Smile, and the world smiles with you — or, in this case, a laser-cut flower running Android Things on a Raspberry Pi does.
The aim of the Expression Flower is to “challenge the perception of what robotics can be while exploring the possibility for a whimsical experience that is engaging, natural, and fun.”
The flower is powered by Google’s IoT platform Android Things, running on a Raspberry Pi, and it has a camera mounted in the centre. It identifies facial expressions using the ML Kit machine learning package, also from Google. The software categorises expressions, and responds with a specific action: smile at the flower, and it will open up its petals with a colourful light show; wink at it, and its petals will close up bashfully.
The build is made of laser-cut and 3D-printed parts, alongside off-the-shelf components. The entire build protocol, including video, parts, and code, is available on hackster.io, so all makers can give Expression Flower a go.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
