2. About Dante ll  Carnegie Mellon The Robotics Institute created a tethered robot that walked and explored Mt.Spurr in Aleutian Range, Alaska.  The scientists used satellite and Internet connections to control and move the walking robot.

3. More on Dante ll  Dante 2 was built to explore volcanoes  It explored Mt. Spurr on July of 1994.  Dante 2 was the evolution of the Dante robot.

4. NASAS Goals  NASA's goals with this project were to test and demonstrate robot exploration, communications and computer technologies which was needed for the space exploration missions.

5. Abilities  This robot has eight legs.  Four of them in the inner frame lift objects. Two are used to walk and the other two are to support the robot.  Using its tether cable anchored at the crater rim, Dante II is able to descend down crater walls to gather and analyze high temperature gasses from the crater floor.

6. Why it failed  Its mission is to collect data from a harsh environment similar to what we might find on another planet. The mission fails when, after a short 20 foot decent, Dante's tether snaps dropping it into the crater.

7. New era  The use of robotic explorers, such as Dante II, opened a new era in the of field techniques by enabling scientists to remotely conduct research and exploration.  Dante II saves volcanologists from having to enter the craters of active volcanoes. It also shows the technology necessary for a robot to explore the surface of the moon or planets.
