/*! @class dynamicgraph::sot::FeaturePosture feature-posture.hh |
| 39 |
|
|
* Feature that observes the posture of the robot, ie whose Jacobian is the |
| 40 |
|
|
* identity, or slices of the identity. This feature can be exactly |
| 41 |
|
|
* obtained with a generic posture, given the identity matrix as the input |
| 42 |
|
|
* Jacobian, the identity matrix. It is even prefereable, as the reference |
| 43 |
|
|
* value is then given by a signal, which can be reevalutated at each |
| 44 |
|
|
* iteration, for example to track a reference trajectory in the |
| 45 |
|
|
* configuration space. See for example the toFlag python function in the |
| 46 |
|
|
* sot-dyninv module to nicely selec the posture DOF. |
