Certain routines such as Teleop need to return quickly or they will cause you to miss joystick packets. If these are OK, look to either feed more often or adjust the period so that it doesn't expect to be fed any more often.

Remember. The user watchdog helps you know when your code isn't running as often as you thought it would, and gives it a way to fail safely when certain mistakes are made such as crashing or infinite loops.

We're using iterative robot template.. so do we put it in teleop periodic?

Here's our code... if anyone's intersted
