Meet MiRO: The robot dog with a mind of its own

Attendees of the International Conference on Robotics and Automation will this week meet MiRO: the robotic pet dog that has been built to provide the elderly with company.

MiRO – designed by Consequential Robotics – looks and behaves like a pet dog, and has six ‘senses’ including touch sensitivity, light sensitivity, stereo eyesight and sharp hearing.

The robot dog uses a sonar sense, like bats and dolphins, to help navigate its surroundings, and MiRO’s cliff sensors help to ensure that it does not fall off a table or down a flight of stairs.

“At the heart of our approach is human-centred design – understanding the practical needs of our users as well as their emotional wants and dreams,” said designer, Sebastian Conran.

Consequential Robotics is the result of a collaboration between the award-winning designer Sebastian Conran, as well as Professor Tony Prescott and Dr Ben Mitchinson from the University of Sheffield.

The company’s main focus will be to develop companion and assistive robotic systems that will enhance quality of life for people as they age.

Professor Tony Prescott said: “Consequential Robotics builds on a scientific approach to robot design that we have been developing in Sheffield for more than two decades and that is based on our understanding natural intelligence in animals and people.  We use ideas from psychology and neuroscience to help design future robots to be more useful and more life-like.”

“MiRO, our first product, is a step towards developing companion robots – the future robots that will share our personal spaces, provide entertainment and social interaction, and enhance our quality of life,” said Prescott.

Although the long-term plan is for MiRO to be a companion robot, initially the robot will be marketed to researchers who are interested in developing companion robots and to universities doing research in robotics or offering training in robot programming.

““Consequential Robotics addresses one of the fast growing emerging markets – companion and assistive robotics – thanks to its unique capability of combining world-leading psychology research with renowned award-winning design,” said  Aidong Xu, director of New Business & Partnerships at IP Group, the University of Sheffield’s intellectual property commercialisation partner.

Adding stem cells to the brains of mice “slowed or reversed” ageing

Albert Einstein College of Medicine scientists “slowed or reversed” ageing in mice by injecting stem cells into their brains.

The study, published online in the journal Nature, saw the scientists implant stem cells into mice’s hypothalamus, which caused molecules called microRNAs (miRNAs) to be released.

The miRNA molecules were then extracted from the hypothalamic stem cells and injected into the cerebrospinal fluid of two groups of mice: middle-aged mice whose hypothalamic stem cells had been destroyed and normal middle-aged mice.

This treatment significantly slowed aging in both groups of animals as measured by tissue analysis and behavioural testing that involved assessing changes in the animals’ muscle endurance, coordination, social behaviour and cognitive ability.

“Our research shows that the number of hypothalamic neural stem cells naturally declines over the life of the animal, and this decline accelerates aging,” said senior author Dongsheng Cai, M.D., Ph.D., professor of molecular pharmacology at Einstein.

“But we also found that the effects of this loss are not irreversible. By replenishing these stem cells or the molecules they produce, it’s possible to slow and even reverse various aspects of aging throughout the body.”

To reach the conclusion that stem cells in the hypothalamus held the key to aging, the scientists first looked at the fate cells in the hypothalamus as healthy mice got older.

The number of hypothalamic stem cells began to diminish when the mice reached about 10 months, which is several months before the usual signs of aging start appearing. “By old age—about two years of age in mice—most of those cells were gone,” said Dr. Cai.

The researchers next wanted to learn whether this progressive loss of stem cells was actually causing aging and was not just associated with it.

To do this, the scientists observed what happened when they selectively disrupted the hypothalamic stem cells in middle-aged mice.

“This disruption greatly accelerated aging compared with control mice, and those animals with disrupted stem cells died earlier than normal,” said Dr. Cai.

Finally, to work out whther adding stem cells to the hypothalamus counteracted ageing, the scientists injected hypothalamic stem cells into the brains of middle-aged mice whose stem cells had been destroyed as well as into the brains of normal old mice.

In both groups of animals, the treatment slowed or reversed various measures of aging.

The scientists are now trying to identify the particular populations of microRNAs that are responsible for the anti-aging effects seen in mice, which is perhaps the first step toward slowing the aging process and successfully treating age-related diseases in humans.

Self-driving delivery cars coming to UK roads by 2018

A driverless vehicle designed to deliver goods to UK homes is set to take to the road next year after the successful conclusion of an equity crowdfunding campaign.

Developed by engineers at The University of Aberystwyth-based startup The Academy of Robotics, the vehicle, Kar-Go, is road-legal, and capable of driving on roads without any specific markings without human intervention.

Kar-Go has successfully raised £321,000 through Crowdcube – 107% of its goal – meaning the company now has the funds to build its first commercially ready vehicles. This amount will also, according to William Sachiti, Academy of Robotics founder and CEO, be matched by “one of the largest tech companies” in the world.

The Academy of Robotics has already built and tested a prototype version of Kar-Go, and is working with UK car manufacturer Pilgrim to produce the fully street-legal version.

The duo has already gained legal approval from the UK government’s Centre for Autonomous Vehicles, meaning the cars will be able to immediately operate on UK roads once built.

The aim of Kar-Go is to partner with suppliers of everyday consumer goods to significantly reduce the cost of deliveries, and the company’s goal in this area is ambitious: Sachiti believes Kar-Go could reduce delivery costs by as much as 98%.

Whether companies go for the offering remains to be seen, but the company says it is in early stage discussions with several of the largest fast-moving consumer goods companies in Europe, which would likely include the corporations behind some of the most recognisable brands found in UK supermarkets.

While some will be sceptical, Sachiti is keen to drive the company to success, and already has an impressive track record in future-focused business development. He previously founded Clever Bins – the solar powered digital advertising bins found in many of the nation’s cities – and digital concierge service MyCityVenue – now part of SecretEscapes.

“As a CEO, it is one of my primary duties to make sure Kar-go remains a fantastic investment, this can only be achieved by our team producing spectacular results. We can’t wait to show the world what we produce,” he said.

“We have a stellar team who are excited to have begun working on what we believe will probably be the best autonomous delivery vehicle in the world. For instance, our multi-award winning lead vehicle designer is part of the World Championship winning Brabham Formula One design team, and also spent years as a Design Engineer at McLaren.”
