1) They actually open sourced the vision pipeline code a few months ago. The visiond binary has been replaced by source code.
2) Yeah. The proper way to do these things is with a real RTOS, but at the same time 20hz is pretty slow anyways.
- a-dub 7y agoI should also mention that the RT approach isn't the holy grail either for time sensitive robotic control systems. Read up on the Pathfinder/vxWorks priority inversion bug if you'd like to see how hard deadlines can sometimes cause more problems than they solve...
- MuffinFlavored 7y agoWhat’s the answer then?
- TickleSteve 7y agopriority-inversion is well-known and easily coped with. Hard real-time, deterministic code is simply a prerequisite for safety in these types of systems, you have to be able to reason about how your system will behave in worst-case situations.
- bri3d 7y agoThe model, training tooling, and data appear to still be closed, no? So it’s still a black box, just now the “load the model binary and run it” part is open source.
