    • moveTo

      public Justification moveTo(String group_name, javax.vecmath.Point3d point_l, javax.vecmath.Quat4d orientation_l, javax.vecmath.Point3d point_r, javax.vecmath.Quat4d orientation_r)
      Description copied from interface: ArmInterface
      Move the groupName to specified poses(s). If group name only contains a single arm, use a different moveTo().

      Note that there's a baked-in assumption that the only two-arned nmachines will use a group name that is checked against in the 'isOneArm()' method (currently just "arms"). Update this function if this does not describe your use case. It also assumes that groupName "arms" can be described as independent movement of groupName "left_arm" and groupName "right_arm". At this point in time this is a safe assumption because of the state of the PR2's JSON config. point_l, orientation_l refer to the left arm, point_r and orientation_r refer to the right.

      Specified by:
      moveTo in interface ArmInterface
      Returns:
      true on success, false on failure. This function blocks.

    • moveTo

      public Justification moveTo(String group_name, javax.vecmath.Point3d point, javax.vecmath.Quat4d orientation)
      Description copied from interface: ArmInterface
      Move the groupName to a pose. Uses the default coordinate frame as set by JSON (defaulting to base_link).
      Specified by:
      moveTo in interface ArmInterface
      Returns:
      true on success, false on failure. This function blocks.

    • moveTo

      public Justification moveTo(String group_name, Symbol objectRef)
      Description copied from interface: ArmInterface
      Move arms(s) to location of chosen grasp specified in MemoryObject. Uses the default "grasp_point(X)" constraint to select grasp points. Assumes default coordinate frame as set by JSON, defaulting to base_link. Note: gripper should already be open/closed before calling this method. This is an alternative method to moveTo that takes in POWER ref instead of MemoryObject.
      Specified by:
      moveTo in interface ArmInterface
      Returns:
      true on success, false on failure. This function blocks.
