Swarms of miniature robots, the future of surveillance and not only

novembre 2, 2009 Technology No Commenti


An international research project in several countries like Sweden, Spain, Germany and Italy is working on the development of microscopic robots, as small as insects, which in a near future might carry out several tasks if used in a group, wirelessly interconnected with each other.

The I-SWARM miniature robots (the acronym stands for Intelligent Small-World Autonomous Robots for Micro-manipulation) are based on a single chip, mounted on a 4-mm circuit board. Inside this single chip are installed the modules governing motion, communication with other robots and power saving.

All this is molded, by using a special conductive glue, on a flexible double-sided circuit board, which is folded in two thus doubling the available surface. The micro robot is powered by a solar cell located on the top, and movement is performed by three miniature legs, plus a fourth one working as a touch sensor.

By integrating tens or hundreds of micro robots among each other, making them communicate via infrared sensors, it is possible to program them as a whole group, setting them up to carry out complex tasks that a single robot would never be able to accomplish, such as, for example, cleaning of large surfaces, assembly or installation of micromechanical parts, and a whole lot of other jobs.

In a more distant future, a swarm of micro robots on which, along with the infrared sensor, one might install a micro camera, could be used for surveillance and monitoring operations on large sensitive areas, almost completely invisible for thieves or spies, who would certainly not be able to locate and destroy each and every robot.

Bug sweeping systems, to protect yourselves from prying ears

novembre 2, 2009 Technology No Commenti


As you may have seen on our pages several times, defense from telephone eavesdropping is one of the vital elements if we want to safeguard the privacy of our conversations, which translates to a better protection of our assets and our loved ones from any outside interference.

If on one hand, to make sure that no one can spy on your mobile phone conversations, we can recommend using an invisible mobile phone, the problem is a bit more complex when it comes to protect face to face conversations.

Unauthorized listeners might be aware of the content of our talks, by planting listening devices inside our office, concealing them in hidden corners, under a sofa pillow or behind a flower pot.

To make sure that our office and our home are really safe places, it may be worth using a bug sweeping system, which can expose any hidden microphones or transmitters, analyzing the radio frequency spectrum and detecting any source of transmission.

A bug sweeper works either by detecting radio signals, or by filling up the room with non-audible ultrasounds, which “cover” the conversations and make a spy operation useless, as the listener would only hear noise.

Of course, in all this, do not forget to protect your phone lines as well. For your office phone, you can use a scrambler or encrypted phone, which transmits its phone call using a 256-bit encoding key. In short, if you want to keep your conversations secure, thanks to Endoacustica you have several options to protect yourselves from prying ears and unauthorized listeners who may harm your business and your family.
