This article is the last in the series dedicated to building the Octopussy martial arts and self-defence training sparring robot. Here, I will explain the use of the software to control the device, which allows you to design a virtually unlimited range of training routines within the robot's features.

This article is the second one on the Octopussy training sparring robot for self-defence and martial arts. Here, I will explain how to build the electronics of the invention. The task consists of little more than connecting a few wires, although a tin soldering iron would also be convenient to have at hand to finish the job better.

I will show in this series of articles how to build a self-defence and martial arts training robot. I have named Octopussy to the invention since you can put several limbs to simulate different types of punches and kicks directed to all of the body parts. It is controlled by a computer, an Arduino board, and an application. I also provide the application source code for you to make modifications as you want.

With this article I finish the series dedicated to the ThiefWatcher solution, a homemade video surveillance system that is triggered when some intruder enter your home, alerts you by calling to the mobile phone and allows you to obtain at the moment pictures that you can use to help the police quickly identify the thieves and increase the chances of quickly recovering your stolen belongings. In this last article I will explain the App that is used as a remote client of the system.

In this second article in the series on the ThiefWatcher homemade video surveillance system, I will explain the different protocols that the application uses to interact with its different components, which can be replaced by different new ones allowing a large number of combinations. There is a protocol to communicate with the camera, another to trigger the system, another to alerting the user remotely, and, finally, a protocol to exchange photographs and messages to manage the server from client devices.

In this series of articles I will do a bit of DIY to build a video surveillance and alarm system against home thefts, using relatively cheap materials and a program that will notify to your mobile phone in case of detecting intruders and allow you to take photographs of them to be able to immediately notify the police and provide them those photos. Rapid identification of thieves can be crucial for you to recover all our possessions quickly.

A stepper motor is a kind of motor that, instead of rotating continuously in one direction, allows rotate in very small steps and stop and change direction very quickly, without problems of inertia. This makes these engines very suitable for mounting them in devices which perform movements that required high precision. In this article I will show how to build a simple controller to handle one of these motors through the Arduino board, along with a sample program written in CSharp that allows you to operate the motor from the computer where the plate is connected.

The Arduino boards, with lots of analog and digital inputs and outputs, allow us to control electronic devices from a computer through an USB interface with a very simple programming using a language similar to C. There are lots of prefabricated modules for controlling motors, relays and all kinds of sensors, but, if you like electronics, like me, you can design and connect your own analog or digital circuits.
