Next place a servo motor in the middle and glue it in place. Take a flat and stable surface, like a table or a hard card board. In Arduino we have predefined libraries to control the Servo, so it is very easy to control servo, which you will learn along with this tutorial. Go through this tutorial of Controlling Servo Motor using Arduino to learn more about it. The RED wire is connected to power, Black wire is connected to ground and YELLOW wire is connected to signal. A servo motor will have mainly there wires, one is for positive voltage another is for ground and last one is for position setting.

We are going to use small servo motors, here we use four SG90 servos. Servo motors are available at different shapes and sizes. So these motors are best for designing robotic arm. Servo motors are proposed for low speed, medium torque and accurate position application. These are not proposed for high speed applications. Servo Motors are mainly used when there is a need for accurate shaft movement or position. Components Requiredįirst we talk a bit about Servo Motors. Also check our other Robotics Projects here. The whole process has been well demonstrated in the Video at the end. We have used low torque servos here but you can use more powerful servos to pick heavy objects.

You can move these servos by rotating the pots to pick some object, with some practice you can easily pick and move the object from one place to another. This Arduino Robotic Arm can be controlled by four Potentiometer attached to it, each potentiometer is used to control each servo. This project will be helpful for beginners who want to learn to develop a Simple Robot in low cost or just want to learn working with Arduino and servo motors.

This setup also looks as a Robotic Crane or we can convert it into a Crane by doing some easy tweaks. Here in this project Arduino Uno is programmed to control servo motors which are serving as joints of Robotic arm. Entire process of construction has been explained in detail below. In this tutorial, we are going to design an Arduino Uno based Robotic Arm from some cardboards and servo motors.
