Gait and Trajectory Optimization through Phase-based End-Effector Parameterization

[@yidongmei4679]

Impressive work!! I wonder if there are some videos about real robots on more complex terrains?

[@gondala]

I am curious if this robot also using "virtual" sensors i.e. it is very useful in real world?

Was this trained using simulated imperfections in the aforementioned areas (force tracking and sensor data?) If not I would be interesting to see if it copes better in reality.

I think "trained" is the wrong word here. The gait trajectory generation is posed as a nonlinear programming problem and solved iteratively. A new problem is solved for every plan. The plans are then tracked by a feedback controller to help with disturbances / imperfections.

Thank you for clearing that up for me and explaining the iterative nature. I was thinking more along the neural network path, so I thought it was being "trained". Very interesting

Very impressive. What is the simulator?

[@alexanderwinkler6821]

The first clips are visualization using ros-rviz and wiki.ros.org/xpp, the simulations are done in Gazebo.

Many thanks indeed!
