Accurate and precise terrain estimation is a difficult problem for robot locomotion in real-world environments. Thus, it is useful to have systems that do not depend on accurate estimation to the point of fragility. In this paper, we explore the limits of such an approach by investigating the problem of traversing stair-like terrain without any external perception or terrain models on a bipedal robot. For such blind bipedal platforms, the problem appears difficult (even for humans) due to the…

Learning Bipedal Walking On Planned Footsteps For Humanoid Robots

TLDR
This paper shows that simply feeding the upcoming 2 steps to the policy iscient to achieve omnidirectional walking, turning in place, standing, and climbing stairs, and employs curriculum learning on the complexity of terrains, and circumvents the need for reference motions or pre-trained weights.

TLDR
An attention-based recurrent encoder is leverage that integrates proprioceptive and exteroceptive input and learns to seamlessly combine the different perception modalities without resorting to heuristics to create a legged locomotion controller with high robustness and speed.

TLDR
This paper develops an RL formulation for training dynamic gait controllers that can respond to specified touchdown locations and uses supervised learning to induce a transition model for accurately predicting the next touchdown locations that the controller can achieve given the robot's proprioceptive observations.

Learning Coordinated Terrain-Adaptive Locomotion by Imitating a Centroidal Dynamics Planner

TLDR
This work shows that terrain adaptive controllers can be obtained by training policies to imitate trajectories that have been planned over procedural terrains by a non-linear solver and shows that the learned policies transfer to unseen terrains and can be fine-tuned to dynamically traverse challenging terrains that require precise foot placements and are very hard to solve with standard RL.

TLDR
This paper proposes A-RMA (Adapting RMA), which additionally adapts the base policy for the imperfect extrinsics estimator by tuning it using model-free RL.

Legged Robots that Keep on Learning: Fine-Tuning Locomotion Policies in the Real World

TLDR
It is demonstrated that a modest amount of real-world training can substantially improve performance during deployment, and this enables a real A1 quadrupedal robot to autonomously fine-tune multiple locomotion skills in a range of environments, including an outdoor lawn and a variety of indoor terrains.

Linear Policies are Sufficient to Realize Robust Bipedal Walking on Challenging Terrains

TLDR
This work proposes a new control pipeline, wherein the high-level trajectory modulator shapes the end-foot ellipsoidal trajectories, and the low-level gait controller regulates the torso and ankle orientation, and uses a linear PD control law.

Towards Real Robot Learning in the Wild: A Case Study in Bipedal Locomotion

TLDR
This paper demonstrates how a small bipedal robot can autonomously learn to walk with minimal human intervention and with minimal instrumentation of the environment, using data-efficient off-policy deep reinforcement learning to learn towalk end-to-end, directly on hardware.
