Hi all,

 

I'm Zeon. Recently I got problems reported by pr2_dashboard such as IBPS 0-3 missing, smart battery 0.0-0.3  1.1-1.3  2.0-2.3  3.0-3.3 missing, c2 CPU Temperature & usage & HD Temperature missing, joystick stale, laser stale, clocks error. The diagnostics is shown below to illustrate all the problems. 

 

 

Here are some attempts:

1.     ssh c1 and c2: succeed. I mean c1 and c2 is good respectively but on c1 I couldn’t get c2 CPU usage and temperature information.

 

2.     on c1, ping c2(10.68.0.2) c1 BMC(10.68.0.91) and c2 BMC(10.68.0.92): succeed

 

3.     teleop_keyboard is OK but teleop_joystick doesn’t work while teleop_joystick successfully setup in base station. Lights on joystick keep flashing which means joystick doesn't connect to robot, maybe the bluetooth on c2 doesn’t response.

  

4.     I guess maybe something wrong with the power board so I moved the back cover and take pictures of the power board which is shown as below:

 

5.     I also searched some similar problems like this page which says everything goes well after install pr2-* and ros-groovy-pr2-*. But it doesn’t work on me. I’ve installed most packages of pr2-* and ros-groovy-pr2-* except for some broken packages. Another page says it maybe caused by the device symlinks got messed up. So I open the pr2 server to check the links of connections according to the Toolkit Doc32 Server_remove_replace. All the links on c1 and c2 are alright but there’s one line called c1 BMC is disconnected at the other end(I mean one side on c1 while the other end is disconnected). And I found the ports between the c1 and c2 is like this:

 

• port16: Ethernet WAP
• port15: Ethernet Right Comp Port 1 of 4
• port14: Ethernet Right Comp Port 2 of 4
• port13: Ethernet Right Comp Port 3 of 4
• port12: Ethernet Left Comp Port 2 of 2
• port11: Ethernet Left Comp Port 1 of 2
• port10: Ethernet Power Brd
• port9:   Ethernet Left Arm Camera
• port8:   Ethernet Right Arm Camera
• port7:   Ethernet Gigabit Camera
• port6:   Ethernet Stereo Camera Lower
• port5:   Ethernet Right Comp Port 4 of 4
• port4:
• port3:   Ethernet Head AUX Lower
• port2:   Ethernet WIFI
• port1:   Ethernet LAN Service Port

 

On which you can see port4 is disconnected. After I connect c1 BMC on port4, it doesn’t work.

 

6.     c1 Aux is disconnected

 

 

Did anyone meet similar problems or can help me out? I’ll be appreciated to receive your reply.   :)
