A very popular robot form factor these days is the self balancing robot. And the best example is the Segway personal transport with two horizontally mounted wheels.
But has anyone done a robot with two vertically mounted wheels, like a bicycle, that can stay upright? We went to find out.
It turns out that, YES, there are some cool robots with inline wheels! In the Youtube video above, Youtuber aoki2001 shows a great example. The large wheel where the rider would be is what makes sure the vehicle doesn’t topple over. It acts as an inverted pendulum, pushing against the large wheel’s inertia by rotating the motor to which it is attached.
But why use two wheels when you only need one? His unicycle version is below:
Consider building your next robotics project with Adafruit Crickit – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express that lets you #MakeRobotFriend using CircuitPython, MakeCode, or Arduino, to build robotics, arts, crafts, audio animatronics, sensors, agriculture/robot farming, physical computing, kinetic sculptures, science experiments, telescope control and much more!
Do you have a self balanced unicycle or bicycle? Post your experience and build in the comments!
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
