Radio/RC Problems for 2007 Season

[roborat]

We had the same problem with the radio losing signal when we were on the other end of the field. We changed the position of the radio on the robot and changed the cable just in case. It has not given us any problems since that move. It was lying flat beside of the backup battery and we moved it to the arm support and protected it with a cover.

Count us as having a lot of mysterious radio disconnect problems this year.
Team 1001.

In some cases we have been able to find something to blame it on (like having some other team on the same channel, or low batteries, etc.), but even when all those issues are resolved we are driving merrily along, the radio link fails, robot stops, toroid deposits on ground. sigh.

I guess that is an unexpected benefit of having the claw in the closed position when power is off? we set it up that way for autonomous

Last night we had the robot take off pretty fast, out of control....on pretty much our only attempt to use the new radio. Finding a place to put the radio upright on the robot, away from metal, and always in LOS of the OI radio, is quite a challenge! but seems to be unnecessary when using the 2006 radio.

As posted in the previous thread (now bumped off the front page), our team had the same radio issues others have experienced. We sent the radios back to IFI, they reported nothing major wrong with them, but since getting them back we have had no further problems with cutouts. Last night/early this morning we drove the robot around full tilt, all mechanisms operating, and did not experience the same problems we had originally.

IFI is only capable of "pro-action" if you report problems to them. Let's face it, people post to a forum only if they're are having trouble, not if when they figure out the problem and everything is ok. Unless you call them and officially let them know something is wrong with your equipment, I would not expect them to continually refresh CD and write down the team #'s for everyone who has had a problem.

True, but they certainly knew there was an issue with the code for the cut-off. They released a new version of the Robot Controller Master Code. Part of my point is that this should either be declared working and no longer in beta, or they should have (by now a long time ago) released a new version.

This slightly bothersome radio issue has now almost cost us our arm/tube interface. We jammed a denso and keyang against hard stops. I'm suprised we didn't strip out the worms in them. When controlling the arm with 2 potentiometers for our 2 articulations the thing just suddenly took off like a rocket, not listening to disable, and after some very scary noises, finally listened.
