"In particular, this arm has 7 degrees-of-freedom that makes the overall motion of the arm very complex so that, before you start driving the arm, you should be very familiar with all the position it can get"
About this Quote
The intent is instructional - a preflight briefing compressed into one sentence. Guidoni flags a core truth of space work: more capability multiplies not just what you can do, but what you can do wrong. A 7-DOF arm can reach around obstacles, orient tools, compensate for constraints. That same flexibility also means an explosion of possible configurations, some of which will be counterintuitive, unstable, or collision-prone. "Before you start driving the arm" frames operation as piloting, not pushing buttons; it implies skill, rehearsal, and a mindset that treats motion as a chain of consequences.
The subtext is about humility. Familiarity here is not casual familiarity, its muscle memory backed by procedures, simulation, and checklists. The slightly awkward phrasing - "all the position it can get" - reads like translation, but it also feels unvarnished, almost intentionally plain: no poetic distance, just the reality that the machine will do exactly what you command, not what you meant.
Contextually, this fits the era of shuttle and ISS robotics, where Canadarm-style systems made astronauts into both engineers and choreographers, responsible for navigating a three-dimensional minefield with millimeter precision.
