s-one

S-One is a Japanese robot made by Tokyo-based company Schaft to compete in the Robotics Challenge, a DARPA-organized competition with an aim to "discover" the most up-to-date humanoid robots.
S-One won the competition with 27 points out of 32 by completing tasks such as clearing the ground of objects and passing through debris without difficulty. The S-One lost points when it was unable to exit from a vehicle.

    • Beaverton
    • Oregon
    Hi all, I've got an Aero Precision Atlas R-One 15" MLOK Handguard in black. This is the one with full length picatinny rail. I'd like to switch it out for a 15" S-One (no upper rail), also in black. It is mounted on an upper, but barely used and looks perfect. Anyone up for a trade? Thanks, Sean
