Right now, most of us take many everyday tasks for granted. Daily activities like brushing your teeth or making yourself breakfast seem simple, but they may be nearly impossible for people with physical impairments, including our growing elderly population. Goldie Nejat, associate professor in the Department of Mechanical and Industrial Engineering at the University of Toronto, is building healthcare robots to assist with these activities, allowing the elderly to live at home with greater independence, or giving a helping hand at long term care facilities.

Nejat is designing robots that can perform several tasks, and that can also interact with people, picking up on verbal instructions and even cues on the user’s emotions and intent. Pushing the envelope on autonomy and artificial intelligence, these robots must be aware of their environment and be able to react and adapt to new situations.

Nejat takes inspiration from the human brain, making decisions based on the latest research in psychology or human social behaviour sciences. In a way, programming robots helps us better understand people and problem solving.

Her interdisciplinary approach to robot design also includes collaborators in healthcare, occupational therapy, nursing, and even residents in long term care facilities. This valuable feedback allows her to tailor her designs to the wish lists of actual users.

Beyond assisting with daily activities, Nejat is also building robots that can help with emergency response. She explains that search and rescue robots can be useful after a natural disaster, such as an earthquake where “you have collapsed buildings, and you may have people trapped in those buildings. It may be dangerous for the rescue workers to just go into those buildings initially, because we don’t know what’s in there. So we can send robots, and the robots can search the area, map it out. If they find victims, they tag them on a map and say this is where they are, and provide that information to rescue workers so then they can go in and focus where their search will be, and they may know that there are no eminent dangers such as fires or gas leaks.”

Prof. Goldie Nejat is the Director of the Institute for Robotics and Mechatronics (IRM) and an Associate Professor in the Department of Mechanical & Industrial Engineering at the University of Toronto. She is also the Canada Research Chair in Robots for Society, the Founder and Director of the Autonomous Systems and Biomechatronics (ASBLab) Laboratory, and an Adjunct Scientist at the Toronto Rehabilitation Institute.

Prof. Nejat’s research focuses on developing intelligent service/personal robots and mechatronics systems for applications in health, elderly care, emergency response, search and rescue, security and surveillance, and manufacturing. Her research is leading the development of intelligent assistive robotic aids that can meet the challenges posed by an aging population. Prof. Nejat has over 100 international publications in both the natural and health sciences domains. She has been invited to speak about her research to scientists, engineers and healthcare professionals at many events around the world. She has served on the organizing and program committees of numerous international conferences on robotics, automation, human-robot interaction and medical devices. Professor Nejat is the 2013 recipient of the Engineers Canada Young Engineer Achievement Award and the 2012 Ontario Professional Engineers Young Engineer Medal. Her team’s work has been focused in numerous international and national media outlets including Time magazine, The Naked Scientists, the Globe and Mail, Reader’s Digest, Zoomer magazine, CBC’s the National and the Discovery Channel. In 2013, she was named by Toronto’s the Grid magazine as one of the top young scientists who is reshaping medicine.
