Engineering & simulationLarge Behavior Models (LBMs)20 hours of teleoperation data
Boston Dynamics used teleoperation data and machine learning to train models that allow the Atlas robot to generalize manipulation tasks and react to environmental disturbances in real time.
“we're using teleoperation as a way to demonstrate examples of the behavior that we want the robot to perform, and then we're using, basically machine learning to take those that data and turn it into a model that can perform many of the tasks that we demonstrated.”
Engineering & simulationLarge Behavior Models (LBMs)20 hours of data; cloud computing cluster
The team collected 20 hours of human teleoperation data, annotated it with language, and trained a neural network on a cloud computing cluster to create a policy that controls the robot's closed-loop manipulation.
“So for the spot workshop task, I think we, we probably had on the order of, uh, 20 hours of data. … we take that data. it's annotated now. We run training. This is typically done on a, you know, a cloud, uh, computing cluster, lots of GPUs.”
Engineering & simulationSimulation
The team leveraged simulation to perform many evaluation rollouts, allowing them to generate statistically significant statements about policy performance differences without needing to run every test on physical hardware.
“It's also really useful to leverage simulation as a way to get many, many, um, evaluation rollouts. So our collaborators TRI had a paper that they released a month ago, I think did a great job of this and just leveraging lots and lots of simulation rollouts so they can get statistically significant statements about the difference in performance…”
Engineering & simulationSimulationimproved performance on physical robot
Incorporating simulation data as part of the training mixture with real robot data was found to improve the performance of the policy on the physical robot.
“We've actually found, in our experience, that, um, and other groups have too, that incorporating simulation data as part of the training mixture actually improves performance on the physical robot, which is really exciting.”
