[right_arm_ctl-1] process has died

[zt-yang]

Dear Movo support team,

I'm a researcher using Movo robot and recently stuck at a ROS error that says the right arm control process is unable to launch (when we roslaunch movo_bringup movosystem.launch, see the screenshot attached). We'd appreciate your advice on how to locate the source of the problem, or if you could refer us to the team that might help us. We know that the power is connected because we see the red light on the right gripper. Thank you!
