MakerMods robot arm in MuJoCo (X)
A video demo drives a MakerMods robot arm in MuJoCo using Jev: the model receives the scene as JSON state and picks the next bounded action, such as hover, descend, grasp, lift, or place, as a typed choice with a confidence score, completing a task in 9 decisions at about 150 milliseconds each.

DiscussionJev Ultrafast: A browser agent with a dynamic action space (HN)
