Dawn Robotics Forum

Hi, I sent a message yeterday about my Raspberry Pi Camera Robot not working (no movement of the camera pan/tilt or the wheels, but the camera stream works fine). I have since gone onto the log (192.168.42.1/logs.html - *) and realised the Pi is not communicating with the mini driver. Also from reading other threads, I see that I should expect to see a blue light flash when I power on the mini driver, however I do not see this - it is just red the whole time.

Please help me ASAP. I am a Secondary school teacher and had promised sessions to primary school students this week where they can come in and move the robot around an obstacle course and don't want to keep dissapointing. This is the reason we purchased the robot. It is so frustrating because it was working absolutely fine on monday morning, then just decided to have no life in its motors the next time powered on and nothing was changed at all.

*Here is the log:

Dear Mark,

Very sorry to hear that your robot isn't working, apologies for the delayed reply, I've been ill and only just got to this forum post.

I am so sorry that we've let you down in this way, and that there isn't time to get the robot working before your open evening this week. If you are planning to run other sessions this week then please let me know and perhaps send a phone number I can call you on to helpdesk@dawnrobotics.co.uk. I can get spare parts/or cables to repair this problem sent out by Royal Mail special delivery tomorrow which would give you something for Thursday/Friday.

Regards

Alan

Hi Alan

Thanks for your reply. I have the main open evening on Thursday this week wherev all of the year 6s and their parents are in school so if I could get it working for then, it would be great as they would get a chance to see the robot working. My phone number is 07973428941 - feel free to call me day or evening asap. Does the fact that there is no blue light when the mini driver is powered on mean the mini driver is dead? Evertyhing was working fine and then suddenly was not even though nothing was changed so I dont think its a firmware version issue either. I have tried writing a new SD card image to the SD card from your site, but still the same problem.

Thank you again

Mark
