Super fun project from last fall by maker bbtinkerer up on Hackster.io.
Simple and easy to build face following robot with off-the-shelf parts for anyone to create. No need for expensive or specialized tools such as 3D printers, CNC machines, or laser cutters. Most of the items you can easily order from Adafruit or Amazon and probably already have laying around.
The robot is basically a line following robot but instead of following a line, the robot will track to the faces it sees. Attach a container, box, basket, etc. to hold things. The robot then can be used to delivery bot. ChocoRobo likes to deliver chocolates to kids and make friends.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
