We are two french students who make a work placement in Poland and we should made some differents tasks.
We have ever built a robot Phoenix 3DOF without problem. Assembling, programming, using PS2 pad on the Bot Board II.
Now we build a second robot, it’s exactly the same, configuration and etc…
But we have a problem with the power of Bot Board II. The BBII is correctly connected to SSC-32 and when we plug the battery (9V). The LED which show the power on BBII doesn’t light and the the card heat faster so I stop and disconnect the battery.
Could it be a problem with the made of the electronic card ?
We built the Phoenix 3DOF with SSC-32 and BBII and PS2 pad.
Without the BBII we can control correctly the robot with Lynxterm.
Then we followed this picture to connect the two cards. But the 9V battery is connected only on the BBII. That’s work on the first robot.
The jumpers are installed like this picture:
With this configuration on the first robot it’s works perfectly, but on the second robot when we plug the 9V battery the LED power on BBII doesn’t lighted.
Make sure you double check the polarity of the battery and make sure you didn’t shorten anything on the board. Sometimes it helps by disconnecting everything and build it back up bit by bit. Check if everything works after every connection. Start with the power connection so you know for sure that that part is right.
I check all, the configuration is the same which is indicated on the datasheet, the connections seem to be ok.
I add a picture of the robot but it’s not a good quality. But we respect the connection of Lynxmotion’s datasheet.
The component you’re pointing out isn’t a transistor, it’s the voltage regulator. A voltage regulator getting hot most of the time tells that the polarity is reversed or you’re drawing to much current. Make sure the polarity is ok by checking it with a desent multi-meter. And check the board for any short-wiring. You could also check if the regulator gets hot when you disconnect everything and even remove the BAP.
I’m also having trouble with the voltage regulator heating up.
I’ve narrowed it down to what I believe is the power supplied to the PS2 controller being the problem. I’ve noticed that I have an extra wire on my PS2 controller breakout that isn’t on the drawings.
The drawings show there being only a yellow and a red wire for the power, but I have an additional black wire in the same pin as the yellow. I’ve used my amazing MS Paint skills to try and illustrate this: http://img830.imageshack.us/img830/1765/61107425.png
Is this how it’s supposed to be? When I plug in the power cable it seems like there’s a short as the power light on the bot board goes out and the voltage regulator starts to get pretty hot, pretty quick. Changing the plugs isn’t a problem for me, I just want to make sure I know what to change them to first.
