# MoveIt Simulator Controller A simulation interface for a hardware interface for ros_control, and loads default joint values from SRDF Intended to replace ``moveit_fake_controller_manager`` - this repo almost exactly replicates a ros_control hardware setup, and has the new feature of being able to specify an inital position. <img src="https://picknik.ai/assets/images/logo.jpg" width="120"> This open source project was developed at [PickNik Robotics](https://picknik.ai/).

You can change the start position by editing in ``config/ur5_controllers.yaml`` the value ``joint_model_group_pose``. With this simulator you should also be able to use ``rostopic echo`` to see the ``joint_states`` and ``tf`` it is publishing - essentially you have just simulated a full ros_control-based robot without needing hardware. To test with an example joint trajectory, see the demo code in [ros_control_boilerplate](https://github.com/davetcoleman/ros_control_boilerplate). ## Usage To set your robot's initial simulated position, create a *planning group* in your SRDF using the *MoveIt Setup Assistant* named something like ``whole_body`` or ``arm`` that contains all of your robot's joints. Then, create a *pose* for the planning group that is your start position, and name it something like ``home``. Then load this node with the following ROS params (yaml is suggested use): # MoveIt-specific simulation settings: moveit_sim_hw_interface: joint_model_group: arm joint_model_group_pose: home See [ros_control_boilerplate](https://github.com/davetcoleman/ros_control_boilerplate) for more detailed instructions about using ros_control to visualize your robot - this package simply inherits from that package and adds some MoveIt! dependencies that can parse SRDFs for your initial state. ## Testing and Linting To run [roslint](http://wiki.ros.org/roslint), use the following command with [catkin-tools](https://catkin-tools.readthedocs.org/): catkin build --no-status --no-deps --this --make-args roslint To run [catkin lint](https://pypi.python.org/pypi/catkin_lint), use the following command with [catkin-tools](https://catkin-tools.readthedocs.org/): catkin lint -W2 There are currently no unit or integration tests for this package. If there were you would use the following command with [catkin-tools](https://catkin-tools.readthedocs.org/): catkin run_tests --no-deps --this -i ## Contribute Please send PRs for new helper functions, fixes, etc!
