CORC is a free and open source robotic development software stack, written in C++.
The project was initiated at the University of Melbourne in partnership with Fourier Intelligence, however has welcomed (and continues to welcome) collaborators from all institutions. The project was initially developed to run on an ExoMotus X2 Exoskeleton powered by a Beaglebone Black, however, the software is designed to be extensible to any embedded Linux and CANopen enabled Robotic platform. The repository currently also includes code which has been run on the ArmMotus M1, M2 and M3 (EMU) rehabilitation devices, and using desktop or laptop Ubuntu installations.
- An extensible framework to represent multibody rigid robotic systems.
- An event driven state machine to develop custom applications (see here).
- An implementation of CANopen Socket to provide an interface between CAN enabled embedded Linux system and CANopen-based motor drivers/sensors.
- Documentation (this page and associated ones and code Doxygen).
- Functional application examples.
The code is structured into 3 levels:
- The CANopen Communications Level: Provides the CAN-level communications, providing the mechanisms for the sending and receiving of PDO and SDO messages
- The Robot Level: Defines the components of the Robot to be controlled, including the joints, associated drives, and input devices
- The Application Layer: Defines the high level logic for the device, based on the implementation of a State Machine.
Whilst the code can be modified at any level, this structure is designed to provide a degree of modularity. The CANopen Communications level should not need to be changed. The Robot level should only change with respect if the robot to be controlled changes. This is loosely enforced by the source code folder structure - the files which should not need modification are placed in the src/core folder, and the remainder are placed in the src/apps and src/hardware folders. Note that in addition to the CANopen Communication code, the src/core folder also includes base classes which are derived from in the src/apps and src/hardware folders.

See this detailed explanation for instructions to customise an application or derive your own.
CORC relies on spdlog for both general logging (terminal and in file) and for data logging. See here for more info on using the logging system.
See here for instructions on how to build and run a CORC app with ROS support.
See here for instructions on using libFLNL for communication.
See this page for notes on tested USB-CAN adapters.
To generate the Doxygen documentation of the code you can simply run doxygen Doxyfile in the root folder. This will generate an HTML documentation in the doc/html folder.
