Hello everybody. Firstly, i wanna say sorry for my English. I have several questions and hope that you will help me.
Not so far ago, we had a competition in Moscow and faced with a big problem.
The field was freezing and lagging ( you press the button or stick , and after many seconds robot starts mooving). The main judge said, that it is our problem because our Teleop programms are not multithreads. But when we had a competition in our region with a simple D-link router, everything was fine.
Now i'm afraid , that in the nearest competition in Moscow we will have that problem again .That' s why , i'm not so sure that he is right about multitasking?
And 1 question more.
With a d-link router our robot were disconnected from the field seems that power supply were switching off time to time. Could it be because of static electricity? (Cuz we were always shocked by it , when were touching it)
