What an invention? Do you know all about robots, read these interesting facts before we continue this tutorial on drawing robot. The first humanoid robot was developed in called Elektro.
The smallest robot is called nanobot. The first known robot was developed in 5 th century BC which created mechanical doves. The field of robotics has developed very much. There are vacuum cleaning robots and many other bots which helps human beings in many ways.
Ina robot called Sofia was announced officially whose behaviour at par with a human being. Some people also fear that robots will take control over the world and become a new species.
Robots can be friendly or else destructive if not programmed properly. But robots are the future of humanity. Always be focused while drawing and be innovative.
Step 1 First draw a square for the head of the robot. Just below it draw a rectangle for the body of the robot. Step 2 Draw 2 circles for the eye and draw a rectangle for the mouth. Fill the mouth with straight lines to form the teeth. Step 3 Draw a light bulb on top of the head. Draw antenna shaped ears. Step 4 Draw circles for the shoulders and joints. Draw rectangular shapes to form the arms. Step 5 Draw long rectangles for the legs and then draw semicircles for the feet.
Step 6 Detail the chest with whatever you think of such as meters, arrows and small switches.The example Draw a simple robot arm in C shows how to use transformations to make it relatively easy to draw a robot arm.
See that example for the basic explanation. This example adds a hand that opens and closes. The following code shows how the program draws its arm with the new code highlighted in blue. There are only two main additions to this code beyond what was used in the previous example. First, the code moves to the end of the final wrist segment. That positions future drawing at the end of the arm where the hand should be.
Adding more segments to a robot arm is just as easy. Add a translation and rotation to move to the end of the current segment, and then draw the new section.
The only real complication might occur if you want to draw certain parts of the arm the joints in this example on top of others. In that case, you may need to trace through the transformations more than once to draw each of the layers of pieces. Your email address will not be published. This site uses Akismet to reduce spam.

😍How to Draw Robot : Step By Step Guide😍
At the moment I can import obj files and textures, rotate, translate and scale. Problem: To simplify, robotic arm will have 3 parts, base cylinder to rotateand two cuboids. I have no problems with rotating cilinder and cuboids. But these two cuboids have to be connected and I have no idea how to do it. I can use simple sinus and cosinus functions to compute position of second cuboid when first one is rotated but I have no idea how to measure lenth of the object.
You haven't responded to the comment, but I figured I'd post this code anyways. I wrote this to render a 3D robotic hand in OpenGL. I had the blender model files for all the fingers and the hand made by someone elsewhich I exported individually to. The final result can be seen here. As you can see, I also added the functionality to change the viewpoint using the mouse. I determined the offsets for the finger phalanges via trial-and-error approach, but perhaps you can find the offset between the points using Blender as described here.
I cannot test this right now since I don't have Blender on my work computer. The code below describes as I implemented this. I broke it up so that I can write some explanation, but putting all the pieces sequentially will generate my complete function to draw a single finger attached to a hand. Now that we are set up at the origin rotated as the mouse directedwe can start off by drawing the palm of the hand. No shifting is required it is at the origin. After the palm is rendered, we move to draw the first finger.Add the following snippet to your HTML:.
I want to make a robo arm with less cost which draw cute pictures. That robot want to make my Daughter happy and it can able to dance. Project tutorial by jegatheesan. I saw a Cutest drawing robot in Kickstarter. I like it very much and want to make one such robot. So i go through my school life studies and check out trigonometry and Algebra to find out how it works and after several days i find the solution and check the result in calculation.
Then i surprised i find the solution. Lets see how I develop it step by step. I am sure even i do it with out any special tools u with tools do it very easily. In motero shiled 1 we only drive 2 servos. So i make my own shield.
I that board i use 3 X 3 Male connector to connect servos. I want to test that this servo is correct for my application. But some more calculation is missing. So some calculation want to change.
They only able to take the shape as oval. It must be weight hig than the other assembly then only it stand still when arm move. We want an arrangement to hold the servos and move up and down in the rail. Cut the pen in to two pieces and insert into the rods, The pen inner dia is more greater than the rod dia. So i insert a straw firat in to the rod and straw is tight with the rod and when pen is put over that it moves fine with out shake.
Glue it fully then only it hold the weight. This acts to lift the arrangement smoothly. I reduce the work of arduino by increase the work of the Computer. Arduino turns the servos degrees as per pc command.AxiDraw machines are available for purchase directly from Evil Mad Scientist as well as from select distributors:.
The AxiDraw is a pen plotter, which is a type of simple robot. Its sole function is to guide a pen or other implement mounted in the pen holder along the set of vector lines, curves, and paths that you ask it to follow. Everything that the machine is ultimately capable of, such as drawing graphics, writing text, or signing documents, are expressions of this basic function. It is capable of drawing essentially anything that can be composed from a set of lines.
In practice, this is much like using a traditional printer, except that you need to take care that your documents are made of of paths, rather than pixels. The AxiDraw is an extremely versatile machine, designed to serve a wide variety of everyday and specialized drawing and writing needs. You can use it for almost almost any task that might normally be carried out with a handheld pen.
