The Wheelbot: A jumping reaction wheel unicycle

Combining off-the-shelf components with 3D-printing, the Wheelbot is a symmetric reaction wheel unicycle that can jump onto its wheels from any initial position. With non-holonomic and under-actuated dynamics, as well as two coupled unstable degrees of freedom, the Wheelbot provides a challenging platform for nonlinear and data-driven control research.
This work will be presented at IROS 2022 and is part of the article "The Wheelbot: A jumping reaction wheel unicycle", published in the robotics and automation letters (RA-L): ieeexplore.ieee.org/document/...

    The reaction wheel (that's the upper wheel) can tilt the robot by a certain angle. If you want to keep the robot at this angle, the reaction wheel needs to accelerate such that the wheel would eventually reach its rate limit and the robot would topple. However, if the rolling wheel (that's the wheel touching the ground) starts to move the robot 'forward' , a tilted unicycle would start driving on a curve. At a given forward speed, you can find a tilt angle such that the reaction wheel does not need to accelerate to prevent toppling. You can observe a similar maneuver when watching a motorcycle driving through a curve. Here, the motorcyclist adjusts the tilt angle of the motorcycle depending on how fast she's driving through a curve. On the Wheelbot's project page you find a couple of simulation videos in which the Wheelbot drives small turns. We are currently working on this topic.

    @@a.renegeist2800 What about if you had two reaction wheels mounted at an angle above on each side of the driving wheel? Wouldn’t you be able to accelerate them in different direction to instigate a turn easier? And also to turn around its axis standing still.

    @@snabbgas1116 Absolutely! :) If you add a third wheel that is orthogonal to the other two wheels, then you can directly control all three rotational degrees of freedom. Yet, that the robot's "turning dynamics" can not directly be controlled actually becomes a feature if you want to study the "controllability" of under-actuated nonlinear systems or are looking for a simple yet quite challenging system to test your data-driven control algorithms on. In other words, we don't use a third wheel not because it is easy (from a mechanical design point of view) but because it is hard (from a control point of view).
