### What are the two main attributes used to define objects at a beginner level in the context of mechanical manipulators?

Position and orientation

Kinematics

Joint angles

### What term is used to describe the number of independent position variables required to locate all parts of a mechanism in the context of mechanical manipulators?

Degrees of Freedom

End effector

### In the context of vectors, what does a 3x1 position vector represent?

Location in space

### What is the significance of describing orientation of a body with respect to a coordinate system?

It gives the complete location of the body

### How are unit vectors that describe orientation typically arranged for a body relative to a reference system?

$egin{bmatrix} X & Y & Z \ \ \ \ \ \end{bmatrix}$

### If given $A_{P} = egin{bmatrix} 2 \ -3 \ 5 \ \ \ \end{bmatrix}$, what does the value of $p_{y}$ represent?

Distance along the y-axis

### Why is it important to specify both the location and orientation of a body in space?

To fully define the body's position

Learn about the mechanics of mechanical manipulators and how to locate objects in 3D space. Understand the concepts of position, orientation, frames, and reference coordinate systems in manipulating objects.