The most common uses are: As a signature machine for checks, diplomas, headshots, etc As a "handwriting" machine for various purposes Digital artists, using AxiDraw to plot their artwork As a versatile fabrication tool. AxiDraw does not require proprietary pens or ink: you can use your own pens, chosen within certain guidelines. A larger XL Pen Clip is available as well to fit larger pens.
Good choices for pens to use include fountain pens, permanent markers, liquid-ink rollerball pens, technical pens, small-bodied whiteboard markers and other writing and drawing instruments that do not require significant downward pressure.
You can read more about pen choices in our documentation here. AxiDraw does not require special paper; you can use almost any kind and size of paper. You can even use all kinds of things that are not paper.
The larger size models have about twice this travel. You can work with any size of paper up to the size of the travel area.
You can write directly onto small pieces like business cards or a whole array of themmedium size pieces envelopes and note cards, or sheets of paper. You can also work with paper larger than the travel area. The unique design of the AxiDraw features a drawing head that extends beyond the body of the machine, making it possible to also draw on flat objects bigger than the machine itself.
For example, you can set it right on top of a box to write an address. You can even set it on top of a poster board, chalkboard, or whiteboard to draw graphics in place. For most applications, the standard-size AxiDraw V3 is the best choice. It's our top-of-the-line machine, and includes a few nice accessories as well. Available AxiDraw accessories include alternate pen holders, a tripod mount, a rigid mount that can be used instead of the pen slide, extended feet, extra clip easels, and magnetic workholding easels.
You can find them listed here at Evil Mad Scientist. AxiDraw requires a reasonably modern computer Mac, Windows, or Linux with an available USB port and internet access to download software.
Linux requirements: Recent versions of Ubuntu and similar widely-supported distributions work well. If you are using an obscure or "challenging" distribution, we'll still do our best to help you out.
If you get a head start by reading the user guide and installing the software, you can be up and plotting five minutes after opening the box. If you would prefer a model that requires assembly, there is now also AxiDraw MiniKit which comes as a kit. Internet access is required only for downloading software and for access to online documentation. Internet access is not required while preparing files or using AxiDraw. A universal-input plug-in power supply is included with the AxiDraw.
For other regions, an inexpensive plug shape adapter will be needed. Most users just make a file or drawing and plot it.An interactive robot that anyone can make!

Fixing my drawing incapability with my robotics skills and to me results were not that bad. Now I can at least save my self from humiliation in my drawing class. This project is good for beginners and gives sufficient exposure to arduino, matlab coding and mechanics. There is not much in the electronics department. The bot is a basic 2DOF arm with a pen manipulator.
This project involves application of inverse kinematics and canny edge detection. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.
You can take any servos with torque greater than 7Kg. From the pictures above you get the idea of what the design is and how you should go about assembling it. It is more like playing with maker kits when you were 5 or 6 years old. So lets start step by step construction. While construction two points should be kept in mind that the distances mentioned above should be 20 cm and calibration should be done properly. Rest of the construction depends on the availability of parts and your wish.
For example instead of aluminium stripes from the kit you can use rulers for arms etc. The picture above is self explanatory you can either make a shield for the arduino as I have done or a bread board for the circuit.
First we take an image and find its edges with the help of canny edge detection and we are going to draw this image. Drawing the image has two parts. PART 1: First we find the pixel which is 1 as our image is now in the form of 0s and 1s and then check its local pixels if any one of them is also 1 then the pen reaches that pixel and deletes the previous 1.
The function repeats it self recursively and creates smooth lines. PART 2: The second part involves the inverse kinematics part of how to reach that particular pixel.
It simply takes in the coordinates of the pixel and calculates the corresponding angles for the pivots, the calculations are shown in the above picture. The above explanation is not required for the execution of the code it is just for understanding.
First install the arduino IO package on matlab all the instructions are given with the package. See to which port your arduino is connected and then go to finaldraw. Change the extension of the image which you want to draw to.
This can be done in any image editor now save this image to the matlab directory. Open the finaldraw. Save the finaldraw. I have uploaded the picture of emma watson as a sample, so you can use it for testing and you can also adjust the parameters of the canny edge detection function according to your need. We are done now connect the arduino to your PC and switch on the power supply and type finaldraw in matlab command line.
The working of the algorithm is very simple, it is just the matter of visualizing how the bot approaches the image drawing. Firstly, I convert the the image that I want to draw in png format using some image editor, then I save the Image in the matlab directory.
Now our algorithm converts this image using canny edge detection as given in the image above. The mysterious part is drawing this image.
What the algo does is it starts checking the pixels of the converted image and when it finds 1 which is indicated as the white pixel in the image above, the pen tip reaches that point The reaching part is covered in the previous step clearly and puts the pen down then it checks neighboring 8 pixels, if it finds a 1 it reaches that point without lifting the pen up and deletes the previous pixel to avoid repetition.
Now this continues till it finds no 1s in the neighborhood this is a recursive function hence it draws smooth line deleting it simultaneously. Then it completes other branches of lines that emerge from the drawn line as it checks every neighboring pixel.
