Abstract

The authors describe the Ranger robotic system and its autonomous hazard control system, which is designed to meet the stringent criteria imposed on space shuttle payloads. This article summarizes tests performed to date, particularly regarding the safety system, and describes ongoing work to apply Ranger technologies with higher autonomy levels to new robotic systems, including an ambitious project to autonomously collect geologic and biologic samples around hydrothermal vents under the Arctic icecap.
