set_singular_handling_force()

Definition

set_singular_handling_force(mode)

Features

The program is terminated by default through error processing when compliance or force control are used within the singularity area. It is possible to ignore error processing within the singularity area by changing the Mode setting.

  • Error Processing : DR_SINGULARITY_ERROR

  • Ignore Error Processing : DR_SINGULARITY_IGNORE

Caution

Compliance and force control within the singularity area are not recommended. The force estimate in a particular direction can be inaccurate.
