There’s no question that robots have come a long way since their cold, clunky, cumbersome inception. Nowadays they’re smart, agile and responsive — but they’re still missing the tactile, multipurpose elements that make living creatures flexible and autonomous. Until now. In a bid to make robots more lifelike, scientists have created a soft robotic lionfish and have pumped it full of life-giving “blood.”
While typical robots carry bulky single-purpose parts to provide power, such as a battery or gears, the newly-developed lionfish has a unique circulatory system that provides both power and propulsion. The “blood” pumped around the system comprises an electrolyte solution that acts as both hydraulic fluid and energy storage. The result? A more lifelike looking creature that was able to swim for long durations of up to 36 hours — eight times longer than a robot of similar design but without the synthetic blood.
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
