Linear Actuators for Robotics

Robotics play an integral part in the world’s industrial automation world. Linear actuators for robotics are complex systems that help drive robotic motions, navigation, and interaction with objects.

Types of Actuators Used for Robotics

Robotic actuators typically fall within two categories: linear motion and rotational motion. Linear robots rely on a linear motion that produces a back and forth movement.

A rotational motion actuator for robotics is the opposite of a linear actuator. Instead of moving in a straight line, a rotational motion actuator will turn a component. It can move something within a degree of a circle or spin on an axis indefinitely.

For Linear Motion Activity

Linear Actuators

Linear actuators in robotics can take on several forms based on their energy to move their motor shafts. Hydraulic actuators are ideal for handling heavy loads because their motor chamber contains hydraulic fluid. Applying pressure to the fluid pushes the output shaft or piston linearly.

Another common type of robotic actuator for linear motion is the electric actuator. This actuator uses energy to produce back and forth actions with high precision.

Solenoid Actuators

These robotic linear actuators are best for equipment that includes valves, locks, or latches because they remotely provide movement to control switches. It also works well for robotics that pushes buttons. Solenoid actuators can perform these functions because they take on binary positions, like open/close and on/off. 

For Rotational Motion Activity

DC Motors Actuators

A DC motor is an electric actuator that uses DC voltage across the motor terminals. It has a positive (+) and negative (-) terminal. When the output shaft encounters the voltage, it will spin based on the extent of the electricity.

Servo Actuators

These actuators have a DC motor, control circuitry, and output shaft in a single component to produce continuous 360-rotations. Computers inside the robots can control servo actuators through PWM signals to rotate at the desired angle. 

Stepper Motor Actuators

Another common type of DC motor is a stepper motor actuator. They contain multiple coil sets called steps. The motor will turn one step at a time to create precise movements.

Factors to Consider While Choosing Actuators for Robotics

When looking for suitable linear actuators for robotics, you must consider your design’s function and purpose to determine the actuator’s purpose. For instance, a servo motor is best if your robot has an arm that requires articulation and manipulation of objects. 

Also, take the size and weight of the actuator into consideration. It should be small enough to fit within its chamber without being too heavy to move the robot.
