French term or phrase: à l’espace articulaire
Context:
-composant 104 de génération de trajectoire, configurable pour générer une trajectoire cartésienne ou articulaire, i.e. qui génère la trajectoire cartésienne que doit suivre l’extrémité du robot dans l’espace, ou la trajectoire articulaire que doit suivre chaque articulation du robot, à partir d’un ou plusieurs points de destination fournis par l’utilisateur ;
-composant 106 de conversion de l’espace cartésien à l’espace articulaire, également appelé module MGI pour modèle géométrique inverse ;

An editing task in which this has been variously translated as joint or articular

-trajectory generation component 104, configurable to generate a Cartesian or articular trajectory, i.e. which generates the Cartesian trajectory to be followed by the end of the robot in space, or the articular trajectory to be followed by each joint of the robot, from one or more destination points provided by the user;
-component 106 for conversion from Cartesian space to articular space IGM,

I would like confirmation about articular as oposed to joint.
TIA Chris.

English translation:articular space
Explanation:
"l’espace articulaire" is the "(3-dimensional) space" covered by the movement of the articulated robotic arm, with its own "coordinate system" (thus the need for: "-composant 106 de conversion de l’espace cartésien à l’espace articulaire, également appelé module MGI pour modèle géométrique inverse")

You can also find the ambiguous "joint space" - the meaning seems to be exactly the same - so better stick to only one term consistently.

It is often desired to control the end effector of an articulated robot more accurately in Cartesian space than in joint space. Operational space control is a

2 Joint Space Trajectories
• PRO: Actual control of the robot occurs in joint space
• PRO: Simpler to plan trajectories in real-time; less computation
• PRO: No problem with singularities
• CON: Actual robot position is sometimes unclear, particularly in presence of known obstacles (e.g. is the
robot below or above the work table?)
3 Cartesian Space Trajectories
• PRO: Path we desire is usually a Cartesian path - how we reason about 3-space

Abstract:
Dynamic movement primitives (DMPs) were proposed as an efficient way for learning and control of complex robot behaviors. They can be used to represent point-to-point and periodic movements and can be applied in Cartesian or in joint space.
