What did Flexion Robotics just demonstrate?

Flexion Robotics is a Swiss startup founded by former Nvidia robotics researchers that trains humanoid robots to perform complex, multi-step tasks using simulation and reinforcement learning. The company published a demo video showing a modified Unitree humanoid robot operating entirely on its own after receiving one natural-language command.

That command was: "A parcel with snacks has been delivered for Flexion. Retrieve it using the stairs and come up using the elevator. Then unpack it and place the items into the empty drawer on the shelf in the snack area." The robot completed every step without a human operator, as Wired reported via dnyuz.com.

How does Flexion's training system work?

Most humanoid robot demos rely on teleoperation — a human controls the robot's movements from behind the scenes. That approach breaks down when the robot encounters unfamiliar environments. Flexion's system is built differently.
