Detailed Description

Hybrid position-force control on a contacting end-effector.

The AdmittanceTask is by default a TransformTask, i.e. pure position control of a frame. Admittance coefficients that map force errors to displacements (see [1] and [2]) are initially set to zero.

When the admittance along one axis (Fx, Fy, Fz, Tx, Ty or Tz) is set to a non-zero positive value, this axis switches from position to force control. The goal is then to realize the prescribed target wrench at the control frame (bis repetita placent: wrenches are expressed in the control frame of the task, not in the sensor frame of the corresponding body). The force control law applied is damping control [3].

See the discussion in [4] for a comparison with the ComplianceTask.
