Pretty much everything @Pansenti these days ends up being battery powered and wearable in some way. And the Raspberry Pi is no exception. Kitted out with a LiPo battery, voltage regulator, WiFi dongle, Bluetooth dongle, GPS, IMU and 7 port USB hub it’s ready for anything.
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.
