Proceedings ArticleDOI
Capture Point: A Step toward Humanoid Push Recovery
TL;DR: The well-known linear inverted pendulum model is extended to include a flywheel body and it is shown how to compute exact solutions of the capture region for this model, the region on the ground where a humanoid must step to in order to come to a complete stop.
Journal ArticleDOI
Capturability-based analysis and control of legged locomotion, Part 2: Application to M2V2, a lower-body humanoid
Jerry Pratt,Twan Koolen,Tomas De Boer,John R. Rebula,Sebastien Cotton,John Carff,Matthew Johnson,Peter Neuhaus +7 more
TL;DR: An algorithm that uses the ability of a legged system to come to a stop without falling by taking N or fewer steps and novel instantaneous capture point control strategies as approximations to control a humanoid robot is described.
Journal ArticleDOI
Team IHMC's Lessons Learned from the DARPA Robotics Challenge Trials
Matthew Johnson,Brandon Shrewsbury,Sylvain Bertrand,Tingfan Wu,Daniel Duran,Marshall Floyd,Peter Abeles,Douglas Stephen,Nathan Mertins,Alex Lesman,John Carff,William Rifenburgh,Pushyami Kaveti,Wessel Straatman,Jesper Smith,Maarten Griffioen,Brooke Layton,Tomas De Boer,Twan Koolen,Peter Neuhaus,Jerry Pratt +20 more
TL;DR: The challenges the IHMC team faced in transitioning from simulation to hardware and the lessons learned both during the DRC Trials and in the months of preparation leading up to it are discussed.

Thomas,Sylvain Bertrand,John Carff,Nathan Mertins,Douglas Stephen,Peter Abeles,Johannes Englsberger,Stephen McCrory,Jeff van Egmond,Maarten Griffioen,Marshall Floyd,Samantha Kobus,Nolan Manor,Sami Alsheikh,Daniel Duran,Larry Bunch,Eric Morphis,Luca Colasanto,Khai-Long Ho Hoang,Brooke Layton,Peter Neuhaus,Matthew D. Johnson,Jerry Pratt +24 more

Team IHMC's Lessons Learned from the DARPA Robotics Challenge: Finding Data in the Rubble
Matthew Johnson,Brandon Shrewsbury,Sylvain Bertrand,Duncan Calvert,Tingfan Wu,Daniel Duran,Douglas Stephen,Nathan Mertins,John Carff,William Rifenburgh,Jesper Smith,Chris Schmidt-Wetekam,Davide Faconti,Alex Graber-Tilton,Nicolas Eyssette,Tobias Meier,Igor Kalkov,Travis Craig,Nick Payton,Stephen McCrory,Georg Wiedebach,Brooke Layton,Peter Neuhaus,Jerry Pratt +23 more
TL;DR: A retrospective analysis of Team IHMC's experience throughout the DARPA Robotics Challenge, where they took first or second place overall in each of the three phases, and some of the significant lessons learned that contributed to their success in the DRC are discussed.
