Hi Alan

Still no luck I am afraid. Have tried that zip file and ran the commands from the command line. There were some errors:

Reading | ################################################## | 100% 0.60s

avrdude-original: verifying ...
avrdude-original: verification error, first mismatch at byte 0x0000
0x3f != 0x00
avrdude-original: verification error; content mismatch

avrdude-original: safemode: Fuses OK

I tried the robot just in case, but still the same problem. The log page shows exactly the same as before. Is it best to just try the update to the latest software from the bitbucket repository so it can find and connect to firmware 0x31?

Hi Mark,

Yes, that's a good idea. To update the software you need to log into the Pi, and run the following commands from the command line

Code: Select all
cd /home/pi/raspberry_pi_camera_streamer
git pull
cd build
make
sudo make install


Code: Select all
cd /home/pi/raspberry_pi_camera_bot
git pull


The first batch of commands will update the camera streaming program, and the second batch will update the robot web server. If you reboot after running the commands your robot should hopefully work (umpteenth time lucky?)

The main thing to watch out for is to check that there are no build errors when running make for the camera streamer.

Regards

Hi Mark,

That's great news. :)

Let me know if you want to change the software on your mini driver at some point and I can try to give you some more help with unsticking it.

Regards

Hello,

My son and I recently acquired the Dawn Robotics Camera robot and have spent the last few weeks getting together. A few problems with the SD image but eventually flashed the card with the latest (2015-02-10-dawn-robotics-raspbian.img) and Big excitement last week when we got the robot to move around the room. We received and fitted the PI camera Yesterday and again Big excitement when we got streaming pictures :D .

Now this is where we hit a snag, not too dissimilar to the one described in this post but at the same time we are not sure its is the same problem. We can stream the camera but don't get movement from the wheels or the camera mount. If we disconnect the camera and reboot then movement is restored.

Any ideas on the cause? And a fix?

Hi there,

Firstly, welcome to the forums, and secondly, please accept my sincere apologies for the massive delay in seeing and responding to your support request. I don't get a notification from our forum software if a first email is waiting to be approved, so only saw your post by chance when looking at some of our older posts. I think this is the longest delay we've had though so I'll push the 'look for new forum software' up my todo list.

Anyway, if you haven't given up on your robot, and would still like some help. If you navigate to 192.168.42.1/logs.html then you should get logs from the running robot. If you could please post the logs here then I can look to see if there's anything that might be causing your problem.

Regards

Alan

Hello Alan,

Thank you for your help. After much reading of other posts and a bit of trial and error we solved the problem. The batteries were not providing enough power to the combined system! We confirmed this by powering up the Pi on a power lead and then went out and bought some Maplin 2400mha rechargeables. These also did their job but don't seem to last that long. We have noticed that as battery power runs down one of the first things to stop working is the wifi. Wasted a bit of time at one point troubleshooting the arduino drive connection before realising that it requires a separate power source (ie batteries) from the Pi if the Pi is powered with the lead, obvious really!

Anyway, it seems to be working OK and are now trying to use python to program movements. Got some basics movements working, but still playing with the commands to understand what works and what doesn't. It's a cool toy! :D
