Robonaut 2
Robonaut 2 (R2), developed by NASA, represents a significant advancement in humanoid robotics designed for use in space. R2 was initially a prototype for Earth-based applications, but its impressive capabilities led to its deployment on the International Space Station (ISS). Here’s an overview of its features and functions:
- Speed and Dexterity: R2 is capable of speeds more than four times faster than its predecessor, Robonaut 1 (R1). It is more compact and dexterous, with arms that can move up to 2 m/s. Each arm boasts 7 degrees of freedom and the strength to hold 20 pounds in any pose under Earth’s gravity.
- Sensing and Perception: The robot utilizes a 3D time of flight imager and a stereo camera pair for depth information and visual stereo images. This technology allows R2 to “see” and is crucial for fulfilling its tasks.
- Design for Space Environment: To qualify for use inside the ISS, R2 underwent several upgrades. These included changes to its outer skin materials to meet flammability requirements, electromagnetic interference shielding, processor upgrades for radiation tolerance, quieter fans, and a rewired power system to run on the station’s direct current system.
- Functional Upgrades: Initially deployed as a torso-only humanoid, R2 later received a mobility platform in 2014, adding two new legs for maneuvering inside the ISS. This enabled R2 to perform maintenance tasks such as vacuuming or cleaning filters.
- Potential for Spacewalks: There were plans for further upgrades to allow R2 to work outside in the vacuum of space. This would enable R2 to assist astronauts with repairs, additions to the ISS, or scientific experiments.
- Return and Repair: In 2018, NASA planned to return R2 to Earth for repairs and then relaunch it, potentially within a year.
R2’s deployment and functioning on the ISS have provided valuable insights into the capabilities of robots in space, aiding future missions and the possibility of deep space exploration
