The astronauts moved a Latching End Effector (LEE), or hand, for the Canadian-built robotic arm, Canadarm2, from a payload attachment on the station's Mobile Base System rail car to the Quest airlock. They also moved an aging, but functional, LEE that was removed during a January 23, 2018 spacewalk from its temporary storage outside the airlock to a long-term storage location.
