Control Robotic Arm – An Arduino and Android Based $100 DIY

No point for guessing this DIY requires as much mechanical proficiency as electronic. And yet, this isn’t a particularly tough project (just requires a bit of machine shop work). Ashraf Nabil shows you how to send the mobile sensors data via Bluetooth to Arduino using 1Sheeld and then controlling the motion of the servos. Check out the video below for an illustration.

He made this android controlled arm with Arduino Uno, 1Sheeld, Servo X2, a gripper for Robotic Arm with 2 DOF, any Metallic heavy Base, a strong adhesive and finally an Android Smart Phone. It did not cost him even $100 to make it (given that he did not have to buy a smartphone). The project was initiated by creating the robotic arm first. He calculated what load each servo would carry so that the right servo with the required torque could be made available. For Android interface, Ashraf download 1Sheeld application from Play Store for no charge.

There is a second video below that shows the updated project. What Ashraf has done it is he has moved the project from arduino to Intel Galileo. As you may notice, the finishing in the design is better in the second video even if the control appears imperfect.
