This is a strange problem. I'm trying to use simulink Ros block to monitor and actuate a robotic arm. After several attempts, the Subscribe block is finally capable to provide real time measures of the robot sensors (Joint Positions).
What I'm trying to do now is to Publish torque command in order to achieve one task.
So I input Sine wave signals to all my joints (fixed array [7 x 1]) just to see what happens when I publish it with Ros Publish Block. From time to time I got a Segmentation Fault in my Robot Ros node, but most of the time nothing happens.
I really don't understand what is the problem.
So anybody experience would be welcome.
