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.
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.

These toys and games can keep the kids busy while you’re all trapped inside. As rough as all this time cooped up inside the house is on us adults, it’s even worse for kids. All that borderline maniacal energy along with an unquenchable thirst for stimulation and attention make home sequestration like a life sentence […]
Python is everywhere. Just look under the hood of virtually every major tech player of the 21st century and you’re likely to find a whole lot of Python-based coding language staring back at you. Case in point: Netflix. You may not know it, but from its security protocols to its much-hyped recommendations, it turns out […]
