In 1993, eight volcanologists were killed in two separate events while sampling and monitoring volcanoes. The use of robotic explorers, such as Dante II, opens a new era in field techniques by enabling scientists to remotely conduct research and exploration. Dante II is an industrial robot that was developed by NASA in help by a team from the University of Carnegie in the USA. The robot was produced to carry out exploration inside a live volcano.
Dante II had an aim in 1994, when it was sent to Mt Spurr (Alaska) to conduct an exploration of the volcano. It trekked over crater walls which were deep, but was successful due to its steel frame. Its project up in the mountain was to investigate and bring footage of the surrounding, and in saying so was triumphant. It was able to gather gas and water samples which was sent back for scientists to analyse.
NASA’s intention with the project was to examine robot exploration which may be needed for future Space Missions.

Dante 2 had a steel frame which enhanced its capabilities of rappelling any incline, it was 10 foot long and 8 foot wide and weighed 1700 lbs. It had 8 cameras which allowed it to capture footage of its surroundings. Using its tether cable anchored at the crater rim, Dante II is able to descend down to gather and analyze high temperature gasses from the crater floor. Also connected to the tether cable is a generator and a satellite dish. Via satellite the robot is able to send visual information and data is able to recieve instructions from human operators, hence achieve their goals. Dante is unique as it relies on its sensors to direct it over dangerous and steep cliffs by using a laser which scans for range to unleash its grapple to allow it to climb.
