11.6. Dynamic Modeling of Manipulators

Try these first

1. 1.

   What is one key parameter used in modeling a robotic link?

   Hint

   Think about what affects the weight of a link.

2. 2.

   Name one modeling approach discussed in dynamic modeling.

   Hint

   This approach uses software for mathematical representation.

3. 3.

   What does the center of mass determine in dynamic modeling?

   • The reach of the manipulator
   • The balance point of the link
   • The mass of the link

   Hint

   Think about what affects how the link holds its position.

4. 4.

   Is numerical modeling different from symbolic modeling?

   • True
   • False

   Hint

   Reflect on both definitions.

5. 5.

   Given a robotic link with a length of 2m and a mass of 5kg, calculate how the length and mass distribution can affect its center of mass performance in a dynamic scenario.

   Hint

   Consider how the mass is evenly distributed along the length.

6. 6.

   If you were tasked with designing a robot arm with variable wrist angles, describe how you would apply numerical modeling to ensure proper movement without risking dynamic instability.

   Hint

   Think about how you would collect data during each movement.
