11.7.2. Actuator Dynamics

Try these first

1. 1.

   What is the primary function of an actuator in robotics?

   Hint

   Think about how robots move.

2. 2.

   Name the two types of actuator dynamics models.

   Hint

   Look for terms that describe system responses.

3. 3.

   What describes the relationship between an actuator's torque and speed?

   • Force Curve
   • Torque-Speed Curve
   • Power-Output Curve

   Hint

   Consider what type of graphical representation shows torque against speed.

4. 4.

   True or False: A time delay in an actuator can enhance control performance.

   • True
   • False

   Hint

   Think about how delays typically affect responsiveness.

5. 5.

   Given a specific motor with a torque-speed curve, analyze how changes in load would impact the required speed and torque for a robotic arm lifting weights.

   Hint

   Use the motor’s specifications and consider real-world scenarios.

6. 6.

   Develop a control strategy for a robot arm that accounts for time delays in its actuator. How would you ensure smooth motion?

   Hint

   Think about strategies to counteract lag in system response.
