Hi everyone,
I assembled the machine in about 2 and a half hours, very carefully and with a very good screwdriver, and I think it's a good project. The manual is accurate enough for me, even if it could be improved, for example it is not marked on which side to hold the connectors of the battery holder. Going back and forth in the images all the information is discovered. Then I came to the software (after reading the theory on the PID controller), on which I worked a few hours, time necessary to understand what were the parts of the program on which I was interested in intervening. I'm a professional programmer in the mechanical field with CNC, but I do not use C ++ for work, and I do not even know the Arduino language. First of all I do not have an android phone so I cut and sewed the program so that it starts in what is called "mode 1", with the aim of making it an interesting "automatic behavior" of the machine. I do not understand how the idea was written in Mode 1, but I think it's wrong. I moved the distance reading from the Setup to the Loop, and I think it's a fundamental change in the logic. However when I loaded the provided code, with eyes closed as they say, the car started to stand .. (loading mode 0) so I do not complain, even if it looks like a shaky old man. Solution 1: put a weight on it;). Solution 2: Decrease P. Actually I think the tremor defect is due to the motor shafts, which move one or two degrees freely. In the next month I will devote myself to testing all the timing and movement parameters, to improve my exploration code. Thank you!

So, I'm trying to find the instructions, but they are so complicated just to find. once I found the instructions, it wouldn't let me open them. Why not have the instructions in the box? it would make this product easier to construct

When I go to "Connect the device" the application can not find the device.
It is well installed, etc.

It promised me to have 2 motor brackets, but I found only one inside the box. Right now the whole setup looks useless to me. Tell me what can I do now without 1 bracket?
