I say “partially” self-balancing because it only balances along one axis (forward/backward), and the rider still needs to balance left and right (it’s analagous to riding a bicycle “no hands”). It operates much like a Segway — you lean forward to accelerate, and lean back to brake. The top speed is about 15 mph, and it easily goes 5 miles on a single charge. This is my primary mode of transportation on the MIT campus.
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.
