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. 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

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. 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.

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… Read More »4 Channel RF control on Arduino

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.The basic operation of a stepper motor and its advantages like position… Read More »Controlling multiple speed-independent stepper motors simultaneously with Arduino.

Akrep Crawler Robot | Cheap and easy telepresence project

The Akrep Crawler Robot it’s an “state of the art” project designed to test some design and constructions abilities on a fun context. The robot was designed on a simple crawler base, made by a rubber band over wood wheels, this to simplify the control to just 2 DC motors that ensure the movement over most surfaces. The telepresence module offers the ability to control the machine and explore the field remotely via Wi-Fi using a video streaming and a… Read More »Akrep Crawler Robot | Cheap and easy telepresence project

Infrared sensor test with ARDUINO

CNY70 reflective sensor is an infrared sersor allowing alteration of an analog electrical signal depending on the amount of infrared light that is reflected by an object near the sensor, in this way the sensor can be used as a switch or as a reader analog signal. There are two types of application, a proximity sensor and a tachometer. The proximity sensor is located perpendicular to a reflective surface which means that, at steady state there is always a high… Read More »Infrared sensor test with ARDUINO
