The KogMo-RTDB interfaces can be regarded as part of an outer framework for interprocess communication. The actual inner framework used within a cognitive module heavily depends on the engineering discipline it comes from: for the control level, this might be a robotics or control framework, at an artificial intelligence level an interference machine might be the choice.
- The license has been changed from LGPL to Apache License 2.0 (2011-12-31)
- The code has been moved to GitHub (2011-12-19)
- Real-time Database as central interface for interprocess communication (event trigger available)
- Data exchange between both real-time and non-real-time modules
- Data consistency guaranteed by non-blocking read/write protocol
- History for temporal decoupling of slower modules with longer cycle times
- Comprehensive data logging using an interference-free method
- Hard real-time capable with specified hard- and software platform
- Reference platform for hard real-time:
GNU/Linux (CentOS 4) with Kernel 220.127.116.11 and Xenomai 2.4.4
- Full functionality with soft real-time:
C compiler and a POSIX compatible system (uses pthreads, mutexes, condvars, message queues, shared memory)
- Minimal requirements (no real-time):
shared memory (e.g. tmpfs on /dev/shm/)
emulates mutexes with polling and atomic instructions on x86, arm and mips
- Successfully running on embedded systems:
- Cognitive Automobiles (Transregional Collaborative Research Center 28 funded by Deutsche Forschungsgemeinschaft)
- The autonomous robot car AnnieWAY(photo) at the DARPA Urban Challenge 2007
- Cognitive Factory and Cognitive Household (Cognition for Technical Systems)
