Watch a fin-propelled underwater robot prototype

Wednesday, November 25th, 2015


The robotic prototype swimming under water propelled by fins, it was developed at the Control Systems and Robotics Laboratory of the Technological Educational Institute of Crete, in Heraklion (Greece) and it’s controlled by an Arduino Mega:

Each fin is comprised of three individually actuated fin rays, which are interconnected by an elastic membrane. An on-board microcontroller generates the rays’ motion pattern that result in the fins’ undulations, through which propulsion is obtained. The prototype, which is fully untethered and energetically autonomous, also integrates an IMU/AHRS unit for navigation purposes, a wireless communication module, and an on-board video camera. The video contains footage from experiments conducted in a laboratory test tank to investigate closed loop motion control strategies, as well as footage from sea trials.

the Arduino runs a custom-developed real time firmware that implements two Central Pattern Generator (CPG) networks to generate the undulatory motion profile for the robot’s fins. The robot  contains a  7.4V lipo battery powering also a Bluetooth module for wireless communication and a video camera to record footage of the missions.

Monitoring falcons with intelligent nests

Monday, June 24th, 2013

horus - falcon

The Lesser Kestrel (Falco naumanni) is a small falcon at the center of HORUS, a project aiming to develop a system for automatic real-time monitoring of colonial falcons at Doñana Biological Station, a public Research Institute in Spain.

The falcons breed in nest-boxes on the window sills which the  research team converted into “smart nest-boxes”: they have sensors to identify the falcons entering the box using RFID tags, but also cameras and other equipment controlled by and Arduino Mega.

Space experiments for everyone: the ArduSat project

Tuesday, June 19th, 2012

ArduSat, which stands for “Arduino satellite”, is a recently kickstarted project that aims at developing an open platform usable to emulate space scientists:

Once launched, the ArduSat will be the first open platform allowing the general public to design and run their own space-based applications, games and experiments, steer the onboard cameras to take pictures on-demand, and even broadcast personalized messages back to Earth.

ArduSat will be equipped with several sensors (such as cameras, gyros, accelerometers, GPS and more) packed inside a small cube (the side will be approximately 10 cm long) that can be accessed through a set of Arduinos.

Once in orbit, the ArduSat will be accessible from the ground to flash the required firmware for the experiments and for getting back all the collected information. People interested in performing space experiments will have access to a ground replica of ArduSat explotable to test and debug their code before the actual deployment.

The project is very ambitious, and it is expected that such an open accessible space platform will have a considerable impact on how simple space experiments will be carried out in the forthcoming years, in the case of fundraising success.

You may find the Kickstarter page of the project here.

Some advances in aerial vehicles: bat-inspired smart wings

Wednesday, June 6th, 2012

Researchers from Centro de Automática y Robótica (Universidad Politécnica de Madrid) and from Brown University carried out a very deep research about the specific behavior of bat flight, whose ultimate goal is to replicate the capabilities of bat’s wings by means of an ad-hoc designed micro aerial vehicle (MAV).

From the home page of the project:

[...] this research is oriented towards the development of a biological inspired bat robot platform, that allows to reproduce the amazing maneuverability of these flying mammals. The highly maneuverability is achieved by reproducing the flapping and morphing capabilities of their wing-skeleton structure. This structure is composed by several joints and a membrane that generates the required lift forces to fly.

To mimmic the muscular system that moves the joints of the wing-bones, Shape Memory Alloys (SMA) NiTi wires are used as artificial-muscles. Several challenges in controlling this SMA-based actuation system are regarded in this research.

Chilean Teen Twitts About Earthquakes

Tuesday, August 2nd, 2011

Sebastian Alegria, a 14 years old Chilean teen created an earthquake warning system based on Arduino, an earthquake detector (bought for less 100 $) and an ethernet shield.

Alegria’s rudimentary yet effective system comes from having survived Chile’s own earthquakes last year and seeing the devastation that covered Japan earlier this year. Keen on finding an inexpensive solution for early earthquake detection, he rigged an Arduino and domestic earthquake detector to tweet seconds before detectable seismic activity. Tweeting from @AlarmaSismos, it has already successfully detected every major earthquake that could be felt from Santiago since May. And it’s piling on the Twitter followers.

Screen Your Genome Under $512, Open Sourcing Biology With OpenPCR

Thursday, July 7th, 2011

Most of people working in the field of biological or scientific research should greet the open hardware applications we are  witnessing in this age of Garage Science. From the Phduino to the DIY Oscilloscopes, through  STM (Scanning-Tunneling Electron Microscope), Arduino is getting used to prototype tools that used to be more expensive and possibly unavailable some years ago.

OpenPCR is an amazing project aimed to bring the genome analysis to a desktot experience. From the “What Is OpenPCR?” page:

What can you do with it?

Cool apps include:

  • DNA Sequencing – PCR is used to generate enough DNA for the sequencing run. You can have a look at some of your own genome!
  • DNA Barcoding – Determining the species based on DNA. Can be used to identify plants, screen for agricultural pests, investigate airplane bird strikes, and check that sushi is legit. What about testing your food to see if they contain GMOs (Genetically Modified Organisms)?

The Polymerase Chain Reaction, or PCR, is a method of replicating DNA. It is capable of taking a small amount of DNA, or even a single molecule, and amplifying (copying) a specific region exponentially, such that once the reaction is finished, there may exist up to 230 copies of each starting molecule (do the math — that’s more than a billion!).

This is important because DNA of interest often exists in quantities too small to detect, or may be mixed in with other DNA. For example, an accurate test for HIV must be able to detect a single virus particle in 50,000 cells. PCR is able to do this by targeting a small region of DNA that is specific to the HIV virus. If the virus exists in a sample, amplification will occur which can be easily detected. If no virus is present, no amplification will occur.

The specific region of targeted DNA is determined by how the reaction is setup, based on the specific “PCR primers” added to the reaction mixture. Virtually any sequence of DNA can be targeted.

if you still have some questions and / or want to know more about PCR have a look at this wonderful & explanatory graphics.

Plantduino Greenhouse Cares Of Your Plants While You’re Away

Monday, July 4th, 2011

Nice step-by-step guide to lets you set up a project that taked care of your field while you’re away:

This summer I wanted to combine my two loves of plant science and engineering. Thus I am constructing my very own greenhouse in my backyard. I am an undergrad, and as any former student knows, this means I move around constantly, and I am not always around to take care of my vegetable garden. I love my plants but since I am moving back to school in July, and my family is unreliable, I need a way to make sure that they are taken care of. Enter Arduino!

I have constructed an automated watering and temperature system. This includes sensors that will turn the systems on only when needed. This is essential when the ever-changing New England weather demands some intelligence in watering and heating patterns.

I want to document this project on Revolt Lab so that anyone who is also in love with vascular (or nonvascular) plants can join me and we can nerd out together! This is my first project using an Arduino so I am using wonderful articles from MAKE and Instructables as very helpful templates. Already the Instructables, MAKE, and Ladyada blogs have been ridiculously helpful so, worry not biology nerds, you too can show the engineers just how awesome we are!
