Robotic Arm of Rover 1

JPL engineers examine the robotic arm of Mars Exploration Rover 1. The arm is modeled after a human arm, complete with joints, and holds four devices on its end: the Rock Abrasion Tool which can grind into Martian rocks, a microscopic imager, and two spectrometers for elemental and iron-mineral identification.
