Kamino: GPU-based Simulation of Rigid Multi-Body Physics with Kinematic Loops
Vassilios Tsounis, Guirec Maloisel, Christian Schumacher +6
We present Kamino, a GPU-based physics solver for massively parallel simulations of heterogeneous highly-coupled mechanical systems. Implemented in Python using NVIDIA Warp and int…
On Solving the Dynamics of Constrained Rigid Multi-Body Systems with Kinematic Loops
Vassilios Tsounis, Ruben Grandia, Moritz Bächer
This technical report provides an in-depth evaluation of both established and state-of-the-art methods for simulating constrained rigid multi-body systems with hard-contact dynamic…
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.…
DeepGait: Planning and Control of Quadrupedal Gaits using Deep Reinforcement Learning
Vassilios Tsounis, Mitja Alge, Joonho Lee +2
This paper addresses the problem of legged locomotion in non-flat terrain. As legged robots such as quadrupeds are to be deployed in terrains with geometries which are difficult to…
Learning agile and dynamic motor skills for legged robots
Jemin Hwangbo, Joonho Lee, Alexey Dosovitskiy +4
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 compellin…
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…
