"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"

This quote by Umberto Guidoni is referring to the intricacy of a robotic arm. The robotic arm has 7 degrees-of-freedom, which suggests it can move in 7 different instructions. This makes the total movement of the arm really complicated, as it can move in a variety of ways. For that reason, prior to trying to run the arm, it is important to be knowledgeable about all the positions it can get. This is very important to make sure that the arm is run safely and efficiently. It is likewise important to understand the restrictions of the arm, as it can only move in specific instructions and particular positions. Knowing the abilities of the arm is important to make sure that it is used correctly and safely. By recognizing with all the positions the arm can get, it will be easier to operate the arm and get the wanted outcomes.
