One thing exoskeletons have done right is help with motor rehabilitation. Of course, their size and weight have decreased over time, but most of those available are suitable for rehabilitation, load-bearing assistance, and similar purposes. However, they are not designed for daily wear. Not concentrating on the lower limb, which is a saturated market, a duo of budding South Korean designers has targeted the upper limb; creating a wearable robot that can be worn for daily usage.
It’s called the Sleev. For now, it’s not far beyond the drawing books, but from how and what it’s projected to be built for, its God damn great solution for the purpose. Sleev is designed as a daily upper-limb exosuit (wearable robot). It supports independent arm movement and is effortless to wear and remove: just one hand, no more!
Designers: Youngha Rho and Sungchan Ko
It’s not that we are seeing a robotic assistant for the arm for the first time. The market is flooded with iterations of bulky and inconvenient wearable robots that are designed with a great level of technological input and robotic sensors, but somehow make the wearer feel like a cyborg. With its sleek and lightweight limb, the Sleev is conceptualized to change that for a robotic assistant that you would like to wear. It can be strapped on like any other elbow brace to provide assistance in its movement. In addition to being a crucial option for people recovering from stroke or sports injury, the Sleev (for its design and attractive appearance) will augment daily tasks like lifting and carrying; you will like wearing it when carrying a baby for a long time or doing groceries and have a lot of packets to carry back home.
As a wearable robot conceptualized to integrate exoskeletons into our daily life, the Sleev is also strong and intelligent enough to support with rehabilitation activities. To ensure this, the design is integrated with FMG (force myography), a method that detects movement intentions through muscle pressure. The muscle pressure is different in people based on their gender, height, weight, and age. So, for the data accuracy and for the correct functioning of the wearable robot, this information about the users will be necessary. And a larger database will ensure better results, the designers believe.
Collaborating FMG with IMU sensors, the designers suggest, they can allow the algorithm to know where the user intends to move and help them with it accordingly. Both these sensors are affordable and commonly used in game controllers, so they should not be overly expensive when Sleev can find itself into mass production. Interestingly, it relates its movements based on muscle strength and intention. The Sleev doesn’t need to be worn directly on the skin; users can wear it over a thin innerwear as well and go on with it during their daily activities.
