Legged robotic systems

Published on in Success Stories

Legged robots are a great promise for future machines to achieve unperceived locomotion capabilities in all kinds of challenging terrain. Inspired by the mechanical principles of human and animal locomotion, a group of researchers at ETH Zurich started creating a new generation of legged robotic systems and the underlying locomotion control technology for running and climbing over rough grounds (figure 1). (In contrast to traditional machines, they are built upon selected compliant elements resulting in precise torque controllability, mechanical energy recuperation, and high impact robustness which makes these robots very well suited for all kinds of real world applications.)

Supported by CTI (Swiss Commission for Technology and Innovation), the developed control and state estimation strategies are today being transferred to walking excavators of Menzi Muck (figure 2). This enables an optimal contact force distribution similar to the robotic dogs, which significantly improves safety and usability of these highly versatile large scale machines.

  1. Cooperation for Robird wins important award - The Future of High Tech

    […] Professor of Advanced Robotics Stefano Stramigioli of the University of Twente and Nico Nijenhuis of Clear Flight Solutions jointly accepted the award in the company of Europe’s leading robotics science, business, and government figures. The TechTransfer award is given to successful forms of cooperation between knowledge institutes and companies, especially start-ups and spin-offs. The Twente team beat off competition from the renowned ETH Zurich team and their walking excavator. […]
