日本兵库县立姬路工业大学长谷川素有教授领导的研究小组最近研制出了一种救灾用机器人。这种机器人可像尺摸一样屈伸爬行。由5个长立方体连接而成，每个立方体长30厘米、宽8厘米、高5厘米。它以电池为动力，能屈伸地向前行进，最大步幅为15厘米。每秒钟前进6厘米。其“头部” A research team led by Hasegawa, a professor at Himeji University of Technology in Hyogo, Japan, recently developed a robot for disaster relief. This robot can stretch and crawl like a ruler. Consists of five long cubes, each cube 30 cm long, 8 cm wide and 5 cm high. It is battery-powered, able to flexion and forward to the maximum pace of 15 cm. Move forward 6 centimeters per second. Its “head”
