OZER Hexapod V-0.1 Open-Hardware, modular 3D printed robot using Raspberry Pi

OZER is a work in progress to develop a totally functional hexapod for exploring functions on unstructured terrains. Keeping as main objectives the development of a low cost, easy to construct, assemble and operate structure which allows the reconfiguring of the platform for new uses.

Raspberry Pi: Configuring SSH, VNC and Camera Module Streaming

This tutorial resume common steps to setup a basic connection for a Raspberry Pi board to the net using SSH, VNC and video streaming from a camera module. Most of this information is broadly available on the internet with this article being a review to easy and particular implementation.

Prepariong the Raspberry Pi

Basic setup:

Arduino with RF module, custom data transmission.

Some usual RF devices are those digital modules where a button or command generates an digital output on the receptor, this limits the amount of control that can be generated on the receptor to a few "channels". In most cases some "complex" custom comunication is required, where the RF modules need to handle any type and size of information the process require.

4 Channel RF control on Arduino

RF modules offer the capability to wirless transmite datta on electronic and robotics projects, this modules are extremly easy to use and are quite cheap (about $5 USD) wich make them ideal for projects

In this little example an Arduino UNO board with 2 micro servo motors will be controlled remotely using an XY-DJM-5V SC2272-M4 RF controller. Note that this module is intended for be used as a simple relay on its digital pins, other modules allow more deep radio frequency communication.

External Incompressible 3D flow CFD Analysis OpenFOAM Tutorial

The case represent a kilo-class submarine totally submerged under a water medium. The interest data for this tutorial is the flow path over the submarine shape and how the water interacts, the pressure points on the structure and the turbulence generated.

Simple analog and digital control prototype using Arduino and Python

Building hardware interfaces for programs and robotic projects its always easy with Arduino, the communication capability of the board allows to send data directly to a computer or logic circuit with no need for complex custom electronic configurations. The prototype was created to test the following capabilities and characteristics for Arduino and Python working in together:

  • Arduino analog and digital read
  • Arduino Serial communication 
  • Python Serial port reading
  • Python periferical control emulation

LM-Plot Serial Devices Plotting Program

LM-Plot it's a simple and easy to use program intended to be a useful tool for electronic and robotic projects where common data analysis is required on real time samples, using the serial port to catch data the user choose to plot immediately the variable or record the data streaming into a permanent file. The program also allows to configure some plot settings in order to improve understanding, presentation and data storing for later interpretation.

Common subjection parts | Free library 1

In almost all design assemblies the use of subjection parts is imperative, the correct selection of this elements highly affect the process of manufacture and real world assembly. Thinking in a low costs, highly maintainable, standard desing could be the diference between a failure and a succes project.

This is a little Free Library of common subjection parts that can be used in any project.
