Whole-Body Nonlinear Model Predictive Control Through Contacts for Quadrupeds
Michael Neunert, Markus Stäuble, Markus Giftthaler +5
In this work we present a whole-body Nonlinear Model Predictive Control approach for Rigid Body Systems subject to contacts. We use a full dynamic system model which also includes…
Real-Time Motion Planning of Legged Robots: A Model Predictive Control Approach
Farbod Farshidian, Edo Jelavić, Asutosh Satapathy +2
We introduce a real-time, constrained, nonlinear Model Predictive Control for the motion planning of legged robots. The proposed approach uses a constrained optimal control algorit…
Automatic Differentiation of Rigid Body Dynamics for Optimal Control and Estimation
Markus Giftthaler, Michael Neunert, Markus Stäuble +3
Many algorithms for control, optimization and estimation in robotics depend on derivatives of the underlying system dynamics, e.g. to compute linearizations, sensitivities or gradi…
Fast Trajectory Optimization for Legged Robots using Vertex-based ZMP Constraints
Alexander W Winkler, Farbod Farshidian, Diego Pardo +2
This paper combines the fast Zero-Moment-Point (ZMP) approaches that work well in practice with the broader range of capabilities of a Trajectory Optimization formulation, by optim…
Robust Whole-Body Motion Control of Legged Robots
Farbod Farshidian, Edo Jelavić, Alexander W. Winkler +1
We introduce a robust control architecture for the whole-body motion control of torque controlled robots with arms and legs. The method is based on the robust control of contact fo…
Mobile Robotic Fabrication at 1:1 scale: the In situ Fabricator
Markus Giftthaler, Timothy Sandy, Kathrin Dörfler +6
This paper presents the concept of an In situ Fabricator, a mobile robot intended for on-site manufacturing, assembly and digital fabrication. We present an overview of a prototype…
Efficient Kinematic Planning for Mobile Manipulators with Non-holonomic Constraints Using Optimal Control
Markus Giftthaler, Farbod Farshidian, Timothy Sandy +2
This work addresses the problem of kinematic trajectory planning for mobile manipulators with non-holonomic constraints, and holonomic operational-space tracking constraints. We ob…
