From Space.com:

A NASA robot built to ease the daily lives of astronauts in space greeted its human commander with a hearty handshake Wednesday (Feb. 15), along with a silent message: “Hello, World.”

The historic handshake between man and machine — a first in space — was shared between NASA’s humanoid robot, named Robonaut 2, and American astronaut Daniel Burbank on the International Space Station.
