ISS Science for Everyone

Science Objectives for Everyone

Robonaut was developed under the Space Act Agreement between NASA and General Motors (GM) and was launched to the ISS on STS-133.  Robonaut is a dexterous humanoid robot designed with the versatility and dexterity to manipulate hardware, exhibit greater endurance than humans and react safely when bumped or interacted with in a way that was not expected.  Robonaut is currently deployed inside the ISS, however, future project goals include mobility in both inside the ISS and outside the ISS in the Extravehicular Environment.  The Robonaut Tele-operations System is an additional control method, beyond ground control, which involves Robonaut mimicking crewmember motions via gloves, a vest and a 3D visor.

    Experiment Description

    Research Overview

    • The Robonaut operational goals demonstrate the capabilities of humanoid robotic technology on the International Space Station (ISS).  Current research involves activities inside the ISS, but future project goals are to demonstrate humanoid robotic capabilities outside the ISS in the Extravehicular Environment.
    • The research being performed could help save crew time by offloading time consuming tasks both inside and outside the space station.  Robonaut could also help reduce human crewmember exposure to dangerous environments by providing a robotic option for investigation or action.  
    • Robonaut technology could evolve into other future robotic missions and other space exploration platforms.

    Description

    Robonaut not only looks like a human, but it also is designed to work like one. With human-like hands and arms, Robonaut is able to use the same tools station crewmembers use. In the future, the greatest benefits of humanoid robots in space may be as assistants for astronauts during spacewalks.

    Robonaut is comprised of a robotic torso with a rotating waist, arms, a head with two high image cameras for eyes and a power pack (backpack). Robonaut is connected to a support stanchion (vertical post or rod) at the waist via an adapter. The stanchion interfaces to the International Space Station (ISS) structure via a base plate and use of the seat track system. The Robonaut Task Board has dummy (non-ISS interfaced) switches that Robonaut can interact with via ground or local ISS commanding.

    Robonaut activities include commanding to perform free space joint manipulation and interface with the task board where it performs simple functions such as flipping switches, removing dust covers and installing handrails. Upon successful completion of Robonaut Task Board experiments, operations will expand to include simple ISS Intravehicular Activity (IVA) tasks within a contained worksite area. During these initial operations, Robonaut is involved with education and public outreach activities demonstrations.

    As each session is successfully completed and operational confidence concerning Robonaut’s capabilities in microgravity are proven, Robonaut will be scheduled for more complex activities. Robonaut’s growth may be supported with hardware and/or software upgrades in future increments.

    The hardware required to perform tele-operation of the robot is the Robonaut Tele-operation System (RTS). The RTS consists of hardware the operator will don which includes a 3D visor, vest and gloves.  These hardware items worn by the operator contains specialized sensors capable of detecting the motion of the operator by mounting a tracking bar.  These sensors transmit the operator movements to a computer that works through the existing Robonaut control software to drive the robot in fashion that mimics the motion of the operator.  Feedback from the robot is in the form of left/right video cameras from Robonaut that feed direct video to a video display helmet that is worn by the operator.

    Applications

    Space Applications

    Robonaut is an endeavor between the National Aeronautics and Space Administration (NASA) and General Motors (GM) to improve robotic technology and capabilities for future space exploration platforms.

    Earth Applications

    General Motors plan to use technologies from Robonaut in future advanced vehicle safety systems and manufacturing plant applications. Robonaut validates manufacturing technologies that will improve the health and safety of GM team members at manufacturing plants throughout the world.

    Operations

    Operational Requirements

    Robonaut is commanded via remote guidance control and success in each research operation is determined by the ground operators based on observations of the Robonaut performance recorded via cabin video and by Robonaut telemetry received on the ground. Each session detailed below can be repeated multiple times to obtain the greatest insight to Robonaut operations in the 0 g (zero gravity) environment and remote guidance.  Robonaut can also be operated using Tele-Operation equipment which involved on-orbit crewmember donning a vest, gloves and 3D visor to manipulate the movements of Robonaut.

    Robonaut is confined to operations in the ISS's Destiny Laboratory. However, future enhancements and modifications may allow it to move more freely throughout the station's interior and eventually the exterior as well.

    Operational Protocols

    Robonaut operates via ground commanding with little interaction by the crewmembers. The exception to this is during Robonaut Tele-Operation (RTS) sessions.  For RTS sessions, crewmembers don a 3D visor, gloves and a vest and Robonaut will mimic their motion.
