daGHIZmo designed a 3D Robotic Arm called EEZYbotARM and uploaded the files in Thingiverse website.įor 3D Model files of the Robotic Arm, please visit this link.īased on those 3D model files, we made the parts using a local 3D Printer outlet. So, we decided to go for 3D Printed Parts for the Robotic Arm. One of the important feature of any Robotic Arm project is the aesthetics. We have chosen this particular servo because the regular plastic gear servos were not stable and also the stall torque is less.Īt 6.6V supply, this metal gear servo provides a stall torque of 2.2Kg/CM (which is considerably more than that of the regular SG90 Servo). The Servos used in the Robotic Arm construction are TowerPro MG90S Metal Gear Micro Servos. Android Phone with custom application installedĪrduino UNO and Bluetooth Module are pretty straight forward in the list of components but the interesting components are the Metal Gear Servos and the 3D Printed Robotic Arm parts.Proper power supply for Arduino and 4 Servo Motors.3D Printed Robotic Arm Parts with necessary screws, nuts and bolts.4 x Tower Pro MG90S Metal Gear Servo Motors.The circuit diagram seems very simple but the construction part of the Robotic Arm is a little bit complicated.Ĭomponents Required for Robotic Arm Project The following image shows the circuit diagram with all the necessary connections. Let us start with the circuit diagram of the Arduino & Bluetooth Controlled Robotic Arm Project.
