They enable safe training and testing of robots. However, even the most sophisticated ones fail to capture the “noise” of the real world because of idealised physics and unnatural visuals. Simulated environments are essential for robotics. They enable safe training and testing of robots. However, even the most sophisticated ones fail to capture the “noise” of the real world because of idealised physics and unnatural visuals. Interactive World Models are different. They are visually more realistic, and can model more complex phenomena such as folding materials or squeezing towels. By embedding digital replicas into these dynamic environments, robots can execute commands through direct interaction. Here is the challenge though. True interactivity requires a world model to accurately respond to low-level commands (e.g., moving left or right).
