Direct Control

This Arduino Linear Actuator Tutorial shows how to do basic manual control of a large linear actuator using an Arduino and two buttons. The first button extends the actuator and the second retracts the actuator.

Large linear actuators traditionally have five wires. Two wires are for powering the motor and three wires go the internal potentiometer for reading position. The two relays are used to toggle the positive and negative power to the motor in order to determine the direction of piston travel. The analog potentiometer is wired to one of the analog inputs on the sensor shield for reading the current position. For this project we do have the analog wired up, but we are not using the analog input in the body of the code since we are just doing simple control of driving the piston in or out.

PC Control These demos and projects allow the robot to be controlled via a computer.

ArbotiX Commander Control - These demos and projects control the Robot using the ArbotiX Commander, the handheld Arduino based remote control.

Direct Control - These demos and projects control the Robot directly from sensors connected directly to the Robot's control board.

Pose Control - These demos and projects allow you to create and playback a sequence of poses.

Serial Control - These demos and projects control the robot using a serial packet protocol.

Standalone - These demos and projects are deisgned to let your robot function without a computer or additional microcontroller.

Wireless Control - These demos and projects allow you to control the robot wirelessly - usually by replacing the Serial Connection with XBee modules.

Reference - These articles have technical details regarding the control and operation of the robot.
