Need a hug? Build a hug robot and get your fill! via instructables
Hugbot is a soft robot which gives small hugs. Its arms are made of custom 3D printed vertebrae and actuated by fishing wire which is threaded through the vertebrae to stepper motors controlled by an Arduino inside its body. Hugbot was born of an interest in making something soft and squishy which could move based on its outside environment.
They key to Hugbot is its arms, made of 3D printed joints with two strings running through them. Pulling one string or the other causes the arm to bend. Hugbot is simply two of these arms, each hooked up to a pulley on a stepper motor controlled by an Arduino Uno. A flex sensor in its head provides input for when the arms should open or close.
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
