The SSL, under funding from NASA's ASTEP (Astrobiology Science and Technology Experiment Program) is working to develop robotic technologies for autonomous undersea sampling.
Autonomous Rendezvous and Docking
Compliance Control for the Ranger Dexterous Manipulator
The Hydrogen Peroxide Portable Life Support System (HyPerPLSS) is a single-fluid PLSS concept, based on hydrogen peroxide.
Joint Angle Measurement System for Teleoperation of a Robotic Manipulator (JAMSTORM).
The Maryland Advanced Research/Simulation suit is a simplified neutral buoyancy spacesuit for use in EVA research.
The Metabolic Workload Measuring System for Space Suits is an advanced space suit research project investigating methods of quantitative analysis of astronaut workload during EVA.
The Morphing Upper Torso is an advanced space suit research project investigating a robotically augmented pressure suit for planetary exploration.
Partial Gravity Simulation using a ballast system.
The Ranger Telerobotic Shuttle Experiment (RTSX) is a space robot designed to perform telerobotic servicing experiments while in the cargo bay of the orbiter.
The Ranger Satellite Servicing System is a dexterous robotic servicing system developed under funding from NASA as part of their Space Telerobotics Program.
The Supplemental Camera and Maneuvering Platform (SCAMP) is a neutral buoyancy robot designed as a flying camera to give ground controllers and astronauts better views of EVA excursions and to inspect worksites in orbit. The SCAMP project currently encompasses two operational vehicles, SCAMP and SCAMP SSV.
The Tool for EVA or Robotic Planetary Sampling
The Visual Positioning System is a sensor system for determining the position of robots in the neutral buoyancy tank.

Undergraduate Projects


The Operational System for Inspection, R esearch, and Instrument Support (OSIRIS) is a remotely operated free-flying camera robot. Designed to fly in air, OSIRIS has full six axis control and can serve as a test platform for several areas of research including attitude control, path planning, inspection tasks, and human-robot interaction. This project was flown on NASA's KC-135 microgravity simulation aircraft in 2004.

Completed Projects


The Advanced EVA Tool project is a research effort to develop more efficient tools for astronauts to use during EVA excursions. This project is a cooperative effort with Goddard Space Flight Center and Johnson Space Center.

The Beam Assembly Teleoperator (BAT) was the first robot developed by the SSL. BAT was designed to build large structures in space. During its lifetime, BAT demonstrated the ability of robots to perform space construction tasks and also to repair satellites, service space hardware, and work in cooperation with astronauts.
The Control Station project is aimed at building better human/robot computer interfaces. A major part of the control station project is to develop the flight and ground control stations for the Ranger Telerobotic Shuttle Experiment.
The Joint Angle/Muscle Signature (JAMS) system is a sensor system that fits inside a spacesuit and measures the angles in the joints of the hand and the electrical activity of the muscles of the forearm. It will allows researchers to measure muscle fatigue during EVA excursions.

The Microgravity Simulation Posture Study was an experiment comparing human reactions in different simulations of weightlessness.
The Multimode Proximity Operations Device (MPOD) is a neutral buoyancy robot that is used to investigate new ways of piloting spacecraft.
The Power-Assisted Glove is a prototype motorized spacesuit glove which will help reduce hand fatigue in astronauts during EVA excursions.
The Ranger Neutral Buoyancy Vehicle (RNBV) is an underwater prototype of a space robot designed to repair satellites and assist astronauts during EVA excursions.
The Test Stand for Upper-body Neuromuscular Adaptive Movement Investigation (TSUNAMI) is a parallel manipulator designed for use with human subjects for the investigation of upper limb motor control and adaptation.
The Three-Dimensional Acoustic Positioning Sytems (3DAPS) provides position information of the robotic vehicles in the NBRF.
