簡介
龍行者（英語：Dragon Runner）是一種為城鎮戰組裝的軍用機器人。
重量9磅(4公斤)，算是輕巧能放進海軍背包攜帶。最初的計畫是由海軍陸戰隊聯合卡內基美隆大學投入資金。機器人於卡內基美隆大學進行設計，當時電子工程學與熱塑性外殼皆已開發，並由Automatika公司進行裝配。
機器人有四個輪子，長15英吋（38厘米），不到1英呎寬，以及高5英吋(13厘米)。機器人相當耐用，還能丟過圍牆，在樓梯井爬上爬下，從一輛每小時45哩（每小時70公里)的交通工具，或者甚至從一個三樓高度的窗戶。It does not matter how it lands because neither side is the right side up. However, it was not designed to drive up or down stairs on its own. Instead, Dragon Runner was designed so that it could be carried up the stairway.
套用
龍行者是為因應極危險區域或士兵難以接近的地方而被設計出的，尤其是在城市環境裡。龍行者的前懸掛裝置，tilting camera provides a video feed that is relayed back to its master controller by a wireless modem. It can save lives by providing soldiers with a view around corners and other obstructions that prevent them from seeing hidden enemies.
龍行者能在三種不同模式下運作：
疾馳模式：龍行者於四處各處疾馳，並將影像傳回給操控者。警戒模式：龍行者於原地保持靜止不動，使用麥克風與能偵測可達30英尺（9米）距離動靜的感測器。假如它偵測出一些狀況，將發動警報給操控者。監視模式：龍行者於原地保持靜止不動，並陸續將影像傳回操控者。
修正包含flippers that enable it to climb stairs and treads that can all be snapped on quickly and easily in the field by a soldier with no tools.
2010年1月，under a contract worth £12米 with QinetiQ英國, around 龍行者were ordered by the British army to improve the ability of bomb disposal experts to find and deactivate improvised explosive devices on the front line in 阿富汗. The first in use were then already proving its worth against the threat of 路邊炸彈。
