Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Investigation into the hovering flight dynamics and control of a flapping wing micro air vehicle [PDF]

, 2003
The hovering flight of a micro air vehicle was investigated. Various flight control concepts, inspired by observation of insect and bird flight, were investigated in some detail. The concepts make use of flap frequency or phase between the flap and pitch

A Free-Flight Simulation of Insect Flapping Flight

Journal of Aero Aqua Bio-mechanisms, 2010
In insect flapping flight, non-equilibrium flight conditions such as takeoffs and uncoordinated turn are difficult to investigate with experiments or quasi-steady analysis. Here we develop a simplified rigid body dynamics solver with 6 degrees of freedom (DOF), by utilizing unit quaternions.

A Neural Adaptive Controller in Flapping Flight

Journal of Robotics and Mechatronics, 2012
In this paper, we propose a neural adaptive controller for attitude control in a flapping-wing insect model. The model is nonlinear and subjected to periodic force/torque generated by nominal wing kinematics. Two sets of model parameters are obtained from the fruit flyDrosophila melanogasterand the honey beeApis mellifera.

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.
