People With Limited Mobility Can Now Use Amazon Alexa to Control Exoskeletons

One of the challenges that comes with engineering exoskeletons that compensate for limited mobility is giving control to the people who wear them. Some systems use hand controls, while others can detect faint signals in the wearer’s muscles and respond accordingly. Now one exoskeleton startup is taking advantage of a technology that’s become mainstream in recent years: voice recognition.

As Engadget reports, Bionik Laboratories has integrated Amazon’s Alexa into its ARKE lower-body exoskeleton. The apparatus is designed for people with spinal chord damage or a history of stroke or traumatic brain injury that has hindered their movement below the waist. After strapping into the suit, wearers will now be able to use it just as they would a television set or stereo enabled with Alexa. Saying “Alexa, I’m ready to stand,” brings the joints to an upright position, and the command “Alexa, I’m ready to walk” prompts the legs to move forward. An Amazon Echo device must be within hearing range for the voice control to work, so in its current state the exoskeleton is only good for making short trips within the home.

Compatibility with Alexa isn’t the only modern feature Bionik worked into the design. The company also claims that ARKE is the first exoskeleton with integrated tablet control. That means if users wish to adjust their suit manually, they can do so by typing commands into a wireless touchpad. The tablet also records information that physical therapists can use to make more informed decisions when treating the patient.

Before the ARKE suit can be made available to consumers, it must first undergo clinical trials and receive approval from the FDA. If the tests go as planned Bionik hopes to have a commercial version of the product ready by 2019.

History
The Queen of Code: Remembering Grace Hopper
By Lynn Gilbert, CC BY-SA 4.0, Wikimedia Commons

Grace Hopper was a computing pioneer. She coined the term "computer bug" after finding a moth stuck inside Harvard's Mark II computer in 1947 (which in turn led to the term "debug," meaning solving problems in computer code). She did the foundational work that led to the COBOL programming language, used in mission-critical computing systems for decades (including today). She worked in World War II using very early computers to help end the war. When she retired from the U.S. Navy at age 79, she was the oldest active-duty commissioned officer in the service. Hopper, who was born on this day in 1906, is a hero of computing and a brilliant role model, but not many people know her story.

In this short documentary from FiveThirtyEight, directed by Gillian Jacobs, we learned about Grace Hopper from several biographers, archival photographs, and footage of her speaking in her later years. If you've never heard of Grace Hopper, or you're even vaguely interested in the history of computing or women in computing, this is a must-watch:

Watch Christmas Island’s Annual Crab Migration on Google Street View

Google

Every year, the 45 million or so red crabs on the remote Australian territory of Christmas Island migrate en masse from their forest burrows down to the ocean to mate, and so the female crabs can release their eggs into the sea to hatch. The migration starts during the fall, and the number of crabs on the beach often peaks in December. This year, you don’t have to be on Christmas Island to witness the spectacular crustacean event, as New Atlas reports. You can see it on Google Street View.

Watching the sheer density of crabs scuttling across roads, boardwalks, and beaches is a rare visual treat. According to the Google blog, this year’s crabtacular finale is forecasted for December 16, and Parks Australia crab expert Alasdair Grigg will be there with the Street View Trekker to capture it. That is likely to be the day when crab populations on the beaches will be at their peak, giving you the best view of the action.

Google Street View is already a repository for a number of armchair travel experiences. You can digitally explore remote locations in Antarctica, recreations of ancient cities, and even the International Space Station. You can essentially see the whole world without ever logging off your computer.

Sadly, because Street View isn’t live, you won’t be able to see the migration as it happens. The image collection won’t be available until sometime in early 2018. But it’ll be worth the wait, we promise. For a sneak preview, watch Parks Australia’s video of the 2012 event here.
