GITAI USA Inc.’s newest robotic system, S2, this week launched aboard a SpaceX Falcon 9 rocket headed for the International Space Station. It is a part of a mission to resupply the ISS and to check improvements together with a surgical robotic and a steel 3D printer. The system arrived immediately.
S2 is the Torrance, Calif.-based firm’s dual-armed robotic system. Now that it has been delivered, the ISS crew will mount S2 on the Nanorack Bishop Airlock, and the robotic conduct an exterior demonstration of in-space servicing, assembling, and manufacturing (ISAM).
“Our robotics systems are capable of conducting various operations, such as maintenance, inspection, and life extension operations for the target satellite,” acknowledged Sho Nakanose, the founder and CEO of GITAI.

Inside GITAI’s manipulator robotic
GITAI mentioned it designed S2 for reliability and adaptability. The firm constructed all of its expertise with elements developed fully in-house, so it may possibly commercialize these elements sooner or later, famous Nakanose.
“Unfortunately, there weren’t any good suppliers in the market,” he informed The Robot Report. “The space robotics field is a very new business domain. So there’s no supply chain in the industry. So if we wanted highly capable and affordable robotics for spacecrafts, we needed to develop everything in-house.”
GITAI geared up S2 with two 1.5 meter (5 ft.)-long arms that the corporate mentioned will improve its work efficiency. This would be the first time GITAI will check its dual-armed system on the ISS.
The firm’s earlier demonstration onboard the ISS concerned its S1 autonomous area robotic. S1 solely has one arm, and was capable of execute two duties: assembling buildings and panels for in-space meeting (ISA), and working switches and cables for intravehicular exercise (IVA).
“For our first demonstration, we had to realize the performance of the robotic system and show it’s capable of conducting very complex operations, such as assembling smaller parts,” Nakanose mentioned.
S2’s jobs on the ISS
Along with demonstrating the advantages of getting two robotic arms work in cooperation, S2 plans to point out off GITAI’s new software changer. The firm mentioned it hopes to show the general-purpose software changer’s precision and robustness.
Nakanose mentioned the software changer is a key a part of S2. GITAI’s clients, that are spending massive quantities of cash to even get this expertise into area, are occupied with techniques that may do numerous work, so flexibility is essential, he mentioned.
“As far as our ISS demonstration, we have two kinds of end effectors,” defined Nakanose. “One is, of course, a pinching robotic hand, and the other is a robotic screwdriver.”
S2 can have 4 duties it must carry out on the ISS. The first is putting in a process panel in place. According to GITAI, element alternative is essential for area station upkeep and satellite tv for pc life. Robots like S2 may present extra exact manipulation than human astronauts.
In addition, S2 will screw and unscrew tiny captive bolts robotically, in addition to display its skill to govern sheets of versatile supplies like thermal blankets. Finally, S2 will mate and de-mate a versatile electrical cable with a connector that’s tied to the ISS.

GITAI readies S2 for the ISS, future missions
Before GITAI and SpaceX may launch S2 to the ISS, the robotic wanted to cross all of NASA’s Safety Reviews and obtain NASA’s Technology Readiness Level (TRL) 6. According to Nakanose, NASA’s Safety Reviews are exhaustive, as NASA wants to make sure any expertise heading to the ISS is totally protected for astronauts to work round.
“With spacecrafts, there’s a history of robotic systems being very complex and risky for [NASA],” Nakanose mentioned. “So, it’s a really important program. We had to make sure our product is totally safe, and our system has necessary countermeasures for safety.”
“We succeeded in passing all the National Safety review in probably 10 months,” Nakanose mentioned. “So it’s very quick. Generally speaking, you will take a few years to pass the safety review.”
By finishing this mission, GITAI mentioned it goals to achieve TRL 7. NASA’s TRL system is used to evaluate the maturity ranges of a selected expertise. Level 7 implies that the system prototype has been demonstrated in an area setting.
At Level 9, the very best degree, NASA declares {that a} system has been flight-proven by profitable mission operations.
Moving ahead, GITAI has plenty of buyer contracts on the horizon. Nakanose mentioned they embrace contracts with Toyota and JAXA, the Japanese Aerospace Exploration Agency, and a DARPA contract to make use of its robots to construct infrastructure on the Moon.
