Hello,
how can i control digital outputs with rostopics?
i have following rostopics by start the driver:
/joint_group_vel_controller/command
/joint_states
/pos_joint_traj_controller/command
/pos_joint_traj_controller/follow_joint_trajectory/cancel
/pos_joint_traj_controller/follow_joint_trajectory/feedback
/pos_joint_traj_controller/follow_joint_trajectory/goal
/pos_joint_traj_controller/follow_joint_trajectory/result
/pos_joint_traj_controller/follow_joint_trajectory/status
/pos_joint_traj_controller/state
/rosout
/rosout_agg
/scaled_pos_joint_traj_controller/command
/scaled_pos_joint_traj_controller/follow_joint_trajectory/cancel
/scaled_pos_joint_traj_controller/follow_joint_trajectory/feedback
/scaled_pos_joint_traj_controller/follow_joint_trajectory/goal
/scaled_pos_joint_traj_controller/follow_joint_trajectory/result
/scaled_pos_joint_traj_controller/follow_joint_trajectory/status
/scaled_pos_joint_traj_controller/state
/speed_scaling_factor
/tf
/tf_static
/ur_hardware_interface/io_states
/ur_hardware_interface/robot_mode
/ur_hardware_interface/robot_program_running
/ur_hardware_interface/safety_mode
/ur_hardware_interface/script_command
/ur_hardware_interface/set_mode/cancel
/ur_hardware_interface/set_mode/feedback
/ur_hardware_interface/set_mode/goal
/ur_hardware_interface/set_mode/result
/ur_hardware_interface/set_mode/status
/ur_hardware_interface/tool_data
/wrench
I dont see topic like: set_io - this service i found in documentary, but how can i start it, to publish simple command to activate one of the pin?
set_io
is a service, not a topic, so rostopic list
won’t list it. See the message documentation on how to use it.
For example, the following ROS call would set the digital output at pin 2 to true
:
rosservice call /ur_hardware_interface/set_io "fun: 1
pin: 2
state: 1.0"
If I’m using configurable output Co1, what numeric ID should I use for the pin?
Thank you in advance.
According to our implementation pins 8 to 15 are used for the configurable outputs, so Co1
would be pin 9.
However, that should be documented better!
