Matthew Borgatti has built an air-powered, 3D-printed robot tentacle that waves in a friendly fashion and lends a helping hand. It is in no way erotic. Nuh-uh, not at all.
Print Your Own Robot: Part 6
So, with a very nice looking tentacle in hand, it was time to start experimenting with robotic air control. I believe I’ve found a system that works in a pretty simple and straightforward way. It still needs some work when it comes to the programming end, but I think the mechanics are well sorted. The idea is to pulse air into the tentacle using a solenoid valve, and have a constant bleed on the line so that flex will entirely be controlled by how long the valve stays on. It’s sort of a low frequency PWM. I’d like to get this working using a visual interface in Processing but, given how little I program, progress has been slow. I’ve got a thread on Adafruit with what I’ve come up with. In the meanwhile, you might like to check a rough video of the trefoil inflating.
Businesses like Adobe Stock use large, visible watermarks to deter copyright infringement; a new paper presented by Google Researchers to the Computer Vision and Pattern Recognition shows that these watermarks can be reliably detected and undetectably erased by software.
CJ Hunt was at the neo-Nazi rally in Charlottesville when he spotted this young man in white supremacist uniform (white polo and khakis) running away from counterdemonstrators, then turning abruptly and stripping off while insisting that he was not really a Nazi and had just shown up for fun.
Jose writes, “I was offended by Trump’s speech to the Boy Scouts. It’s a slippery slope and seemed so reminiscent of the past. I synchronized Adolf to deliver Trump’s remarks to show how close we are to repeating the past. It’s an ode to Chaplin’s City Lights and The Great Dictator.”
