We sat down for an interview on the annual 2023 Higher Certain convention on AI that’s held in Edmonton, AB and hosted by Amii (Alberta Machine Intelligence Institute).
What initially attracted you to pc science?
So, after I got here again to highschool, I needed to really be a health care provider to start with. And work-life steadiness is basically essential to me, so I might spend plenty of time with my household. And I’ve at all times needed to simply assist folks, and I ended up taking a pc science class in my first yr of college, and it simply felt like such an incredible instrument that you could possibly use to resolve issues. And I simply fell in love with drawback fixing and determined that with the ability to work within the area of assistive expertise the place I might put that drawback fixing to make use of and really assist folks within the course of was the place I needed to exist.
How did you determine that assistive expertise was your ardour to get into?
I took a robotics class in my undergrad, and it was the place we used Lego Mindstorm kits with a purpose to be taught the fundamentals of mechatronics and robotics. And it simply all clicked collectively that it was a lot enjoyable to work with, and you could possibly write packages after which instantly see the outcomes of it. So, it simply made sense to merge my love of working with these robotics methods with my want to assist folks. Assistive expertise simply suits precisely into that area.
Might you outline mechatronics for our viewers?
It might be similar to something contained in the robotics sphere the place you will have these {hardware} methods, and you’ll management them with a purpose to enact change within the setting.
What are a number of the totally different use circumstances you have labored on for that expertise?
Proper now, I am working within the Blink Lab with Patrick (pilarsky), and the primary use case there may be I am engaged on higher limb prosthetics. So, we have now these good robotic gadgets that you could management by way of myoelectric indicators, and that might be the primary use case is how will we management these prosthetic limbs that are actually hooked up to the human physique with a purpose to do what the consumer needs.
How lengthy have you ever been engaged on that particularly?
I simply began my PhD in January. I did my grasp’s within the robotics and pc imaginative and prescient group on the College of Alberta, the place I labored on robotic manipulation with robotic arms.
I am simply now venturing into the world of prosthetics.
What are some security considerations that you’d say with the expertise in the intervening time?
With these good prosthetic gadgets, we at all times maintain security first and forefront. That is at all times what we take into consideration first, as a result of these gadgets are hooked up to a human. So, on the finish of the day, the gadget does not have the ultimate say. The human is at all times in full management. We will make ideas to the human, say, “I feel that you just need to do that,” however they at all times have the ultimate management over what occurs. So, we’re at all times occupied with what’s the security of the person who’s going to be utilizing these gadgets.
In a earlier interview, Patrick was speaking about how normally the mind has to be taught to adapt to the gadget, however on this case the gadget makes use of machine studying to adapt to the mind. Might you talk about your views on this?
Sure. So, we need to construct continuous studying methods for working on these gadgets. So, it is all about mapping the indicators from the consumer, which in our case can be EMG indicators. So, floor EMGs, you set electrodes on the person’s residual muscle tissues that they’ve, after which what do you do with these enter indicators? So, we need to map it to robotic movement, proper? Would you like hand open? Would you like hand closed? First we have now to determine how we’re doing that mapping drawback, and that is the place machine studying comes into play.
You might have sample recognition methods, so we will predict what’s going on with the precise muscle activation. We would like it to repeatedly be taught and adapt over time. You may assume that, say, your muscle tissues proper now. In the event you have been to go to the fitness center, your muscle form modifications. So, do we have now to now fully practice a brand new machine studying mannequin? No. We would like the gadget and the machine studying parts to adapt to the individual over time as they undergo modifications or as their intent modifications.
What sort of timeline do you assume it will be till we see these out in the true world?
I hope inside my PhD. That’s my purpose is to resolve this management drawback for higher limb prosthesis.
That may be superb. And what’s your imaginative and prescient for the way forward for assisted robotics, for example in a 10-year timeline or 20-year timeline?
I envision a world the place people that wish to have a prosthetic limb to be used of their on a regular basis life would be capable to use it in a means that we use our arms. So, to make it dependable, make it intuitive, make it simple to make use of, that is what I would really like for.
And do you see a customized future the place a smaller individual would have a smaller prosthetic? Or do you assume they’d be all the identical?
No, completely. I feel for one thing as private as this, you need these gadgets to really feel as an extension of your personal physique. Proper? You need it to be part of you. So, that brings us all the way down to customized and individualized healthcare. These prosthetic limbs would should be formed and tailored to the person who’s going to be utilizing them, a minimum of for my part. We already see this. Proper now, whenever you go to, say, the Glenrose Rehabilitation Hospital right here in Edmonton, and also you’re getting match for a brand new prostheses, they take 3D modeling of your residual limb, they usually personalize the customized match of your prosthetic limb to you. So, we’re already seeing this occur, and for these good gadgets, it will simply be much more so.
So, it will be customized 3D printed, most likely, for the consumer.
Yeah, customized 3D printed, customized match, after which customized customized management methods, additionally.
And the way lengthy does it take for a consumer to learn to use one among these methods?
Our purpose is that we’d be capable to practice a extra generalized machine studying mannequin, after which be capable to individualize it to the individual inside a 5, 10 minute coaching session. That may be a purpose of ours.
As soon as you have achieved this, what would you wish to work on subsequent?
An enormous a part of my analysis can be working with the anatomy division on the College of Alberta, And I’m fully fascinated with how we, as people, manipulate the world round us. So, every part to do with the human higher limb. So, our arms and our arms are fully fascinating. So, I wish to focus all my efforts on higher limb prosthesis and actually making these gadgets usable for folks in the true world.
In what methods is it more difficult than the decrease limbs?
The decrease limb, the movement may be very repetitive. In the event you consider our strolling gate, it is a neater management drawback to resolve. Whereas, for the higher limb, you want to have the ability to manipulate objects in 3D area, you will have so many extra levels of freedom. If you concentrate on it, if we shut our eyes and we attain round, we will nonetheless see the world round us by way of our arms. So, we have now these superb sensory organs that we will use to discover the setting. So, to have the ability to give that again to the medical group by way of prosthetic limbs, I feel, can be a superb,
Are you able to share the way you draw inspiration from anatomical research
I have been working with Dr. Pierre Lemelin within the anatomy division on the College of Alberta for the previous 5 years now. I am hoping that by way of the examine of human anatomy and understanding precisely how we manipulate objects within the setting, what are our nerve pathways, what muscle tissues are activated, we will use that information with a purpose to not simply enhance, to start with, the construction of prosthetic limbs.
Are there small locations within the precise design of the prosthetic limb that we will change that might be a small little tweak in mechanical design, however see an enormous enhance in operate? But in addition, the underlying management methods, how we use it. If we will perceive precisely which nerves are firing, after we’re considering, “Oh, open my hand,” then can we use that with a purpose to predict what the consumer needs to do with their prosthetic limb, after which enact that movement within the robotic gadget.
Thanks for the superb interview, readers who want to be taught extra ought to go to the next assets:
