At A Glance
The Flight Systems Branch provides robotic systems management, analysis, and engineering support for robotic systems, robotic mechanical/ electrical interfaces and workstation simulation interfaces for robotic operations that occur in extreme environments.
The Flight Systems Branch also provides countermeasure system management and engineering support for reduced and microgravity exercise equipment and the supporting hardware/software that sustains a human’s health in environments in and beyond low earth orbit.
The Flight Systems Branch provides System Management expertise for robotic and crew exercise (countermeasure) equipment on-board the International Space Station (ISS), providing engineering support, analysis, and sustainment of the flight hardware.
Our engineers interface with the ISS Program, International Partners, Commercial vehicles, and Human Health experts amongst NASA centers to integrate their needs and interactions with the flight hardware we develop and maintain.
Our Role in Flight Projects
As robotic system and subsystem managers, the Flight Systems Branch assists external payload customers with payload robotic interface design and verification; providing them with understanding and guidance to meeting the requirements placed on them.
Our countermeasure engineers work with human health personnel and crew to not only maintain but continually improve the exercise equipment on orbit and to provide lessons learned and insights into the design of future exercise equipment.
What We Need
• Accurate payload, hardware interface, and system models/simulations.
• Requirement documents, payload and interface testing/verification plans, and operational (trending) data with respect to our flight systems.
Challenges We Face
• Loads imparted on crew, vehicle, and hardware during system operations which is why testing and analysis is a critical function.
• Exercise equipment not being considered as a system in future exploration vehicle design.
When We Engage
The Flight Systems Branch engages whenever there is a flight system anomaly on-orbit, when a new payload/hardware that will interface with our system is receiving requirements, and whenever an evaluation of a future capability is needed.

The Robotics Systems experts at NASA/JSC provide systems engineering, development, integration, and testing of robotic hardware and software technologies for robotic systems applications. We work with customers to refine robotic requirements, interfaces, and concept of operations. Our analysis capabilities include failed capture clearances and robotic hardware and payload load assessments during capture and berthing activities. Our simulated robotic workstation capability provides 3D scenes from the operator’s point of view overlaid with dynamic graphics showing vital information such as approach corridor and abort boundaries, allowing full interactive control of cameras, robotic arms, end effectors, and visiting vehicle/payload commands.
The Robotics Workstation (RWS) is the crew’s interface to Mobile Servicing System (MSS) operations. The MSS is the robotics system provided by the Canadian Space Agency and consists of the RWS, the Space Station Remote Manipulator System (SSRMS), the Mobile Base System (MBS), and Special Purpose Dexterous Manipulator (SPDM). The RWS enables the crew to issue commands and receive telemetry from the MSS components, including video camera routing and control of both external ISS cameras and cameras mounted on the robot arms. The crew uses the RWS to control the SSRMS during Extra-Vehicular Activities and for Free Flyer Visiting Vehicle captures and releases. Also, there are several graphical overlays that are used by the crew on the RWS monitors to aid them in monitoring the visiting vehicles’ approach and departure trajectories.
The Simulated Robotic Workstation Lab (SRWS) is an ER3 operated facility that has functionally equivalent software and Off-The-Shelf hardware that function similarly to the RWS on board the International Space Station.
The SRWS team supports MSS software modifications and performs integrated testing to ensure consistency with operational concepts, expected functionality, and compliance with ISS program requirements. The focus is on updates to the RWS flight software and interfaces to the Command and Control System (CCS), the main ISS computer, as well as integrated RWS testing. The team is instrumental in development and testing of Visiting Vehicle overlays for all robotically captured Visiting Vehicle missions.
In addition to their primary work, the SRWS team has developed application software for use by Flight Operations Robotics Flight Controllers to use for development and execution of their procedures, scripts, etc.
• MCT – MSS Application Computer (MAC) Controller Tool provides situational awareness of scripted MSS operations to the Robotics Flight Controller or Robotics Officer (ROBO) user for status monitoring. It provides the ability to select and configure scripts and send commands to the MAC. The MCT supports multiple simultaneous positions to allow monitoring users to verify inputs and commands of the active user.
• TIDE – Thicklayer Integrated Development Environment (TIDE). TIDE is a new tool that helps the ROBO Flight Controllers write ground scripts that will automate procedures.
• There are plans to work on several projects for the ROBO flight controllers that will be started soon.

A spin-off of the Robonaut hand and limb technology, exoskeleton devices have many useful benefits for both space and terrestrial applications. In-space, exoskeletons can be used as a force resistive device to enable exercise in a weightless environment or enhancing an astronaut’s grip in a space suit glove. Here on earth, exoskeletons serve multiple purposes:
• Grasping assist
• Prevent fatigue and repetitive stress injuries
• Rehabilitation Strength augmentation
• Walking assist for the disabled
The Exploration Exercise System Management experts at NASA/JSC enable human exploration mission success by developing and managing systems of exercise and monitoring capabilities that contribute to the effective sustainment of crews’ physical condition in all crewed environments beyond Low Earth Orbit.
We perform research and development and stay current on the latest technology advances to continuously evolve innovative exercise capabilities for long duration exploration-class vehicles and habitats that:
• Significantly reduce mass, volume, and power consumption compared to ISS,
• Improve reliability and modularity to minimize sparing logistics and crew time required for maintenance,
• Have intuitive operational interfaces, Integrate multiple exercise modalities and other exercise benefits (e.g. sensorimotor, monitoring), and
