1994年7月底到8月中旬,美国卡内基·梅隆大学研制的丹蒂Ⅱ号机器人,在距安克雷奇145公里的斯珀火山进行了一次探险活动。丹蒂Ⅱ号是一个八条腿的蜘蛛形机器人,它高3米,宽2.5米,在平面上的行走速度为0.1米/秒,在斜面上的行走速度要慢得多。它比它的前身丹蒂号要结实得多。1993年1月,丹蒂号在探测南极的埃里伯斯活火山时,只下行了7米就因通信用的光缆断裂而失败了。 卡内基·梅隆大学、航天局和阿拉斯加火山观测站的科学家们通力合作,将机器人送入火山口中。科学家们希望能获取火山口底部的化学及温度特征数据,并拍摄火山口内部的高分辨率图像。设在安克雷奇的指挥中心控制机器人的一举一动,旧金山以南65公里的埃姆斯研究中心的科学家们通过卫星对它加以监视。机器人爬到了198米的深度,到达火山喷气孔区域,它随身携带的3个传感器采集了气体样
From the end of July to the middle of August 1994, the Dante II robot developed by the Carnegie Mellon University in the United States conducted an expedition in the Sperling volcano, 145 kilometers from Anchorage. Dante II is an eight-legged spider robot that is 3 meters high and 2.5 meters wide. It travels at a speed of 0.1 m / s on a flat surface and travels much more slowly on a ramp. It is much stronger than its predecessor, the Dante number. In January 1993, while Dante was detecting an active volcano in the South of the island of Essex, only 7 meters down on the failure of the cable for communications broke. Scientists from Carnegie Mellon University, NASA and the Alaska Volcano Observatory worked together to send the robot into the crater. Scientists hope to get the chemical and temperature characteristics of the bottom of the crater and shoot high-resolution images inside the crater. The command center in Anchorage controls the robot’s movements, and scientists at the Ames Research Center, 65 kilometers south of San Francisco, monitor it via satellite. The robot climbed to a depth of 198 meters and reached the volcanic jet hole area, and the 3 sensors it carried took the gas-like
