  1. Fig. 1.

    Robots now roam the surface of a distant planet, exercising increasing levels of autonomy. (A) A MER vehicle leaving the lander platform to begin its exploration of Mars.

This image was taken by Opportunity's panoramic camera on sol 1167 (6 May 2007). It is presented in false color to accentuate differences in surface materials. [Image credit: NASA/JPL/Cornell]

  2. Fig. 2.

    (A) An underwater glider on the deck of a boat, ready for deployment. Gliders can make simple measurements of ocean properties such as temperature and salinity for months at a time, traveling at a speed of about 25 cm/s. (B) A Dorado AUV, capable of carrying complex payloads such as mapping sonar and comprehensive suites for analyzing the physical, chemical, and biological properties of seawater at speeds of 1.5 m/s. This image shows the AUV after recovery by the U.S. Coast Guard cutter Healy, in the icepack north of Svalbard. (C) A docking station with a Dorado vehicle captured in the docking cone, shown in testing before deployment. This device was connected to a cabled observatory, allowing Internet connectivity with the vehicle and the charging of vehicle batteries (46).

  3. Fig. 3.

    A three-dimensional image of the interaction of physical and biological processes, as mapped by an Odyssey AUV off the coast of California (52). The green volumes show a phytoplankton layer, detected by its chlorophyll fluorescence. The underlying cyan surface shows deflection of the constant-density surface by an internal wave, interrupting the phytoplankton layer. To accomplish this survey, the AUV moved in a sawtooth pattern across the survey area while profiling vertically. The volume shown is 6.5 by 2.5 km in horizontal extent and 23 m in depth.
