Inverted landing is a challenging feat to perform in aerial robots, especially without external positioning. However, it is routinely performed by biological fliers such as bees, flies, and bats. Our previous observations of landing behaviors in flies suggest an open-loop causal relationship between their putative visual cues and the kinematics of the aerial maneuvers executed. For example, the degree of rotational maneuver (the amount of body inversion prior to touchdown) and the amount of leg…

TLDR
Simulation results show that the aerial robot is able to achieve robust inverted landing, and it tends to exploit its maximal maneuverability.

The visual control of landing and obstacle avoidance in the fruit fly Drosophila melanogaster

TLDR
Using a real-time 3D tracking system in conjunction with high speed digital imaging, the results suggest that landing is composed of three distinct behavioral modules, which provide insight into the organization of sensorimotor modules that underlie the landing and search behaviors of insects.

Falling with Style: Bats Perform Complex Aerial Rotations by Adjusting Wing Inertia

TLDR
Bats can, therefore, use their wings as multifunctional organs, capable of sophisticated aerodynamic and inertial dynamics not previously observed in other flying animals, which may also have implications for the control of aerial robotic vehicles.

Aggressive Visual Perching with Quadrotors on Inclined Surfaces

TLDR
This paper focuses on planning and executing dynamically feasible trajectories to navigate and perch to a desired target location with on board sensing and computation and supports certain classes of nonlinear global constraints by leveraging an efficient algorithm that is mathematically verified.

Flies land upside down on a ceiling using rapid visually mediated rotational maneuvers

TLDR
It is reported that successful inverted landing in flies involves a serial sequence of well-coordinated behavioral modules, consisting of an initial upward acceleration followed by rapid body rotation and leg extension, before terminating with a leg-assisted body swing pivoted around legs firmly attached to the ceiling.

Monocular distance estimation from optic flow during active landing maneuvers.

TLDR
This paper uses a nonlinear control theoretic approach to propose a solution to the problem of how does an insect estimate distance solely using optic flow, and takes advantage of visually controlled landing trajectories that have been observed in flies and honeybees.

A universal strategy for visually guided landing

TLDR
A mathematical model is developed that can be used to guide smooth landings on surfaces of any orientation, including horizontal surfaces, and finds that landing honey bees control their speed by holding the rate of expansion of the image constant, which ensures that speed is reduced, gradually and automatically, as the surface is approached.

Trajectory generation and control for precise aggressive maneuvers with quadrotors

TLDR
It is shown that this approach permits the development of trajectories and controllers enabling such aggressive maneuvers as flying through narrow, vertical gaps and perching on inverted surfaces with high precision and repeatability.

The moment before touchdown: landing manoeuvres of the honeybee Apis mellifera

TLDR
The tight correlation between the tilt of the surface, and the orientation of the body and the antennae, indicates that the bee's visual system is capable of inferring the tilt, and pointing the antennase toward it, and that bees use a landing strategy that is flexibly tailored to the varying topography of the terrain.

Nonlinear robust tracking control of a quadrotor UAV on SE(3)

TLDR
This paper provides nonlinear tracking control systems for a quadrotor unmanned aerial vehicle (UAV) that are robust to bounded uncertainties and the size of the ultimate bound can be arbitrarily reduced by control system parameters.
