8.2. Classification of Actuators

Try these first

1. 1.

   What does an actuator do?

   Hint

   Think about what moves a robot.

2. 2.

   Name one type of electrical actuator.

   Hint

   This type is used for precise control.

3. 3.

   What type of actuator is best for precise angular motion?

   • DC Motor
   • Servo Motor
   • Stepper Motor

   Hint

   Think about which motor has feedback control.

4. 4.

   True or False: Pneumatic actuators use hydraulic fluid.

   • True
   • False

   Hint

   Consider the type of fluid each actuator type uses.

5. 5.

   Given a scenario where a robotic arm must lift heavy materials and also perform precise positioning tasks, which actuators would be most appropriate?

   Hint

   Consider the weight of the materials and the need for detailed movements.

6. 6.

   Analyze the potential limitations of pneumatic actuators in sensitive environments where precise control is critical.

   Hint

   Think about how air pressure fluctuations affect movement.
