I am continuously impressed with how creative people are, and Kaisar (@roboticbits on Twitter) is the newest person on top of the list after creating "Dot," a stamp-sized two wheel robot. The robot is based on the Pimoroni Tiny 2040, and uses a 3V DC motor and a 70mA battery for power.

Kaisar claims that this is the smallest fully-functioning robot in the world, and while that might (or might not) be the case, either way it's an impressive build.

While not available quite yet, Kaisar has stated on Twitter that details will be posted to Github in the near future.

Kaisar has another mini-robot project called Pica, which is an impressive three-wheeled robot built on a cut out Raspberry Pi Pico, with three motors controlled by a TI DRV8833 motor driver.

Keep track of all of Kaisar's new projects by following their Twitter account @roboticbits.

This Kickstarter has passed its goal but users can still preorder.

The Raspberry Pi Pico is the first official microcontroller to come from the Raspberry Pi Foundation and like the SBCs that came before it, the Pico is compatible with a variety of HATs from third party developers. Today we’ve got an exciting new barcode scanning Pico HAT and Barcode Scanner Breakout to share with you created by maker Om Singh. Om recently created a Kickstarter that has more than surpassed its initial goal, ensuring the new boards are well on their way to development. The HAT is designed to mount to the Pico while the breakout can connect to devices via microUSB. Both provide a variety of tools to both scan and process various barcodes.
