  • Getting Started with OpenRAVE environment. Guidance could be followed at Stéphane Caron's blog.

  • Error may be frequently encountered during compile. Alternatively, docker image is recommended.

    Docker setup

  • Check personalrobotics/ros-openrave

    sudo docker pull personalrobotics/ros-openrave:latest
  • Since the image is pre-built, no need to docker build with Dockerfile. Just run it. Mirror the /root/data to your current workspace.

    sudo docker run -it --rm -v /home/dingyi/workspace/dingyi-code/side-project/openrave-test:/root/data --network host ada6b60e98b7 bash
  • Where image id ada6b60e98b7 could be obtained using sudo docker images.

    Closed-form solver generation

  • Now go to /root/data in the docker image will direct to the same workspace.

  • xmlfile like ur5.robot.xml represents the robot model. Use ikfastpy to generate the ikfast solver.

    python `openrave-config --python-dir`/openravepy/_openravepy_/ikfast.py --robot=ur5.robot.xml --iktype=transform6d --baselink=0 --eelink=6 --savefile=ikfast61.cpp --maxcasedepth 1
  • It takes several minutes to generate the closed-form ikfast solver, which is a cpp file named by you. Then ikfast61.cpp is shown in your workspace.

  • Now you can exit the docker image.

    Test the solver

  • Compile the ikfast solver using gcc(need -llapack).

    gcc -fPIC -lstdc   -DIKFAST_NO_MAIN -DIKFAST_CLIBRARY -shared -Wl,-soname,libik.so -o libik.so ikfast61.cpp
  • libik.so comes out in your workspace.

  • Compile the executable demo for testing purpose.

    g   ikfastdemo.cpp -lstdc   -llapack -o compute -lrt
  • Run compute for easy tests for fk and ik.

./compute fk -3.0, -1.6, 1.6, -1.6, -1.6, 0.0
./compute ik 0.457016 0.172972 0.434512 -0.001461 0.755053 -0.655338 0.020595
  • Verify your results with the real robot.
