-The example shows velocity-based WBC on a hybrid dual-arm robot (fixed base). The outputs are the actuator velocities that comply with the given task space velocities. In contrast to the previous example, the solution respects the internal closed-loop mechanisms of the RH5v2 robot and is mapped directly to actuation space (see the respective [paper](https://arc-opt.github.io/Documentation/publications/icra_2022/index.html) for more details.
