Bionic Microrobot that Moves Like a Real Water Bug



A team of researchers from China managed to create an aquatic microrobot that moves almost like the Gerridae. The latter is a family of bugs also called water striders or water bugs. Just like the real water bugs, the tiny machine is able to move on top of the water's surface.

According to the researchers, their latest invention represents an improved version of previous robots. It can be used in military spy missions, monitoring water pollution and more.

The body of the bionic robot is about the size of a quarter, featuring 10 long water-repellent legs that extend from both sides of the body and used to keep the machine afloat. There are also 2 moveable short legs mounted at the center and powered by two tiny motors that allow the robot to move across the water's surface.

Despite the fact that the microrobot is much heavier than a water bug, it nevertheless can stand, walk and easily turn on the surface of the water.

It is worth mentioning that the research was funded by the Harbin Institute of Technology and the Natural Science Foundation of China. The research was published in the journal ACS Applied Materials & Interfaces.

WASP Drone - DIY Spy Plane Able to Intercept Phone Calls



Mike Tassey and Richard Perkins are two security experts who managed to create a unmanned flying vehicle called WASP drone. The name of the drone is short fro Wireless Aerial Surveillance Platform and it was developed to demonstrate how easy it is to fly overhead capturing Wi-Fi signals, intercepting cell phone calls, or initiating denial-of-service attacks.

The two researchers unveiled some of the possibilities of the new drone at the Black Hat security conference. The cost of the project is just $6000. Using this money the duo was able to turn a surplus U.S. Army target drone into an R/C spy aircraft that equipped with Wi-Fi and different hacking instruments like IMSI catcher and antenna. These tools are able to easily spoof a GSM cell tower and capture cell phone calls.

In addition, the drone that weights 14 pounds and is 6ft long includes a dictionary that boasts 340 million words. This tool is used to carry out exhaustive key search.

It would be interesting to note that at 2010 DefCon, English hacker Chris Paget demonstrated how to build a cell phone base station that can trick close by cell phones into transmitting their outbound calls via it and not commercial cell towers like they suppose to. In such a way it is possible to intercept phone calls.

The same technology is used in the drone. Despite the fact that the FAA regulations allow such vehicles to fly at an altitude not higher than 400 feet, it is quite enough to fly overhead without much noise.

In addition, using GPS coordinates and Google maps, it is possible to program the drone to fly a specified course. Still, remote control is needed to allow it to take off and land.

Although the security experts built their drone to show how easy it is for bad guys to accomplish their evil plans, the vehicle can be also used to help in various rescue operations - it could be equipped with infrared cameras and shape-recognition technology to search for lost hikers, for example

Solar-powered Electric Tricycle from Pakistani Student



The electric reverse tricycle (two wheels at the front and one at the back) built by Farrukh Khan, a designer from University of Engineering and Technology Lahore in Pakistan, is powered by solar energy and costs only $600.

Currently the student is still working on improving certain features of its trike, but soon the vehicle is expected to be launched onto the market.

The student managed to build his eco-friendly vehicle is just 18 days. Solaron measures 2.13 x 1.06 x 1.37 meters (7 x 3.5 x 4.5 ft) and weights 60 kg (132 pound). It includes a t-shaped framework made of aluminum mounted at the front, and the back part of the vehicle, behind the seating area, is made of an old bicycle frame.



In addition, the vehicle boasts a 40 watt photovoltaic canopy mounted above the rider. It was installed to charge the onboard 12v/80Ah dry cell solar battery that powers a 24 volts electric motor. The latter turns the back wheel through a chain and several sprockets.

According to the inventor, his vehicle can reach a top speed of 30 kph (20 mph) and travel about 70 km (43 miles) on a single charge. The whole project cost the young man PKR 46,670 ($540).



It would be interesting to note that the young inventor has developed a detailed guide on how to build such a vehicle. The instructions were posted online so people could build their own variant of a solar-powered tricycle.

Solar Electric Robot Chariot from Bob Schneevis



An inventor who became famous after creating the Dubya Bot Chariot has returned with an even more intriguing device - a Solar Electric Robot Chariot.

In the new design developed by the professional machinist Bob Schneevis, the robot chariot replaces the chariot driver. The invention was presented at the Maker Faire Bay Area.

By harnessing solar power the robot is able to move its two front legs to which rollerblades are attached with the back featuring two large wheels that keep the chariot rolling. It would be worth noting that solar energy is the main source of power for the machine.

The autonomous movement became possible thanks to cameras that ensure a safe and eco-friendly ride around a city.
