两年一度的“挑战杯”全国大学生学术科技竞赛于今年10月下旬在重庆大学举行,这里我们向广大模型爱好者介绍北京航空航天大学参赛并荣获一等奖的项目“鱼类运动仿生研究及其柔体潜艇模型——机器鱼”(见照片)。这条机器鱼是国内首次研制成功的仿生鱼,长0.8米,重约800克,在水中游动时仅有脊背露出水面,动作十分逼真。 The biennial Challenge Cup National Collegiate Academic and Technological Competition was held in Chongqing University in late October this year. Here we introduce the Beijing Aerospace University to the model enthusiasts and win the first prize of the project “Bionic Study of Fish Movement and Its soft-body submarine model - robot fish ”(see photo). This robot fish is the first successful development of bionic fish in China, 0.8 meters long and weighs about 800 grams. When swimming in the water, only the spine out of the water, the action is very realistic.
