I'm going to take an educated guess that using mo-cap data wouldn't work, simply because the weight distributions of people and the BD robots are completely difference.
If I had to take a guess, I'd say that they were given a timeline of locations of extremities and chest/trunk and the magic sauce took care of how to distribute the weight to make it work, like a footprint chart
- dagmx 6y agoYou can run a solve on animation to accommodate physical artifacts like vibrations and other weights. Disney have a paper on this for their robotics: https://youtu.be/Z1jgaEO9aRs https://youtu.be/Z1jgaEO9aRs Though of course Disney have very different constraints, however it does illustrate that you can map from mocap to robotics motions by running solves and reversing out the artifacts. Those can be encoded into timed poses and combine that with their real time compensation to achieve this motion
- kolinko 6y agoIt won’t work for standing robots because those need to adjust for dynamic variables or they will fall down with the first tiny gust of wind (or floor micro-shake) Disney animatronics don’t have this problem because they are attached to the ground.
- dagmx 6y agoMy last paragraph mentions that aspect already. You can run some amount of the solve before hand based on what you know, and combine that with the real-time physics adjustment that these robots already do to accommodate for any differences at "runtime".
