解析：(1).细节理解题。根据第一段中的"robotshavebeenhard,madeofmetal"以及"...hasmanagedtobuildanentirelysoftrobot—onethatdrawsinspirationfromanoctopus."的对比可知,Octobot机器人的特点是它很柔软。

(2).推理判断题。根据第三段第一句"Robotsbuiltforprecise,repetitivemovementsinacontrolledenvironmentdon'tdosowellonroughterrainsorinunpredictableconditions."以及本段内容可知,传统机器人无法在崎岖的地形上很好地运行,此外,由于沉重的金属部件,传统机器人可能会对人体产生伤害,据此可推断出,传统机器人的缺点是他们不能一直表现得很好。

(3).细节理解题。根据倒数第二段中的"Evenifengineersbuildasiliconebody,it'sstillagrandchallengetoconstructflexibleversionsofessentialparts,suchasasourceofpower."可知,即使工程师利用硅酮制造出了软体机器人的身体,但是制作柔韧性强的关键部件仍然面临巨大的挑战,比如动力来源。据此可知,最大的挑战之一是柔韧性强的动力来源。

(4).细节理解题。从文章最后一段中的"Althoughsoftroboticsisstillinitsearlystage,itholdsgreatpromiseforseveralapplications,suchassearchrescueoperationsandexploration..."可知,尽管对软体机器人的开发和研究还处于早期阶段,但它适用于诸如搜索救
