Making an 8DOF Quadruped

Image
  I tried my hand at making a Quadruped Robot; an 8-DOF one as opposed to the typical 12-DOF ones. It is still very much a WIP, but I just couldn’t wait to make a post about it. In the top most photo you can see how it is taking serial inputs from a GUI application. The application itself was made using Processing. The GIF below shows how I send the servo values using the interactive knobs and pressing the respective servo buttons. For instance, HLF would mean Hip Left Front and KLB would be Knee Left Back. So if I set the HLF knob to be of a certain value, and then press the HLF button, it will send a command to move the front left servo connected to the hip, to the desired position. The GUI establishes Serial communication with the Arduino.  Spent so many hours 3D Printing the body. (The STL files were obtained from this Instructables page ). To provide sufficient current to all my servos, I al...

Fixing the "A software problem has caused Meshmixer to close unexpectedly" Problem

Image
Anyone who works in the 3D Printing sphere can attest that Meshmixer is an amazing software when it comes to mesh repair, cutting up prints into smaller parts and for adding some last minute digital sculpt alterations to our models. But how would one even get to enjoy what Meshmixer has to offer if it crashes every time you open it? Well, luckily I have found a solution for this! Firstly, make sure you have tried the solutions given in the official Meshmixer FAQ page. If it still doesn't work, then you can try solution number two! From my limited understanding (and scouring of internet forums), the problem could be that we do not  have a graphics card that has built-in OpenGL support. Thus, we need to place the opengl32 library file in Meshmixer's file location. Here is the link for the opengl32.dll file. But a google search for opengl32.dll will help you find another link as well. (Note the size should be 25MB so be mindful of that when installing the file.) This video  helpe...

An attempt at creating "ASCII" Art but with Unicode characters

Image
Following a quick read of this article on Medium [4], I felt tempted to try my hand at making ASCII art. Well, ASCII art but including Urdu/Arabic characters in it. So in other words, not “ASCII” art at all. This means we’re going beyond the realm of a restrictive 127 character set. Making ASCII art has been tried and done hundreds of times. For this project, I used C++ (my go-to programming language). Upon researching the working principle behind ASCII art [10] and how others approached this in C# [2], Python [4] and JavaScript [3] , I found that implementing an intensity-dependent program is the simplest solution. It can be summed up in 4 steps. 1) Set a char array with several characters sorted by “intensity” 2) Get a grayscale, contrast-adjusted image. 3) Loop through each pixel and select a corresponding character for each pixel, based on the grayscale value (0-255). 4) Print out the corresponding characters. I used the SFML library to load the ima...
