Researchers from Université de Sherbrooke in Canada have engineered a waist-mounted remote controlled hydraulic arm can smash through walls. Here’s more from IEEE:
This type of wearable robotic arm is known as a supernumerary robotic arm. The system created by the Canadian researchers (in partnership with Exonetik) has 3 degrees of freedom and is hydraulic, actuated by magnetorheological clutches and hydrostatic transmissions with the goal of “mimicking the performance of a human arm in a multitude of industrial and domestic applications.” Like wall punching. The hydraulic system provides comparatively high power, but the power system itself is connected to the user through a tether, minimizing how much mass the user has to actually wear (and keeping the inertia of the arm low) while also limiting mobility somewhat. Off-board power does put a bit of a dampener on the superhero potential, but in practical terms, users aren’t likely to be moving around all that much, and if they are, mobile options could include being tethered to an autonomous vehicle that follows you around or perhaps, eventually, a more portable backpack power unit.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
