Towards a Passive Adaptive Planar Foot with Ground Orientation and Contact Force Sensing for Legged Robots

Laura Isabel Paez Coy, Marco Hutter, Klajd Lika

Adapting to the ground enables stable footholds in legged locomotion by exploiting the structure of the terrain. On that account, we present a passive adaptive planar foot with three rotational degrees of freedom that is lightweight and thus suited for hig ...

Frequency-Aware Model Predictive Control

Marco Hutter, Farbod Farshidian

Transferring solutions found by trajectory optimization to robotic hardware remains a challenging task. When the optimization fully exploits the provided model to perform dynamic tasks, the presence of unmodeled dynamics renders the motion infeasible on th ...

Locomotion Planning through a Hybrid Bayesian Trajectory Optimization

Marco Hutter, Farbod Farshidian

Locomotion planning for legged systems requires reasoning about suitable contact schedules. The contact sequence and timings constitute a hybrid dynamical system and prescribe a subset of achievable motions. State-of-the-art approaches cast motion planning ...

The current state and future outlook of rescue robotics

Dario Floreano, Auke Ijspeert, Roland Siegwart, Stefano Mintchev, Kamilo Andres Melo Becerra, Davide Scaramuzza, Tomislav Horvat, Marco Hutter

Robotic technologies, whether they are remotely operated vehicles, autonomous agents, assistive devices, or novel control interfaces, offer many promising capabilities for deployment in real‐world environments. Postdisaster scenarios are a particularly rel ...

Keep Rollin’—Whole-Body Motion Control and Planning for Wheeled Quadrupedal Robots

Marco Hutter

We show dynamic locomotion strategies for wheeled quadrupedal robots that combine the advantages of both walking and driving. The developed optimization framework tightly integrates the additional degrees of freedom introduced by the wheels. Our approach r ...

Learning agile and dynamic motor skills for legged robots

Marco Hutter

Legged robots pose one of the greatest challenges in robotics. Dynamic and agile maneuvers of animals cannot be imitated by existing methods that are crafted by humans. A compelling alternative is reinforcement learning, which requires minimal craftsmanshi ...

The dynamics of legged systems are characterized by under-actuation, instability, and contact state switching. We present a trajectory optimization method for generating physically consistent motions under these conditions. By integrating a custom solver f ...
