I am using DSC controller and trying to communicate with the Dynamixel AX12A servo motor from my RasPi 3B. I have followed the steps described in the following link
I have also configured the con.yaml file as mentioned in the above link. I am able to run the dsc.launch file and also the serial_node in rosserial_python. When I check the /mydata ros topic, all the values are -1. But I have connected a servo motor to the second slot. Can you help me with that?
I am using the ubiquity linux image for my RasPi
