This example can be tested with the simulated hand (or simulated hand and arm) by using the following commands in separate terminals *
* roslaunch sr_hand gazebo_arm_and_hand.launch * or * roslaunch sr_hand gazebo_hand.launch * and then * rosrun sr_example link_joints * rosrun rqt_gui rqt_gui
in the rqt_gui go to plugins->ShadowRobot->joint slider and select EtherCAT hand If you move the joint slider for FFJ3, then MFJ3 will move as well.

Function Documentation
| void callback | ( | const control_msgs::JointControllerStateConstPtr & | msg | ) |
The callback function is called each time a message is received on the controller
- Parameters:
-
msg message of type sr_hand::joints_data
Definition at line 84 of file link_joints.cpp.
| int main | ( | int | argc, |
| char ** | argv | ||
| ) |
The main: initialise a ros node, a subscriber and a publisher
- Parameters:
-
argc argv
- Returns:
- 0 on success
init the subscriber and subscribe to the parent joint controller topic using the callback function callback()
init the publisher on the child joint controller command topic publishing messages of the type std_msgs::Float64.
