Does anyone see the RSL (Robot Signal Light) flash in the video? I am not seeing it flashing or are momentarily blind (or both). The jitter could be a low battery undervolting the sidecar, but without the Log file, it is just speculation.

Any FTA's, FTAA's, CSA's, or anyone else are more than welcome to throw out other ideas.
I can try and get the logs on thursday when I get to the robot again and try and upload them. The rsl is not blinking because of a broken connector which is on the list of things to fix. I do know that when it does jitter the voltage goes down to around 4.5, which I could see messing with the sidecar. I will check to make sure all the cims are working properly as well.
