Robonaut (Robonaut) - 07.29.14
ISS Science for Everyone
Science Objectives for Everyone
Robonaut is a two-armed humanoid robot torso designed with the versatility and dexterity to manipulate hardware, work in high risk environments, and respond safely to unexpected obstacles. Robonaut is currently mounted inside the International Space Station (ISS); in the future, it will perform tasks both inside and outside the ISS. The Robonaut Teleoperations System enables Robonaut to mimic the motions of a crewmember wearing specialized gloves, a vest and a visor providing a three-dimensional view through Robonaut’s eyes.

Previous ISS Missions
Robonaut begins operations on ISS Expedition 25/26.
- 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.

We did this experiment because we were learning about technology. We liked learning about Robonaut because robots are really cool.

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.
Robonaut not only looks like a human, but is designed to work like one, with human-like hands and arms that can operate the same tools crew members use. For initial demonstrations, Robonaut flips switches, removes dust covers, installs handrails and performs other duties using the Robonaut Task Board inside the ISS. Additional tasks are assigned to Robonaut as each session is successfully completed. With further development and enhancements, humanoid robots will be able to work alongside humans on spacewalks.
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.
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.
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.
