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.



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.

Controlling multiple speed-independent stepper motors simultaneously with Arduino.

Many robotic projects require the control of multiples digital and discrete outputs to work simultaneously, the motor interfaces are not an exception due big robotic instrumentation used today, the widespread Arduino control interface has the ability to handle steppers motors even with its own reference function librarys, but when it comes to a much more basic type of control over multiple speed's motors some arrangements need to be done.

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
