DOI: 10.1007/s12567-018-0212-x
Abstract: Latest large spacecraft and/or agility requirements have led to configurations of five or more reaction wheels. To avoid (1) handling a significant amount of pre-stored parameters on board and (2) intervening by ground (classical approach)… read more here.

DOI: 10.1016/j.ifacol.2019.11.813
Abstract: Abstract This paper proposes a novel method for easily generating a strict stealth walking gait of an underactuated rimless wheel (URW) by temporally controlling the stance-leg angle using an additional control torque. First, we introduce… read more here.

DOI: 10.1080/00207179.2018.1562224
Abstract: ABSTRACT A robust controller is designed using an LMI-based technique. In this approach, the controller synthesis is similar to an LQR, but with the possibility of considering parametric uncertainties. The designed controller is applied to… read more here.

The Wheelbot: A Jumping Reaction Wheel Unicycle
Sign Up to like & getrecommendations! Published in 2022 at "IEEE Robotics and Automation Letters"
DOI: 10.48550/arxiv.2207.06988
Abstract: 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… read more here.
