About

The Crow Bar is an interactive device tailored specifically for Corvids (although it can have other applications ,), aiming to lay the ground work for further research into their sensory perception and cognitive abilities.

The device is designed to not only facilitate in-depth study of Corvids but also to be user-friendly, inexpensive, and easily replicable for widespread application.

The proposed open-source design is meant to leverage Corvid’s remarkable curiosity and problem-solving abilities. The Design includes a two-step puzzle which acts as a threshold to discriminate other birds to interact with the device.

What you'll need

The Crow Bar is conceived as a fully modular and adaptive artefact. ,

  • Access to 1 Resin Printer
  • Access to 1 Filament Printer
  • Any Backboard
  • Gecko Tape
  • 1 Empty Bottle
  • 2 8x16x5 Ball Bearings
  • 6 M6x25 Screws
  • 1 M6x16 Screw
  • 7 M6 Washers
  • 6 M6 Nuts
  • 1 M8 Nuts
  • 2 M6xM10 Threaded Inserts

You are free to leave out any unwanted parts. Although the full version is designed to cater specifically to corvids, leaving out the puzzle components (door, rotary system) results in a lovely bird feeder.
