Towards Attractor Based Dynamic Stepping
In this video we show improvements on phase-space dynamic walking based on using an absolute return frame and the addition of Coriolis/centrifugal effects. The description of the planner can be found on Arxiv Preprint
IHMC NASA JSC X1 Exoskeleton Powered with UT-SEA Ankles
The Human Centered Robotics laboratory at UT Austin has collaborated with IHMC and NASA to integrate the high performance UT-SEA actuator in the X1 Exoskeleton assistive exoskeleton. The high power to weight ratio of the UT-SEA actuator provides a practical…
Full-Body Collision Detection and Reaction with Omnidirectional Mobile Platforms: A Step Towards Safe Human-Robot Interaction
Arxiv Preprint. In the video below, we develop estimation and control methods for quickly reacting to collisions between omnidirectional mobile platforms and their environment. To enable the full-body detection of external forces, we use torque sensors located in the robot’s…
Hume Biped Robot Performing Balance on Split Terrain and Undirected Walking
Arxiv Preprint. The first experiment, shows the Hume biped robot balancing on a high pitch split terrain with and without push disturbances. We implement a Whole-Body Operational Space Controller to compute joint torques consistent with a desired set of operational…
Nick Paine Defends his PhD
Congratulations to Nick Paine for defending and passing his PhD defense. What a wonderful thesis: The UT-SEA, Valkyrie, Darpa Robotics Challenge, …
NASA Valkyrie Mechatronic Development – UT Austin Contributions on Design and Embedded Controls
The Valkyrie humanoid robot was built at NASA Johnson Space Center with leadership from Nic Radford and Rob Ambrose. The Human Centered Robotics Lab at UT Austin provided expertise in the design of rotary series elastic actuators and inspiration for…
The Legend of the Drunken Robot
This research is sponsored by the US Office of Naval Research. Hume uses its series elastic actuated legs to remain balanced while walking. It achieves this capability by observing the center of mass position error relative to a reference path…
First Implementation of Whole-Body Compliant Control with Internal Force Optimization on Hume
This movie shows the first successful implementation of the whole-body compliant controller ( IEEE TRO 2010) on Hume using its series elastic actuators . During the single contact phase, the robot’s hip height and Saggital position, its torso orientation, and…
Snapshots of Dreamer in the Transformers 4: Age of Extinction movie with Nicola Peltz and Mark Wahlberg
We filmed in Elgin, Texas with Director Michael Bay and actors Nicola Peltz and Mark Wahlberg. There is no wonder why the movie became a mega hit 😉
