The framework embeds a kernel which is a fully parametric closed-loop gait generator based on analytical control. ...
On top of that, a neural network with symmetric partial data augmentation learns to automatically adjust the parameters for the gait kernel and to generate compensatory actions for all joints as the residual ...
CONCLUSION In this paper, we proposed a locomotion framework based on a tight coupling between analytical control and deep reinforcement learning to combine the potential of both approaches. ...

In this paper, a hybrid motion controller including both a posture controller based on visual feedback and an end-effector motion controller based on encoder signal is proposed. ...
Second, a novel controller that is based on the above analysis is proposed, and it is shown that this controller is equivalent to a velocity based motion-copying system, which we proposed in the past. ...

Hybrid systems, such as bipedal walkers, are challenging to control because of discontinuities in their nonlinear dynamics. ...
The algorithm is used with data-driven dynamics identification to enable model predictive control based entirely on data. ...
Specifically, the learned dynamics could be used to predict the system's forward evolution over time and to then calculate a stabilizing control signal using model predictive control to e.g., assist a ...
