從無人搬運車原理延伸之競賽項目，競賽焦點除了相撲車自主移動之外，另一個看點則是車體碰撞的刺激感，這部分大大考驗選手於程式編輯之外，還要兼顧車體組成的空間結構設計。競賽隊伍由1-3名成員組成，每隊使用一台相撲機器人與另一隊對戰形式作戰，限定時間內將對方的相撲機器人推場外即為勝方，競賽車體限定使塑膠積木，且參賽相撲車需為全自動相撲車，競賽開始至結束均不可使用無線通訊或遙控器操控參賽相撲車。

2023 TIRT機器人國際賽- 高雄挑戰賽

協辦單位：金屬工業研究發展中心、高雄大學、台灣嵌入式暨單晶片系統發展協會、 睿揚創新科技、愛尚科技

＊參與2023TIRT機器人國際賽-高雄挑戰賽之得獎隊伍，將獲頒高雄市教育局核發之獎狀。

Derived from the principle of unmanned transport vehicles, this competition extends its focus beyond autonomous movement to include the thrilling aspect of vehicle collisions. This aspect significantly tests the participants' skills in not only programming but also spatial structural design of the vehicle body. Each competition team, consisting of 1-3 members, engages in a battle format against another team using one sumo robot. The objective is to push the opponent's sumo robot out of the designated area within the specified time limit to claim victory. The competition restricts the construction of the robot body to plastic building blocks. Furthermore, the participating sumo robots must be fully automated, and the use of wireless communication or remote controllers to control the robots is strictly prohibited from the beginning to the end of the competition.
