A robotic system designed to care for millions of biological samples in sub-zero temperatures has been chosen as a finalist for a top engineering award.
The Polar system is already used at the UK Biobank, a facility that aims to shed light on debilitating diseases.
The robot system will guard 10 million human blood and fluid samples at -80C for 25 years, whilst also allowing scientists to access them at any time.
It is one of four finalists which will compete for the annual MacRobert award.
The prize is given out by the UK’s Royal Academy of Engineering for technological and engineering innovation.
The other finalists are the first commercially available bionic hand, an advanced filter to remove soot from diesel engines and a tiny silicon sensor which can detect explosives or toxic chemicals.

The Polar system, designed by the Automation Partnership, consists of a series of ultra-low temperature compartments designed to hold blood and urine samples, which can be accessed automatically by robotic arms.
The liquid-nitrogen cooled store has been designed so that researchers do not have to enter a refrigerated area to retrieve or load samples.
It has been used by pharmaceutical companies as well as the UK Biobank, a medical research facility which intends to collect samples and data from more than 500,000 volunteers.
This will be used as tool by researchers investigating a range of life-threatening illnesses including cancer, heart disease and diabetes.
It already contains data from more than 100,000 volunteers.
It is one of three technologies with potential medical benefits that have been picked as finalists for this year’s awards.
A novel kind of chemical sensor, designed by Owlstone, a spin-out of Cambridge University, also has therapeutic uses.
The chemical chips are able to detect trace amounts of a wide variety of chemicals using a patented technique called Field Asymmetric Ion Mass Spectroscopy (FAIMS).
It fingerprints compounds by analysing how their charged forms move through a gas when subjected to electric fields. Each substance has its own characteristic signature.
The sensor can be reprogrammed to look for different chemical fingerprints, such as those found in pre combustion fumes during the initial stages of a fire.
However, one potential use is as a “breathalyser” to detect and diagnose illness by analysing chemicals on a patient’s breath.
It is known that asthma sufferers, those with cystic fibrosis and some forms of cancer breathe out chemical markers of their condition.
Researchers are developing mechanical mitts with better grip
No, we’re still not up to the level of Luke’s mechanical hand in Star Wars, but progress does seem to be accelerating. The i-LIMB, from Touch Bionics, debuted last year, and German researchers recently tested it against a new prototype, the Fluidhand. The researchers say both are more dexterous than the industry standard, given that the individual fingers of the mechanical hands can be controlled independently.
A patient at the Orthopedic University Hospital in Heidelberg tried out the i-LIMB and the Fluidhand, and found both to be an improvement over the other models. The battery-powered i-LIMB picks up muscle signals from the patient’s stump, and translates them into movement. The Fluidhand is powered by hydraulics, and reportedly makes it easier to grip and hold on to certain objects.
Apparently the patient gave the Fluidhand the edge, but it’s not marked for commercial production just yet.

MIT professor awarded for his innovative, human-powered irrigation pump
The Super MoneyMaker Pump—yes, that’s the real name—sucks up water from sources as many as 30 feet below the ground, can spray it up to 40 feet high, and can even push it through 1,000 feet of hose to cover a larger section of land. In all, the pump can irrigate two acres of land, and costs only around $100.
MIT professor Martin Fisher and his team at KickStart, a nonprofit, invented the pump for small-scale farmers. Since it’s human-powered and easy to use, it allows them to irrigate crops all year round, instead of just waiting for the rainy season.
And no, it’s not really about money-making in the American sense. It’s designed to help farmers start small businesses. At this point, the pump’s users are generating an average of $1,000 extra profit each year. A smaller, less expensive version is helping farmers clear $650 extra per year. The work is a reminder that great new technology doesn’t always have a chip at its core.
