IoT/Edge Device 2.0 Robotic Experimentations (Arm)

January 18, 2026

More experimentation with robotics. This time a robotic arm, starting with a scooper, then a gripper.

Components of this build include: Adafruit Crickit HAT, Positional Servos (4x), Raspberry Pi 4B (4GB on-board memory) , USB 3.0 Boot, Various Lego Technic components, Cardboard, Paper, Tape.

I had to pivot my plans for the automation; I originally planned to attempt computer vision that would secure and move the payload, but I didn’t feel I have the tools in my toolkit to do that yet. There are many “micro-adjustments” that the arm needs to make to accomplish this and encoding that isn’t trivial.

Instead, for now, I pre-programmed “left” and “right” automations as you see in the later portion of the video. You can see in the tail end of both, how the the gripper nudges into the payload - this is the sort movement that a more advanced automation that adjusts dynamically might avoid. Something to potentially revisit after learning more about robotics.
