SUMMARY In the natural world, animals must routinely negotiate varied and unpredictable terrain. Yet, we know little about the locomotor strategies used by animals to accomplish this while maintaining dynamic stability. In this paper, we perturb the running of guinea fowl with an unexpected drop in substrate height (ΔH). The drop is camouflaged to remove any visual cue about the upcoming change in terrain that would allow an anticipatory response. To maintain stability upon a sudden drop in… 
Running over rough terrain reveals limb control for intrinsic stability
TLDR
How simple mechanical models extend to unsteady conditions is highlighted, providing fundamental insights into neuromuscular control of movement and the design of dynamically stable legged robots and prosthetic devices.
Birds achieve high robustness in uneven terrain through active control of landing conditions
TLDR
Pheasants appear to achieve robustly stable locomotion through a combination of path planning using visual feedback and active adjustment of leg swing dynamics to control landing conditions, which is suggested to be an active strategy to minimise fluctuations in peak force and leg posture in uneven terrain.
How to run on rough terrains
TLDR
By analyzing the propagation of perturbations, a single dimensionless parameter is derived that governs stability and guides the design and control of both biological and robotic runners.
Compliant legs enable lizards to maintain high running speeds on complex terrains
TLDR
Fast-running Acanthodactylus boskianus lizards can run at high-speed on complex terrains, relying on leg movements that adjust to substrate variations, while enhancing the stability of the head and centre of mass.

TLDR
A review of recent work using terrain perturbations to reveal neuromechanical control strategies used by ground birds to achieve robust, stable, and agile running highlights the crucial role of swing-leg trajectory control for regulating foot contact timing and leg loading in uneven terrain.
Dynamics and stability of running on rough terrains
TLDR
A single dimensionless parameter is derived that governs stability of running on rough terrain and provides guidelines for the design and control of both biological and robotic runners.
Humans falling in holes: adaptations in lower-limb joint mechanics in response to a rapid change in substrate height during human hopping
TLDR
This study determined how the joints of the lower-limb respond to recover from a rapid, unexpected drop in substrate height during human hopping and suggests that humans successfully recover from falling in a hole by increasing the energy absorbed predominantly in distal lower- Limb joints.
Challenging human locomotion: stability and modular organisation in unsteady conditions
TLDR
The hypothesis that humans adjust their motor control strategies’ timing to deal with unsteady locomotion is confirmed and a reduced stability during uneven-surface locomotion and a reorganisation of the modular control is hypothesized.
Running on uneven ground: leg adjustment to vertical steps and self-stability
TLDR
This work found that runners adjust their leg stiffness to the height of a vertical step, and described the identified leg forces and leg compressions with a simple spring–mass simulation for a given body mass, leg stiffness, angle of attack and initial conditions.

Dynamic stabilization of rapid hexapedal locomotion.
TLDR
The rapid onset of recovery from lateral perturbations supports the possibility that, during fast locomotion, intrinsic properties of the musculoskeletal system augment neural stabilization by reflexes.
Running in the real world: adjusting leg stiffness for different surfaces
TLDR
It is found that human runners adjust their leg stiffness to accommodate changes in surface stiffness, allowing them to maintain similar running mechanics on different surfaces, and suggests that incorporating an adjustable leg stiffness in the design of hopping and running robots is important if they are to match the agility and speed of animals on varied terrain.

TLDR
The results of this study indicate that swing-leg retraction significantly improves the stability of spring-mass running, suggesting thatswing-phase limb dynamics may play an important role in the stabilization of running animals.

Groucho running.
TLDR
Results show that running with the knees bent reduces the effective vertical stiffness and diminishes the transmission of mechanical shock from the foot to the skull but requires an increase of as much as 50% in the rate of O2 consumption.

TLDR
This study investigated human hopping on damped surfaces that dissipated up to 72% of the hopper's mechanical energy and found that the combination appeared to behave like a constant stiffness spring on all damping surfaces.

Experiments with a physical 3D one-legged hopping machine showed that this control scheme, while simple to implement, is powerful enough to permit hopping in place, running at a desired rate, and travel along a simple path.
Mechanical work in terrestrial locomotion: two basic mechanisms for minimizing energy expenditure.
TLDR
During running, trotting, hopping, and galloping, the power per unit weight required to maintain the forward speed of the center of mass is almost the same in all the species studied and the sum of these two powers is almost a linear function of speed.
