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. In this version (V-0.1) the robot is able to perform basic operations such as standing, and walking; the control set is command through SSH connection with a feedback video feed form the Raspberry Pi camera… Read More »OZER Hexapod V-0.1 Open-Hardware, modular 3D printed robot using Raspberry Pi

Here some essential servo motors used for robotics, aeromodelling and an RF device:
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. In this case an Arduino board connected to a RF transmitter that send the strings it recives via… Read More »Arduino with RF module, custom data transmission.
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… Read More »4 Channel RF control on Arduino
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.
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 Creating a custom shield for the control make… Read More »Simple analog and digital control prototype using Arduino and Python
