Hi Pete,

Regarding your battery issue, my first suggestion is to check the front UI-powerbase wiring harness. Ensure that it is properly tightened, and then check for any damage that may have occurred to the connector. If the connector looks ok and the lights remain red, try swapping the positions of the front and rear wiring harnesses. If there is an issue with the harness, the red lights should remain in the front position.

If, however, after swapping positions of the harnesses, the red lights change position, there is likely an issue with the batteries themselves. Return the wiring harnesses to their original position and remove both batteries from the front powerbase. Reseat the battery packs and torque the fasteners to 1.6NM. Once again, plug the RMP in to charge and observe the battery indicator lights. If they remain red in the front position, remove all four powerbase batteries. Install the original front batteries on the rear powerbase, and the rear batteries on the front powerbase. Plug the machine back in to charge. If the red lights now appear in the rear position, there is very likely an issue with the battery packs. Try replacing them with new or known-good packs. If the red lights remain in the front position, there may be a problem with the charging electronics.

If you have any questions, or if I was unclear, please feel free to give me a call at 603-222-6309.

Thanks,

To add to Andrew's reply below, If the charger is plugged into the machine when you power it on and the DISABLE_AC_PRESENT_CSI bit is not set in the configuration bitmap the machine will fault (due to the charger being plugged in). This feature is to prevent a user from commanding motion while connected to the wall, and is configurable if the user wishes to disable it.

If you continue to have issues please visit:

This walks you through extracting the faultlog with a non-ocu program designed to allow users to pull the log without the OCU.

trautman,

Patrick has ported the Demo OCU to linux. It hasn't undergone much testing yet, but should work on Ubuntu 12.04. http://rmp.segway.com/viewtopic.php?f=9&t=83

Please keep us informed with your progress on getting the RMP to work with ROS. The work you do may be helpful to others in the community.
