    What are they?

    Some are flat, others raised and sometimes angled.

    Thanks

    "In order to line up this new piece of truss with the one already
    installed on the laboratory, we used a system called the space vision
    system (SVS) in addition to the camera views. This system determines the distance between strategically placed black dots on the previously
    installed structure relative to the piece of structure that is being
    installed. "

    The Shuttle's Canadian-built mechanical arm has been enhanced with a new
    "Space Vision System" (SVS) that will help the operator literally see
    around corners. Tested on past Space Shuttle missions STS-74, STS-80 and STS-85, the SVS uses video image processing and a series of markings on
    the objects being maneuvered to develop a graphical laptop computer
    display to assist the arm operator. It allows the Shuttle arm to
    be operated with great precision even when visibility is obstructed, and
    the system was used operationally for the first time during the first
    assembly mission as astronaut Nancy Currie, with her view partially
    obstructed, attached the first station component, the Zarya control
    module, to the second component, the Unity connecting module.
