AQUA man: The rise of the six-limbed robot turtle

It has six rotating flippers and can walk along a shoreline, swim in open water or dive deep into the dark ocean.  It is not a toy or a character in a computer game, but an amphibious autonomous robot named AQUA.

“It’s a six legged robotic turtle,” says Michael Jenkin, a professor of Computer Science and Engineering at York University, whose work focuses on developing algorithms to enable AQUA to build and reason its position and orientation in a 3-D environment.

AQUA is part of a research project on autonomous vehicles being developed by researchers at York and McGill universities, to explore underwater environments and gather data with minimum disturbance to aquatic life. AQUA is primarily a research platform allowing scientists to ask fundamental and applied questions to autonomous systems.

“The fundamental question that we are trying to ask is, how do you build machine that can operate autonomously under complex environmental conditions,” says Jenkin.  “We are trying to answer questions that will allow us to build machines that will operate anywhere.”

AQUA is programmed to answer questions such as “Where am I?” and, “What is my orientation?” Jenkin says GPS systems help people navigate the Earth’s surface, but in more complex environments people have difficulty in orienting themselves.

“It is not very easy for scuba divers and pilots to know which way is up, because the internal systems that normally generate that information don’t work as well because of the complexities of the environment.”

Advanced robotic systems have begun to emerge as a key component in technology–based industries. As Jenkin points out there are cars that automatically stop when sensing danger and airbags that are triggered before impact.

Jenkin sees AQUA as a possible answer to solving problems that would normally require extreme measures.  Autonomous robots have the potential to help solve problems like monitoring oil pipelines. This would help streamline the current methods that require a multitude of components including using airplanes to take radar images.

AQUA is one of four amphibious autonomous robots on the planet. Although AQUA a research platform, versions of the robot have been used commercially. Jenkin’s last project involved developing a robot used to assist police in the investigation of crime scenes.

There is no timeline for how long AQUA can be used as a research platform. Robotic technology is rapidly advancing and it is only through continued research that scientists like Jenkin can remain on the cutting edge of robotics.

Michael Jenkin will be speaking next week at the What Matters Now event on April 9. This is a free public event scheduled from 6:30 p.m. to 9 p.m. at the McMichael Canadian Art Collection gallery.

Student studying

Who gets into university

Sharon Oosthoek | September 28, 2015

Nipissing University sociologist David Zarifa studies the educational and labour market experiences of disadvantaged youth, and he has good news and bad news. The good news: access to undergraduate education continues to increase for traditionally disadvantaged students, including those from low-income families or whose parents did not continue past high school. The bad news: at the higher levels — post-graduate and professional programs — the playing field is much less level. Zarifa came to this conclusion after a close examination of Statistics Canada’s National Graduate Survey of the year 2000 cohort. The survey looks at the experience of 35,000 undergraduates who completed various programs across all provinces and territories. Sociologists have long known that social origins can influence a student's educational experience, directly through parents’ level of education and indirectly through student performance, aspirations, and academic confidence. But there is very little research in Canada about how social origins influence professional or graduate school attendance. When Zarifa crunched the Statistics Canada numbers, he found nearly 35 per cent of undergrads whose parents had a master’s or doctorate degree entered a professional or graduate level program. That compares to only about 13 per cent of graduates whose parents did not have a postsecondary education. He also found about 21 per cent of graduates without government-sponsored student loans entered a graduate or professional program, compared to only about 14 per cent of graduates with loans above $15,000. Zarifa says he is discouraged to see parent education still has an impact at the graduate and professional level, even when taking into consideration other important factors such as academic abilities, aspirations and the educational experiences of graduates. "You would hope by the time students have their undergraduate degree, they wouldn't have this disadvantage in carrying on and trying to better their career prospects," he says. He hopes his study draws attention to some of the challenges facing groups from less privileged backgrounds: "While more and more students are continuing on into some form of postsecondary education, not all social groups are accessing the most lucrative segments within the postsecondary system equally."

