It’s Pi All the Way Down With This Pi-Powered Pi-Picking Robot

While most of us live in a world where the once ubiquitous Raspberry Pi is now as rare as hens’ teeth, there’s a magical place where they’ve got so many Pis that they needed to build a robotic dispenser to pick Pi orders. And to add insult to injury, they even built this magical machine using a Raspberry Pi. The horror.


This magical place? Australia, of course. There’s no date posted on the Pi Australia article linked above, but it does mention that there’s a Pi 4 Model B running the show, so that makes it at least recent-ish. Stock is stored in an array of tilted bins that a shuttle mechanism accesses via an X-Y gantry. The shuttle docks in front of a bin and uses a stepper-controlled finger to flip a box over the lip holding them in its bin. Once in the shuttle, the order is transported to an array of output bins, where a servo operates a flap to unceremoniously dump the product out for packing and shipping. There’s a video of a full cycle below, but a word of warning — the stepper motors on the X-Y gantry really scream, so you might want to lower the volume.


The article goes into more detail on not only the construction of “Bishop” — named after the heroic synthetic organism from Aliens — but also the challenges faced during construction. It turns out that even when you try to use gravity to simplify a system like this, things can go awry very easily. There’s also a fair bit of detail on the software, which surprisingly centers around LinuxCNC. And there are plans to take this further, with another bot to do the packing, s ..
