This is the second self-balancing board by this youtuber -the
first one used a single wheel and motor, while this model uses two wheels and two motors for tighter turning. He wrote an
Instructable about the process of building the first model (which is where I found this gem), and
his site is full of useful stuff for anyone interested in building their own (like me...).
Based on the same concepts that make Segways work, the brain of this machine is an ATMega 32 development board, complemented with a Gyroscope and Accelerometer to detect the surface tilt. The source code his ATMega is running is also posted on his website.
He uses a wireless hand-held remote to control steering in this video, but he's since gone back to a wired remote made from a hacked up Nintendo Wii Nunchuk.
In the *future, we will all have *wheels.

but make it work without a remote, like a segway and i'll be properly impressed
jubuttibsays...According to wiki the Segway turns around using the handle bar, only forward and backward movement is possible just leaning, same as this thing. So it already does the same things the Segway does without external controls.
MarineGunrockDumb. This would be so much cheaper and energy efficient if you just put four fucking wheels on it.
kageninsays...The remote is a safety mechanism - when you stop pressing a button, the motor dies; this is sometimes called a Dead Man switch, and is rather crucial in the design.

Building a "teeter-bot" is a common entry-level robotics project - you have to program up a "brain" that reads sensor data (the gyro/accelerometer), and reacts to the data accordingly. Depending on scale, you could spend about a grand doing it all from scratch. This builder had the mindset of "if I'm spending that kind of money on a robotics project, it'd be nice if I could at least ride it." And I'm inclined to agree with that mindset.
MarineGunrockI'm talking more along the lines of a segway mindset.