Welcoming newcomers

Robyn Dugas | August 25, 2015

Most research into Canadian immigration focuses on its three largest cities: Toronto, Montreal and Vancouver. Yet mid-sized cities such as Ottawa are just as dependent on newcomers to maintain populations, boost local economies and offset labour shortages. “Canada’s approach to managing the admission of newcomers is undergoing a fundamental change," says Western University social psychologist Stelian Medianu. "In particular, the new system that is taking shape will lead to greater involvement by employers and by colleges and universities.” But in places such as Ottawa, these organizations may lack the infrastructure and tools to help integrate immigrants. The answer, says Medianu, is interagency collaboration. Settlement agencies have the expertise — so why not bring that expertise to employers, universities and colleges as they help immigrants transition to Canadian society? Connecting with the experts Medianu’s research is just one part of the Pathways to Prosperity Partnership, a nation-wide alliance of university, government and community partners researching the integration of immigrants and minorities in Canada. He is working with an umbrella group representing Ottawa's settlement organizations called Local Agencies Serving Immigrants (LASI) Coalition. With the coalition's help, Medianu is identifying the needs of each stakeholder group: employers, educational institutions, immigrants and international students. He is also researching the most successful initiatives around the world to determine which ones could be put to use in the Ottawa region. His work is part of a year-long Mitacs Accelerate internship. Mitacs is a national non-profit organization that supports research partnerships between universities and partner organizations. Medianu is identifying how each LASI-affiliated settlement group is uniquely suited to furthering immigrant integration. "Each settlement agency has its own capacity and expertise," he says.  "Together they can create suites of services that better match the needs of employers, educational institutions and newcomers.” With that information at hand, Medianu has been  mapping potential partnerships between these settlement groups and the companies and institutions that could benefit from their expertise. At the end of the project, he’ll provide LASI with recommendations and research results that will help its member organizations build fruitful partnerships in the community and, ultimately, provide a streamlined settlement experience for new Canadians in mid-sized cities.

Tracking turtles

Sharon Oosthoek | August 24, 2015

James Paterson spent the spring of 2009 and 2010 hiding behind trees and crouching in the underbrush of Algonquin Park. Thus camouflaged, he allowed himself an occasional peek as he waited patiently for turtles to lay their eggs in the woods. But as soon as they left, he would dash out with a screen to cover the nests and protect the eggs from predators. read more »

When exile drags on

Araina Bond | August 19, 2015

When James Milner visited Kenya's Dadaab refugee camps in November 2001, they had been in place for almost a decade.  The camps are now nearly 25 years old and their occupants — mostly Somalis fleeing civil war and drought — number 350,000, making the camps the largest refugee settlement in the world. read more »

Stories from the road

Katie Woodstock | August 17, 2015

Katie Woodstock is part of our Research Matters team touring the province this summer to spread the word about research breakthroughs at Ontario’s 21 publicly funded universities. This month’s theme of migration and long-distance travel is a good fit for the experience that Sarah, Alex, Badri and I have had this summer as we travel across the province to talk with people about why university research matters. So far, we’ve covered 10 cities and more than 10, 000 kilometres to promote game-changing discoveries, including insulin, Technicolor, and the Yukon Gold potato. It has been amazing to see the pride people feel in knowing just how many important innovations have come from this province. But these game-changers are just the tip of the iceberg when it comes to discoveries from Ontario universities. While we have been teaching people about the huge diversity and significance of Ontario university research, we have been learning the same lesson ourselves. One of the highlights of the summer has been the opportunity to speak with a huge variety of researchers about their work. We met a team in Gravenhurst that looks at whether turtles living near roads are more stressed, a researcher in London who looks at how music affects our memories and a researcher from Leamington who investigates the anti-cancer properties of dandelion roots. I have seen the wide impact that university research has had in this province, which is one of the many things making our long-distance journey this summer so worth it. Interested in chatting with us? Come to one of our upcoming events and test your knowledge with our fun trivia game. We hope to see you there!
