Bot Board II Problem

asiek001 · March 6, 2009, 12:19am

Recently purchased a new Bot Board II from lynxmotion after somehow accidently ruining the old one somehow. Received the new one, installed the basic atom and programmed it fine, but the board does not seem to respond to any commands.

The Basic Atom Pro seems to accept the program, the board chirps when it is powered on, but the green LED turns on stays solid, and the yellow LED blinks, and no response from the first red? LED, also the power LED is solid.

The PS2 receiver has 1 solid light on and the other light on it does not light (Lynxmotion controller)

Everyone’s going to need more information in order to help you.

You should probably post the code that you’re using, Maybe there’s a problem with that. Or if you can you should make a video of what the board is doing and take some pictures of your boards connections. Remember…pictures are worth a thousand words!

Edit: My controller is doing that same thing, and I have the old Atom Bot-Board. Does the Controller turn off when the Receiver turns on? If so, you seem to be having the same problem I was/am.

Edit #2: Oh, DUH! I forgot you can’t post images or videos until after like 48hrs. or so.

asiek001 · March 6, 2009, 1:29am

the controller does do weird things like turn off magically and have to power up again in order to work, usually when its idle, the problem still happens with the receiver not plugged in (the board problem)

wowy7 · March 6, 2009, 1:34am

Huh…so you’re saying that the controller powers down by itself even when the receiver isn’t on? that’s odd. I don’t think mine does that. Do you have the pins connections updated (i.e. connected differently from your last board)?

kurte · March 6, 2009, 1:36am

Hi Asiek,

Things to check:

Battery, what power do you have hooked up to VS and VL? Assuming battery or Batteries, are they charged. I have spent more time then I would like to admit tracking down problems and find out it is my VL 9v battery going dead…
More likely: check your jumper settings. I normally have better luck with a PS2 controller when I remove the jumpers for the LEDs and buttons.

asiek001 · March 6, 2009, 2:05am

i have a 7.2 V going into the VS, with 2 servos connected with the VS jumper, and the 5v jumper with the receiver…i will try removing the LED jumpers and see what happens. I have both boards in my possession so i compared the jumper settings and they are were the same.

It could possibly be the battery (hopefully that is the issue), its an older battery, it worked with the old board but since i am guessing the battery got short circuited and burnt the old board’s terminals, so it may have damaged the battery too

wowy7 · March 6, 2009, 2:28am

Please take a look at this: lynxmotion.com/images/data/bb2pdf.pdf

It will tell you how to correctly connect the receiver to the Bot Board II.

If you have already looked at that and everything is connected properly then it must be the battery.

asiek001 · March 6, 2009, 2:33am

i checked the jumpers and everything seems fine, i am going to go out tomorrow and purchase a new battery after checking all the wires first…i will post updates as they come, thanks for the help so far everyone

wowy7 · March 6, 2009, 7:14pm

asiek,

I was just able to get my PS2 controller to work by opening up the plastic shell on the receiver. I don’t know how, But the led starting blinking and I turned the remote on and it was working. I still don’t know what the problem was but its working and that’s all that matters.

Good luck!

asiek001 · March 7, 2009, 6:22pm

i just got access to a computer to reprogram the Basic Atom Pro (linux doesn’t like it)…reprogrammed it to not include anything with the PS2 and i got the motors to spin and everything that i wanted. Which leads me to believe that either 1) the remote/receiver is bad or 2) the actual connector to the board is bad … is it possible that the battery could still be an issue here or is more receiver / controller related? i am going to test it on a PS2 when i get the chance, which will be within the next day or so and if it works on there i can assume its the connector to the board? Using LM controller/receiver etc etc

kurte · March 7, 2009, 7:33pm

It would be good if you could verify that the PS2 controller works by plugging it into a PS2 machine. If that works then we know that works. Also try fresh batteries in the PS2 as this has hurt me in the past.

It would probably help if you could post a picture of your board with a closeup of the area where the PS2 plugs into p12-p5 so we can see if your wires are plugged into the right pins, also that you have the power jumper set properly for those pins, such that you get power to the ps2. Likewise that you have removed the other jumpers from the buttons…

Kurt

wowy7 · March 7, 2009, 9:11pm

Not everyone has a PS2.

As I said before, try removing the 4 screws on the receiver. It helped fix mine and my batteries where still almost dead.

robotdude · March 9, 2009, 2:42pm

Please remove the jumpers for the LED’s and switches. They aren’t used and could be trouble.

The PS2 controller will turn itself off after it has been idle for a little while. This is normal. It will also need to be reset if you walk too far from the bot with the controller. It’s 2.4ghs so humidity will affect the range. It’s generally good for 35 feet, but in low humidity conditions it can be well over 60 feet.

asiek001 · March 10, 2009, 2:12pm

Thanks for the help everyone, it ended up just being a bad controller, which explains the blinking that is part of the program, after testing it on a PS2 and connecting a wired controller to the Bot Board. Weird how it just went bad like that after working so well…anyways time to get a new one. Thanks again
