Dawn Robotics Forum

Hi,

I assembled my Raspberry Pi Camera robot but it does not work properly. Sometimes if I start the robot it is partially working (pan/tilt works always, camera does not work right now but can be something else, one of the motors are working). If I start the robot the next time nothing works and this is the log. It seems to me that the firmware was not installed correctly on the first start and now it sometimes tries to install the firmeware again but that does not work properly. Does anyone please have a suggestion? Is there a way to just reset the firmware manually?

Best,
Dirk

Hi there,

Welcome to the forums. Apologies that I've taken so long to reply to this post.

I think perhaps that the bootloader on the mini driver may be corrupt. I'm hoping that your order will have contained a 'programming' cable for the mini driver with 4 built in resistors that you can use to fix the mini driver using the instructions on this page.

If you don't have this cable, or have trouble following the instructions then please let me know, and I'll provide more help.

Apologies that you're experiencing this problem, it seems to be a fairly intermittent problem with the mini driver, which not everyone encounters, but it is annoying when it does happen.

Regards

Alan

Hey Alan,

thanks for the instructions. However, in the meanwhile I was able to "fix" the problem. I formatted the SD card and transferred the operating system again to the SD card because I hoped that on the first start it will flash the bootloader again. And it worked, the problem vanished. Maybe this dirty fix can help other users, too.

The not moving wheel was due to a broken solder joint. The camera did not worked because amazon delivered a broken one... I sent it back and have a working one now.

My robot is fully working now

Next project: Adding infrared sensors and making the robot autonomous The robot is really a very nice toolkit.

If someone has the same problem:

After running the robot for some days the problem returned.

This time I did not want to reinstall a new operating system because I had already installed a lot of stuff. However, I soldered four cables with a 1K resistor and tried Alan's idea. It worked but I needed to unplug the pan/tilt kit and the motors from the board before.
