Which statement is true about the relationship between a six-axis robot and its movement?

• A. It can move in six independent axes
• B. It has only four joints
• C. It cannot rotate
• D. It has five axes

Answer: (A)

A six-axis robot has six independent axes of motion, giving it six degrees of freedom: three translational (x, y, z) and three rotational (pitch, yaw, roll). This combination lets the end effector reach any position in 3D space and orient itself in almost any direction within its reach. That’s why the best description is that it can move in six independent axes. The idea of six joints providing both positioning and orientation is what sets six-axis robots apart from robots with fewer axes, which have more limited movement and cannot rotate as freely.
