Very excited to share this new paper where we used AprilTags (a type of QR code) to study honey bees' foraging behavior. The system is completely open-access, cheap, and reproducible @robynlovesbees.bsky.social

x=red

rotation=blue
freeform physical slider feels interesting

Yep! recentering is simple as standing and pressing a button
The only way to get better tracking requires solid reference points (lighthouse, cameras, etc)
I've tried some of the jank budget ones (Kinect, AprilTags) and they're OK. Requires patience with tinkering to get right

I was trying to do realtime virtual production with A-Frame and AprilTags in 2018 which is kinda insane
I barely knew how to program in R at that point for my statistics class

Here's another video from an on-board camera running a different path. The software is looking for AprilTags and marking them. They're at fixed locations so the robot can (but currently isn't) use them to adjust the position it thinks it has on the field...

Hell yeah it did! The new software I'm working on will be able to do one-pass camera calibration using apriltags or multi-pass by moving the head and detecting the homing fiducial.

At this year's Montreal Robotics Summer School, teams programmed a Unitree Go1 to walk itself to dinner — sim2real RL, vision-based nav, AprilTags and all. Congrats to our Winning teams (5 & 6)! Full recap 👉 fracturedplane.com/blog/2026/08/31/MRSS2026.html

It's one of these for touch www.walmart.com/ip/43-inch-u... so it's just treating the paintbrush as a finger basically.
Mainly just exploring the possibilities of physical computing - there's more videos on feed.grantcuster.com including some older ones using touch and apriltags.

The ambition is to cram just enough C++ code into LabVIEW to get you from zero to a calibrated webcam, tracking Apriltags and rendering 3D objects with a single toolkit.
AR is a fun toy with useful applications in robotics and I hope that parts of the toolkit can be useful in other areas too.

oh yeah and the back legs also have touch tips and proxy control [so that you can kick stuff with them], but they use foot trackers which i currently don't have since I stopped using apriltags --

One of the biggest challenges in mobile eye-tracking is making sense of gaze in a dynamic reference frame. PyNeon lets you project gaze and fixations onto a surface using AprilTags, ArUco markers, or a visible contour, with all parameters fully exposed and customizable.

This is really dumb and way less effective than just a regular badge with a name on it, but I do have a counterproposal:
Instead of QR codes, we give them apriltags to accurately and easily track their positions and velocities with machine vision.
Link unrelated.

Ok, now I’m finding #Apriltags everywhere. Not only does Walmart have them on the walls for floor cleaning equipment navigation, but now on the products?
I’m guessing the candy was on a pallet and the tag was on one box to instruct the shipping - maybe.
