Twitching Robot

[SusanM]

Has anyone noticed uncommanded motor movement?

Our bot often has random motor movement. We have tried a new location to check for household interference. We have tried multiple transmitters. We are in the process of swapping micro controllers.

Anyone else with this issue or a solution to it?

Thanks,

Is it with motors (continuous rotation) or servos (hold position)?

[SusanM]

It is with motors.

We are also going to try a tether to check for interference with the radio frequency. We are currently testing in a fairly high density residential neighborhood.

We've had issues with twitching when the batteries go low. Perhaps that is the issue.

we've had that problem only once, and that was because another team had their controller turned on at the same time as ours, other wise, twitching motors has not been a problem.

We had this problem when we installed 4WD on our robot. It turned out that the batterys were drained and after a recharge, everything worked fine again.

only time i have seen this problem is when i dont have the controller on at all. btw, on the subject of radios, anyone else notice that it kills television signals that are in the area you are operating in?
