I just bough a 3WD omni-directional arduino compatible robot, and I am trying even now, using the arduino software, to upload some sort of program on it. It seems the problem lies in choosing the correct board in tool>board, but I’ve tried all the logical choices and the code doesn’t upload, (the board is not a standard arduino and manufacturer did not mention which selection to use). If anyone has any suggestions, especially those who have bought this kit, please let me know.
Here is information we’ve obtained from the manufacturer:
Attached are a picture of the Arduino board selection and sample code and documentation from the manufacturer.
Let us know if this helps with your issue.
