the stair cleaning robot smaller and more multifunctional.</p> <ul> <li>Climbing stairs</li> <li>Cleaning treads (horizontal surface of stairs)</li> <li>Cleaning risers (vertical surface of the stairs)</li> <li>Cleaning stair nosings (the front edge of the treads)</li> <li>Removing obstacles on the treads</li> </ul> <hr> <h2 id="videos">Videos</h2> <h3 id="after-octover-2023">After Octover 2023</h3> <h4 id="climbing-stairs">Climbing stairs</h4> <div style="position:relative;width:50%;padding:calc(1920/1080*50%) 0 0;"> <iframe src="https://drive.google.com/file/d/1NlUUa391uk4GZgdm9Ontyfvl0OxsT59I/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <h4 id="cleaning-treads-horizontal-plane-of-staircase">Cleaning treads (horizontal plane of staircase)</h4> <div style="position:relative;width:100%;padding:calc(1080/1920*100%) 0 0;"> <iframe src="https://drive.google.com/file/d/16KG2L9xwjnBxJ0OJ2Lvb6IHuoHwHaesu/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <h4 id="cleaning-risers-vertical-surface-of-the-staircase">Cleaning risers (vertical surface of the staircase)</h4> <div style="position:relative;width:100%;padding:calc(1080/1920*100%) 0 0;"> <iframe src="https://drive.google.com/file/d/1NHp5Y9VlxCiFzUJLeRYt-i952AGPMc_q/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <h4 id="removing-obstacles-on-the-treads">Removing obstacles on the treads</h4> <div style="position:relative;width:100%;padding:calc(1080/1920*100%) 0 0;"> <iframe src="https://drive.google.com/file/d/1T_iKH_q0DX1k16hofgpMJSSRWDxOYz4L/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <h4 id="the-experiment-integrating-the-above-four-tasks">The experiment integrating the above four tasks</h4> <div style="position:relative;width:100%;padding:calc(1080/1920*100%) 0 0;"> <iframe src="https://drive.google.com/file/d/10i1daTKZpplEp87OPRfj4WvSAdljccG2/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <h4 id="cleaning-stair-nosings-the-front-edge-of-the-treads">Cleaning stair nosings (the front edge of the treads)</h4> <div style="position:relative;width:100%;padding:calc(1080/1920*100%) 0 0;"> <iframe src="https://drive.google.com/file/d/1_tHtPgy1not-PuW_Ic6F4hRjT219zH5p/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <h3 id="before-octover-2023">Before Octover 2023</h3> <h4 id="climbing-stairs-1">Climbing stairs</h4> <div style="position:relative;width:100%;padding:calc(1080/1920*100%) 0 0;"> <iframe src="https://drive.google.com/file/d/1cgdM2cSQoJetmsZ4IHxL5I1055h12qhj/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <h4 id="cleaning-theads">Cleaning theads</h4> <div style="position:relative;width:100%;padding:calc(1080/1920*100%) 0 0;"> <iframe src="https://drive.google.com/file/d/1f4QlHc2dbzflcGIeVt7q-pspSoLEcNrE/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <h4 id="cleaning-risers">Cleaning risers</h4> <div style="position:relative;width:100%;padding:calc(1080/1920*100%) 0 0;"> <iframe src="https://drive.google.com/file/d/14yxNx71KlIHIbL16XHMghS3viCnpyT-x/preview" allow="autoplay" frameborder="0" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe> </div> <hr> <h2 id="research-poster-in-japanese">Research poster (in Japanese)</h2> <div class="gallery-grid"> <div class="gallery-item gallery-item--medium"> <a data-fancybox="gallery-stairs-cleaning" href="https://www.robo.lab.uec.ac.jp/media/albums/stairs-cleaning/SI2023.PNG" > <img src="https://www.robo.lab.uec.ac.jp/media/albums/stairs-cleaning/SI2023_huc50a596c99770da3468982c5784c2e6f_7825316_750x750_fit_q75_h2_lanczos_3.webp" loading="lazy" alt="SI2023.PNG" width="750" height="531"> </a> </div> </div> <h2 id="related-works-in-japanese">Related works (in Japanese)</h2> <ol> <li> <p>保母 諒太朗, 工藤 俊亮, 木村 航平. 小型階段清掃ロボットにおける踏板・蹴込板の全面拭き掃除とマニピュレータによる障害物除去. 第42回日本ロボット学会学術講演会講演論文集, 1D1-06, 2024.</p> </li> <li> <p>保母 諒太朗, 工藤 俊亮, 木村 航平. 踏板・蹴込板の清掃を行う階段登攀型小型ロボット. 第24回SICEシステムインテグレーション部門講演会講演概要集. 2023. 3G5-02</p> </li> </ol>
