11.12.1. Flexible Link Dynamics

Try these first

1. 1.

   What does the Euler-Bernoulli beam theory ignore?

   Hint

   Think about what happens to a slender beam when it bends.

2. 2.

   Name a method used for controlling flexible robots.

   Hint

   This method manages vibration modes.

3. 3.

   What does the Timoshenko beam model account for?

   • Only bending stiffness.
   • Shear deformation.
   • No deformation.

   Hint

   Think about thicker beams.

4. 4.

   True or False: Modal control is used to manage vibrations by controlling each mode independently.

   • True
   • False

   Hint

   Consider how multiple vibration nodes can interact.

5. 5.

   How would you design a flexible robotic arm intended for surgical applications? Consider the dynamics and control strategies needed.

   Hint

   Think about the environment and needed precision.

6. 6.

   Devise a scenario where failures in controlling flexible dynamics could lead to performance degradation. Discuss how you would rectify these issues.

   Hint

   Consider the real-time nature of control responses.
