The iTaSC Software
The software implements the iTaSC-Skill framework in Orocos, which is integrated in ROS by the Orocos-ROS-integration . The Real-Time Toolkit (RTT) of the Orocos project enables the control of robots on a hard-realtime capable operating system, e.g. Xenomai-Linux or RTAI-Linux. The rFSM subproject of Orocos allows scripted Finite State Machines, hence Skills, to be executed in hard realtime. The figure below shows the software architecture, mentioning the formulas for the resolved velocity case without prioritization for clarification. The key advantages of the software design include:
- the modular design, allowing users to implement their own solver, scene graph, motion generators ...,
- the modular task specification that allows users to reuse tasks, and enables a future task-web application to down- or upload tasks,
- the flexible user interface, allowing users to change the weights and priorities of different constraints, and to add or remove constraints.
Furthermore, the Bayesian Filtering Library (BFL) and Kinematics and Dynamics Library (KDL) of the Orocos project are used to retrieve stable estimates out of sensor data, and to specify robot and virtual kinematic chains respectively.

RoadmapWe are interested in (contributions to):
- Include other types of constraints, eg. inequality constraints
- Expand the capabilities to include uncertainty constraints (and make a nice example/tutorial)
- Include resolved acceleration control
- Make more tutorials and examples (eg. including MTTD)
