1.2.0 (2015-12-04)

  • Extended TRAC-IK to both run in two ways: 1) the old mode of first IK solution found causes TRAC-IK to return immediately, versus 2) the new mode where TRAC-IK runs for the full requested timeout duration, then sorts all solutions according to distance from the seed and returns the minimum.
  • Made MoveIt! support this new IK run mode if the user desires.
  • Improved timing info to use a higher solution clock.
  • Fixed TRAC-IK\'s abort/reset of KDL-RR and NLOpt-IK to catch race conditions.

1.1.2 (2015-12-3)

  • Fixed issue where clamping a seed to be within the joint limits might still have values outside the limits.
  • Fixed issue where MoveIt! plugin was not thread safe.
  • Fixed an issue in MoveIt! plugin where error_code passed in uninitialized to SUCCESS could cause IK to say it failed when it did not.

1.1.1 (2015-11-19)

  • Prepared code to have auto test suite run to generate data in main README.md.

1.1.0 (2015-11-12)

  • Improvements to KDL-RR that better handle joint limits on rotational joints that can turn +- PI.
  • Fixed bug where continuous joints could cause problems.
  • Made NLOpt modes enums instead of integer parameters.

1.0.0 (2015-11-10)

  • Initial checkin of TRAC-IK as of Humanoids 2015 submission. Pulled from private repo.
  • Made trac_ik packages conform to rosdep standards.

Package Description

The ROS packages in this repository were created to provide an improved alternative Inverse Kinematics solver to the popular inverse Jacobian methods in KDL. TRAC-IK handles joint-limited chains better than KDL without increasing solve time.

1.4.9 (2018-01-11)

1.4.8 (2017-12-26)
