LINEAR ACTUATORS IN ROBOT’S MOTION

Linear Actuators in Robot’s Motion   

Introduction

A robot motion can be controlled by Linear Actuators (for example www.progressiveautomations.com/track-linear-actuator). A linear actuator is an electric device that used in converting the revolving motion of a DC motor into linear movements. Linear movements refer to the pull and push movements that make it possible to lift, push, tilt or pull objects simply by using a remote. Linear actuators are useful in robotic applications to help them in performing such movements.

Methods

There are multifaceted methods of using linear actuator to perform robotic motions. However, a simple method requires an external source of power popularly a DC motor which is attached with a gearbox. One can use an external control box such as PLC where one plugs in the actuator’s plug into a control box. If one does not wish to use a control box they can cut the plug and stick the two wires into a battery or switch.

Requirements

The general tools required include an aluminum sheet, a driller, fasteners, and two sets of small wheels. The aluminum sheet is used to install the motor to the robot’s body by drilling two holes into the bottom right and top left of the aluminum sheet. The fasteners on the other hand are used to install the motor onto the robot by drilling two holes into the motor’s installation panel.

How It Works

The first step involves connecting the servo motor controller to the Direct Current motor and connecting the servo motor controller to the micro controller. This ensures that power is supplied to the actuator and the robot. The servo ensures the correct voltage is supplied to the linear actuator while the micro controller also helps on determining the amount of power needed to run the robot and the actuator. The wheels are then installed on the robot to provide motion to the robot. The wheels are attached to the robot and the motor by drilling holes on them and fastening them properly onto the devices using the fasteners. After the motor is turned on, the amount of power required to run the application should be adjusted. The control boxes and remote controls allow a person to control the movement of the linear actuator.
