In the first video, it looks like there are intersection issues (the block being carried by the agent appears to pass through other blocks). The agent hovers above the ground, and manipulates blocks but has no visible manipulators. When the agent drops several levels, I cannot tell if it is accelerating as it falls. So what do they mean exactly when they say this is a "physics-based simulation"?
- alex_petrenko 5y agoThere is a physics engine underneath, but the physics interactions are simplified for accelerated training. I.e. blocks that the agents carry can pass through other blocks, but the agents can't pass through blocks that are already placed. Such simplification allows the high throughput. There is a section in the article that explains the motivation behind this: there are a lot of questions in embodied AI that can be answered with such simplified simulators, i.e. you need something more complex than Atari, but you don't need the full complexity of the real world.
