Collaborative Task and Path Planning for Heterogeneous Robotic Teams using Multi-Agent PPO
Matthias Rubio, Julia Richter, Hendrik Kolvenbach +1
Efficient robotic extraterrestrial exploration requires robots with diverse capabilities, ranging from scientific measurement tools to advanced locomotion. A robotic team enables t…
MOSAIC: Modular Scalable Autonomy for Intelligent Coordination of Heterogeneous Robotic Teams
David Oberacker, Julia Richter, Philip Arm +10
Mobile robots have become indispensable for exploring hostile environments, such as in space or disaster relief scenarios, but often remain limited to teleoperation by a human oper…
A Practical Framework of Key Performance Indicators for Multi-Robot Lunar and Planetary Field Tests
Julia Richter, David Oberacker, Gabriela Ligeza +10
Robotic prospecting for critical resources on the Moon, such as ilmenite, rare earth elements, and water ice, requires robust exploration methods given the diverse terrain and hars…
Efficient Learning-Based Control of a Legged Robot in Lunar Gravity
Philip Arm, Oliver Fischer, Joseph Church +3
Legged robots are promising candidates for exploring challenging areas on low-gravity bodies such as the Moon, Mars, or asteroids, thanks to their advanced mobility on unstructured…
An Efficient Multi-Robot Arm Coordination Strategy for Pick-and-Place Tasks using Reinforcement Learning
Tizian Jermann, Hendrik Kolvenbach, Fidel Esquivel Estay +2
We introduce a novel strategy for multi-robot sorting of waste objects using Reinforcement Learning. Our focus lies on finding optimal picking strategies that facilitate an effecti…
Multi-Objective Global Path Planning for Lunar Exploration With a Quadruped Robot
Julia Richter, Hendrik Kolvenbach, Giorgio Valsecchi +1
In unstructured environments the best path is not always the shortest, but needs to consider various objectives like energy efficiency, risk of failure or scientific outcome. This…
SpaceHopper: A Small-Scale Legged Robot for Exploring Low-Gravity Celestial Bodies
Alexander Spiridonov, Fabio Buehler, Moriz Berclaz +12
We present SpaceHopper, a three-legged, small-scale robot designed for future mobile exploration of asteroids and moons. The robot weighs 5.2kg and has a body size of 245mm while u…
Pedipulate: Enabling Manipulation Skills using a Quadruped Robot's Leg
Philip Arm, Mayank Mittal, Hendrik Kolvenbach +1
Legged robots have the potential to become vital in maintenance, home support, and exploration scenarios. In order to interact with and manipulate their environments, most legged r…
Scientific Exploration of Challenging Planetary Analog Environments with a Team of Legged Robots
Philip Arm, Gabriel Waibel, Jan Preisig +8
The interest in exploring planetary bodies for scientific investigation and in-situ resource utilization is ever-rising. Yet, many sites of interest are inaccessible to state-of-th…
Cat-like Jumping and Landing of Legged Robots in Low-gravity Using Deep Reinforcement Learning
Nikita Rudin, Hendrik Kolvenbach, Vassilios Tsounis +1
In this article, we show that learned policies can be applied to solve legged locomotion control tasks with extensive flight phases, such as those encountered in space exploration.…
Traversing Steep and Granular Martian Analog Slopes With a Dynamic Quadrupedal Robot
Hendrik Kolvenbach, Philip Arm, Elias Hampp +5
Celestial bodies such as the Moon and Mars are mainly covered by loose, granular soil, a notoriously challenging terrain to traverse with (wheeled) robotic systems. Here, we presen…
Cable-Driven Actuation for Highly Dynamic Robotic Systems
Jemin Hwangbo, Vassilios Tsounis, Hendrik Kolvenbach +1
This paper presents design and experimental evaluations of an articulated robotic limb called Capler-Leg. The key element of Capler-Leg is its single-stage cable-pulley transmissio…
