Lights On Compact Rio?

[Al Skierkiewicz]

excel,
You will find that you will need to see the LEDs on Crio as much as the inspection team and the field controls people. It will be neccessary for these people to see the LEDs in the event of a problem to help you diagnose the problem and a variety of other functions. See p14&15 of the linked document that Russ has provided. If any of the volunteers has a hard time seeing any indicator on your robot, it will make it difficult or near impossible to help you troubleshoot and you may be asked to move it. All indicators are there for your convenience so put them where they can be seen.

<R58>
ROBOTS shall use the diagnostic Robot Signal Light provided in the Kit Of Parts. It must be mounted on the ROBOT such that it is easily visible while standing three feet in front of the ROBOT in the STARTING CONFIGURATION.

The team has no direct control over the light and no programming is required.

Russ also provided this document in a different thread. It is an explanation of the RSL codes...
