What they are saying in the article is that they are optimizing the movements using a physical model so that they don't need passive damping.. but isn't that exactly what active damping is?
- lawlessone 7y agoit's preparing the movements in advance via simulation, is it still active damping if it has done that?
- Retric 7y agoThey actually mention active damping in the video so yes. It’s less resilient as ware will make the robots inconsistent over time, but the tradeoff for a less costly robot with fewer sensors may be worth it.
- faceplanted 7y agoI don't think so, no. It would need to be reactive to active damping, and as the article says, there aren't any onboard sensors, so if you push them they'll wobble like crazy.
- rtkwe 7y agoIt's a tricky distinction because the program is changed to dampen the vibrations but it's all baked into the program at start it seems. I'd say it's not active because it doesn't dynamically monitor and change the program. In theory you could perturb these animatronics in such a way that their damping motions actually increase the vibrations.
- htgb 7y agoI think of the term optimal control [1] given that problem description. Maybe there's some overlap in the definitions? [1] https://en.wikipedia.org/wiki/Optimal_control https://en.wikipedia.org/wiki/Optimal_control
