  1. ROS Interface
  2. Robot/Client Behavior

This page provides a detailed description of how different robot platforms comply with the Industrial Robot Driver specification. It is intended for developers and systems integrators needing to evaluate specific functional capabilities. More general compatibility information can be found here.

  1. Uses command-line argument instead.
  2. Hardcoded in source code.

  3. Simple Message only supports actual position feedback.

  4. Performs fixed-speed motion set on robot controller. Ignores ROS velocities/timestamps.

  5. Actual position feedback only.

  6. Actual position/velocity feedback only.

  7. Only responds with motion state.
  8. Assumes stepwise motion, from point-to-point, using time_from_start. Does not interpolate between trajectory points using velocities or accel.
  9. Velocities calculated from time_from_start, assuming continuous motion. Ignores trajectory velocity/accel values.

  10. Provides control_msgs/FollowJointTrajectoryAction directly.

  1. Required software downloaded on-the-fly to robot by the Universal Robot ROS driver node.
  2. Error logged. Trajectory truncated at max-size and executed anyway (not ignored).
  3. Trajectory streamed to robot. No overflow possible.
  4. Simulator is single-threaded. Will block new trajectories (buffered in ROS) until previous trajectory is completed, then execute new trajectories in the order received.
  5. Moves through all trajectory points, in the order received.
  6. Topic publishers are always created. No topic messages are published if robot doesn't provide required simple_message broadcast.
  7. Streaming trajectory only. Reaction is robot-specific for robots using downloaded trajectories.
  8. Motion is stopped, drives remain powered.

  9. Socket time-outs may interfere, see ros-industrial/fanuc/issues/19.
