alter_motion(pos)

Features

This function applies altering amount of motion trajectory when the alter function is activated. The meaning of the input values is defined in the description of enable_alter_motion().

  • alter_motion() can be executed only in user thread.


  • alter_motion() can be executed only in user thread.

  • Alter motion can be adjusted through setting value limit_dPOS or limit_dPOS_per in enable_alter_motion function.

  • Orientation of Input pose follows fixed XYZ notation.
