Distributed vs. Centralized Particle Swarm Optimization for Learning Flocking Behaviors

Alcherio Martinoli, Inaki Navarro Oiza, Ezequiel Leonardo Di Mario

In this paper we address the automatic synthesis of controllers for the coordinated movement of multiple mobile robots. We use a noise-resistant version of Particle Swarm Optimization to learn in simulation a set of 50 weights of a plastic artificial neura ...

Detection of Slippery Terrain with a Heterogeneous Team of Legged Robots

Roland Siegwart

Legged robots come in a range of sizes and capabilities. By combining these robots into heterogeneous teams, joint locomotion and perception tasks can be achieved by utilizing the diversified features of each robot. In this work we present a framework for ...

Concurrent Optimization of Mechanical Design and Locomotion Control of a Legged Robot

Roland Siegwart

This paper introduces a method to simultaneously optimize design and control parameters for legged robots to improve the performance of locomotion based tasks. The morphology of a quadrupedal robot was optimized for a trotting and bounding gait to achieve ...

Soft Pneumatic Actuator Skin with Embedded Sensors

Jamie Paik, Yun Seong Song, Chansu Suh

Soft Pneumatic Actuator skin (SPA-skin) is a novel concept of ultra-thin (< 1 mm) sensor embedded actuators with distributed actuation points that could cover soft bodies. This highly customizable and flexible SPA-skin is ideal for providing proprioceptive ...

Small, fast and tough: an overview of our silicone-based actuators

Herbert Shea, Samuel Rosset

At the Microsystems for Space Technologies Laboratory, EPFL, we design and manufacture miniaturised silicone-based dielectric elastomer actuators (DEAs). We love silicone, because even though the achievable strain is generally smaller than what you can get ...

2014

Despite great efforts in designing legged robots, we are still far from the adaptivity, efficiency and robustness with which animals can move. Observations from successful biomimetic designs highlight the significant role of clever morphological design in ...

Towards Dynamic Trot Gait Locomotion—Design, Control and Experiments with Cheetah-cub, a Compliant Quadruped Robot

Auke Ijspeert, Massimo Vespignani, Mostafa Ajallooeian, Alexandre Tuleu

We present robot design and results from locomotion experiments with a novel, compliant quadruped robot: Cheetah-cub. The robot's leg configuration is based on a spring-loaded, panthograph-mechanism with multiple segments. A dedicated open-loop, joint-spac ...

Reflexive stability control framework for humanoid robots

Tadej Petric

In this paper we propose a general control framework for ensuring stability of humanoid robots, determined through a normalized zero-moment-point (ZMP). The proposed method is based on the modified prioritized kinematic control, which allows smooth and con ...

2013

This paper introduces a novel batch optimization based calibration framework for legged robots. Given a nondegenerate calibration dataset and considering the stochastic models of the sensors, the task is formulated as a maximum likelihood problem. In order ...

Piecewise linear spine for speed-energy efficiency trade-off in quadruped robots

Auke Ijspeert, Mahdi Khoramshahi

We compare the effects of linear and piecewise linear compliant spines on locomotion performance of quadruped robots in terms of energy efficiency and locomotion speed through a set of simulations and experiments. We first present a simple locomotion syste ...
