Re: does anyone have OI and RC radio issues

We are having drop out problems with our radio communications too and I thought we had these solved but they came back again....

When we initially had problems with this, our antenna on the robot was within 1 foot away from the drive motors. I then moved it and mounted it on a metal mast which is part of our arm lift mechanism and it was working just fine but now it sems to drop out every 15 seconds or so while driving the robot.

We notice the OI PWM red lights (for the drive motors) are on constant when this happens and sometimes the red No Data/Radio or the No Data lights on the OI light up and stay on for 20 seconds or more while the robot is dead in its tracks. I notice dthat reset clears this and will re-enable the robot.

The green lights on the robot antenna are usually blinking on an off and I have noticed that they do not blink as fast when this condition occurs.

Is this a problem with the RC, the OI, or the antennas?

I am beginning to wonder if this is a susceptibility problem with the antenna unit where we are picking up interference from something else... The location where we are testing the robot has a wireless network, could this be causing some of the problems?

We are also having run-on problems and will load the v14 bin file later today but from what I have read this will probably not fix the drop out problem.

We just wasted a day finding a bind up problem on one of the cim motors and now this is keeping us from the precious time we need...

Any suggestion of how we can over come this problem are greatly appreciated.

Thank you in advance for your advice on the drop out problem.
