 The core unit, which can operate autonomously or telerobotically (via commands sent from the ground), consists of a large incubator, two centrifuges, a microscope, a spectrophotometer (an instrument used to measure the spectrum of light absorbed by a sample), a sample-handling mechanism, and Automatic Temperature-Controlled Stowage (ATCS) to keep small amounts of sample.The manual section consists of the Experiment Preparation Unit (EPU), the BioGloveBox (BGB), and additional Temperature Control Units (TCUs) for storing experiment containers (ECs) and preserving samples.The EC is designed to enclose a variety of biological samples and provide an interface with the other BioLab subsystems, such as power, data, and life support.
