La definición de los parámetros de la matriz de Denavit-Hartenberg se establece con el diseño físico de una pata del robot. Para ello, se considera la pata como un manipulador serial de 2 grados de libertad, con juntas de rotación....
We are using two main embedded controllers. The ESP8266 and the STM32F446RET6. The ESP is going to do most of the 'heavy lifting' for this project. It will need to do over the air updates and manage the data coming in from the STM as well as upload this...
This is really a "Part 3" to the other two, but it doesn't have much to do with the modifications of the axis. This here is just a place to details the motors list, technically 3 types, and their specs in case someone wants to upgrade them. I'm also...
Sophi Kravitz : HI everyone, we're going to get started Sophi Kravitz : @Nick, welcome to the chat! Nick : Hello everyone! Sophi Kravitz : Can you introduce yourself and tell us a little about the kinds of things...
Today was an awesome day. I finally got linear motion working in both the X and Y direction. I also created a paint program in Python that can output its canvas to instructions for the 2D plotter. The end is getting closer!
So IBM Blue Mix had issues with Red Node all weekend and my app would not connect. I spent Sunday building one from scratch and that would not connect. So time is up. I will continue with this. Guess the apps still are not running this morning:The project...
After final assembly of the Reflow Oven, I knew I need to test and tune the PID parameters.The sample ARDUINO program provided by ROCKET SCREAM uses a few ARDUINO libraries; most notable are Brett Beauregard’s PID and Limor Fried’s (LadyAda) MAX6675...
Today I made to working order (very simple, no stability engineering) a joystick controlled x,y directed foot for a 2d 2 servo leg. (as pictured previously). I will post an 8 minute video below the code. I do have some trouble. If I move the foot outside...
I made the tape reading mechanism more reliable by weighting down the copper nails that serve as brushes. I also made a guide to prevent them from moving more than a half a millimetre or so out of position. This video shows the mechanism reading a card...
As a nebulously-defined “Hackaday advisory judge”, I want to try out advising folks on theirHackaday Prize entries. On our podcast, I offered to take a look at a project and score it as I would if I were doing the contest judging. William...
After we built Poorna, our base model, we had a bit of a problem. We had engineered a lot of flexibility into our design. Folks asked us, “what can you do with this?”. My typical response, invariably, would be “a lot – anything,...
Jasmine Brackett Hello Everyone. Welcome to this week's Hack Chat! !!!Bhavesh Kakwani WooShulie: Welcome!! We have tons of questions in our sheet already! https://docs.google.com/spreadsheets/d/1ZHahHN4kU0YBjMgrZMU9ntrmdDD8JOUmpHX2mR6Ok0w/edit#gid=0Jasmine...
Most CPUs contain some number of internal registers, a subset of which are available for programs to use. These are often not much more than very fast internal memory connected to internal bus(es) and ALU(s), meaning that the the transformation of bits...
