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.
Wait for it.
Carol from Cheapass Games writes, “In our continuing quest to bring back the very best classic Cheapass Games, we’re creating a new boxed set of Button Men, our strategy dice combat game. This time around, the characters will appear on cards, rather than pin-back buttons, but since they’re all 1950s era gangsters, the ‘button men’ […]
Mozak is a game where you score points for participating in the mass-scale, crowdsourced mapping of dendrites in scanned brains of humans, rodents, and other organisms.
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
