From The Starfield Wiki
Vasco is Constellation's expeditionary robot. His design is based on a Type-A bipedal chassis built by Lunar Robotics, and was refurbished to meet the requirements of Constellation's mission. Vasco is capable of traversing rough terrain, and has all the survival gear needed for extended overland journeys. His primary role is peaceful but he does have the defensive capabilities in case the need arises. Vasco wears the white and red livery of Constellation, though many years in the field has worn the paint down and dented a few panels. Regardless of the many years in use, he is still the reliable companion an explorer can depend on.
