Approximately after 4.5 hours of printing all the parts are ready to be assembled. The Design is pretty plain and hence can be easily handled by any basic 3D printer. Luckily none of the parts have over hanging structures so supports are not needed. If you want to know more on 3D printer and how it works you can read this article on Beginners Guide to Getting Started with 3D Printing. I used the Cura 3.2.1 Software from Ultimaker to slice the STL files and my TEVO tarantula 3D printer to print them. There are totally 14 parts which has to be printed and the STL files for all of them can be downloaded from Thingiverse page. So get to his Thingiverse page (link given above) and download the model files. So I went through the designs and found that the Robotic Arm V2.0 by Ashing will work perfectly with our MG995 Servo Motors and would exactly suit our purpose. Initially I started by designing the body using Solidworks, but later realised that there are many awesome designs readily available on Thingiverse and there is no need to re-invent the wheel. The most time consuming part in building this robotic Arm is while building its body. If you don’t have anything then you can just use cardboards to build simple Robotic Arm.ģD Printing and Assembling the Robotic Arm ![]() Else, uses the 3D model provided and machine your parts using wood or acrylic. If you have a printer you can print them using the given design files. Note: The body of the robotic arm is completely 3D Printer. Sounds cool right!!! So lets start building. Apart from that we will also program it to have a Record and play feature so that we can record a motion and ask the Robotic Arm to repeat it as many times as we require it. The Robot will have a total of 4 Degree of Freedom (DOF) excluding the gripper and can be controlled by a potentiometer. So, in this tutorial we are going to build our own Robotic Arm with the help of Arduino and MG995 Servo motors. These robotic arms are used in Production line of automobiles, mining plants, Chemical industries and many other places. Apart from the fictional world there are many cool real world Robotic Arms made by Fanuc, Kuka, Denso, ABB, Yaskawa etc. and this is where I would like to stop it because this is no fan Page. Actually Dum-E has also saved his life once. ![]() These two bots can be seen helping him while building the Iron man suits or filming his work using a video camera. I have always wished for a robotic arm that could help me with my daily works just like Dum-E and Dum-U that Tony stark uses in his lab. But to me, what’s more than that is these things are cool to look at when they work. Robotic Arms have proved themselves useful and more productive in many applications where speed, accuracy and safety is required.
