The larger robots include two human-sized robots (the B21R and a PeopleBot), three Pioneer robots (two of them all-wheel terrain vehicles), Tevbot (a student-built, robotic spider), Eleanor (a pneumatic-driven, larger-than-human pair of robotic arms), and a three-foot radius dodecahedron robotic blimp.


The Department of Geology holds extensive paleontology, mineral, and rock collections for research and teaching. A fully-equipped rock preparation facility, with rock saws, grinding, polishing, crushing, thin section and mineral separation equipment, allows students and faculty to prepare their own samples for petrographic and geochemical analysis. For rock and mineral analysis the department has petrographic microscopes, a Rigaku Ultima IV x-ray diffractometer, an ELTRA Carbon and Sulfur Determinator with TIC module, an inorganic/organic Carbon analyzer, an inductively coupled plasma mass spectrometer, a sedimentology laboratory, a fluid inclusion laboratory, a cathode luminescence facility, and morphometric, Carpenter Microsytems Microsampler and image analysis systems for paleontology. The department also houses a fully equipped paleomagnetic and rock magnetic lab that includes an Agico JR-6A spinner magnetometer, an ASC thermal demagnetizer, a DTECH 2000 alternating field demagnetizer, a 10.0 Tesla pulse magnetometer, an Agico KLY2 automated susceptibility bridge, and a dynamic low-magnetic field cage. Field equipment includes a collection of Brunton compasses, a high-precision surveying total station (theodolite and electronic distance meter), high precision GPS (both handheld and antenna based), high precision magnetic gradiometer, rock drills and ground-penetrating radar.


The Department of Physics has several laboratories for education and research. The two instructional "modern physics" laboratories house oscilloscopes, digital multimeters, power supplies, low-temperature facilities, and a great deal of ancillary equipment commonly found in research laboratories. In addition, the instructional optics laboratory has six dark rooms with interferometers, lasers, and miscellaneous equipment for optics experiments. The instructional nuclear physics laboratory houses a low-temperature gamma detector and computer-based multichannel analyzers for nuclear spectroscopy, alpha particle detection, and positron-electron annihilation detection. The instructional electronics laboratory has fourteen stations equipped with electronic breadboards, function generators, power supplies, oscilloscopes, multimeters, and computers. The Atomic and Optical Physics research laboratory is equipped with three optical tables, two ultrahigh vacuum systems used for cooling and trapping of atomic rubidium, a host of commercial and home built diode laser systems, several YAG pumped dye laser systems, a high vacuum atomic beam system, an electron multiplying ccd camera, and a variety of other supporting equipment. The Solid State Dynamic Nuclear Magnetic Resonance (NMR) research laboratory is equipped with two variable-temperature nitrogen flow systems, three fixed-frequency CPS-1 Spin Lock Pulsed NMR Spectrometers, a Varian 1.2 Tesla water-cooled electromagnet, a Spectro Magnetic 0.4 Tesla air-cooled electromagnet, two data acquisition systems, and ancillary electronics and computers. The Photo-Physics Laboratory houses three optical tables, two Nd:YAG pump lasers, three commercial, tunable dye lasers, two auto-tracking harmonic crystal systems, a differentially pumped vacuum chamber with a supersonic pulsed valve to produce molecular beams, and a time-of-flight mass spectrometer for ion detection. In addition, there are various pieces of equipment for data acquisition and laser energy calibration.


The Department of Psychology provides students with laboratory experience encompassing the wide range of subject matters within the discipline of psychology.

This equipment includes oscilloscopes high gain amplifiers, miniature head stages, and stimulators, The equipment interfaces with computers with advanced software for evaluating electrophysiological data. There is also equipment for the microinjection of pharmacological agents for the evaluation of the role of neurotransmitters in important aspects of behavior. For research in cognition, students have access to a variety of computerized programming equipment. This equipment includes digital video cameras, video editing programs, behavioral coding programs, and statistical analysis programs that are used to analyze the behavior, cognition and emotions of human participants ranging in age from early childhood to older adulthood. The laboratory in Introductory Psychology has equipment for studying sensation and perception, decision-making, language processing, and the psychophysiological correlates of human cognition and emotion.
