Avrdude stk500_cmd() programmer is out of sync

#1

We purchased the Robot starter kit. I downloaded the mblock software and installed the code to run it via bluetooth. All worked OK. (Although the bluetooth constantly disconnects, but that is not what I need help with).

We wish to build the voice controlled robot at this link: http://www.instructables.com/id/Smart-Robot-with-Vision-and-Voice-control/

When trying to upload the Arduino code they have published there we get “stk500_cmd() programmer is out of sync”. This seems to be a fairly common problem but I have not found a clear solution documented online. Can anyone please give some idea on what might be wrong?

Did you upgrade the firmware from the Makeblock IDE? You have to be connected via USB cable to do so.

There was a similar problem (link) and that seemed to fix it by updating to the current version of the Makeblock libraries (link) if you are going through the Arduino IDE.

Hi Chuck

Thanks for getting back to me. I did have the latest libraries installed. But the code that was published online was wrong. I think that was the problem, as when I changed that based on their recent response on the instructables forum it worked.

I managed to build their voice controlled robot using droid script, a Samsung s6 and the starter robot. But my phone doesnt seem to respond well to the voice prompts…therefore the robot doesnt. I have been doing alot of research into different solutions, and I think I am going to try using a Raspberry Pi and connecting it to the robot using the USB port.

Cheers!
