Actuators are extremely difficult to model accurately.
Actuator Networks is a data driven solution that can provide better simulation of an actuator via supervised learning.
collect joint position errors, velocities, and torque using a controller for more than a million samples with varied amplitude and frequency and manual disturbances for diverse situation.
Proposed two-stage training procedure, which first train a privileged agent and then using the agent as a teacher to train a purely vision-based system, for effective imitation learning. This paradigm is the underlying concept in the legged RL.
Presents a training setup that achieves fast policy generation for real-world robotic tasks by using massive parallelism on a single workstation GPU (showcase of Isaac Gym).
Presented a three stage training and deploy method to perform zero-shot sim-to-real transfer [1].
