RaspiDuinoRover - (Yet another) Raspberry + Arduino rover

Wed Jan 15, 2014 11:04 am

Hi all,

I just wanted to share a work in progress project about a Raspberry Pi + Arduino Pi rover. This rover is iPhone remote controlled, and provide an MJPEG stream from Raspberry Pi camera module.

Very nice, I really like the app, instead of using just a web interface or something like that :P

:mrgreen: Hi. I like making robots and robotics with the Raspberry Pi :lol:

Thanks.

I tend to prefer native apps to web apps because I think the first ones have more potential than later ones. And as an iOS developer, it was a natural choice for me :-)

I certainly agree about them having far more potential than web apps. The only problem for me is that I have no experience in developing for iOS :lol: . Anyway, really good rover :mrgreen: !

Hey
first of all NICE WORK!
i'm trying to do a similar project, a quadruped driven from android device with face detection included. I still didn't got a chance to view your files but i was wondering is using USB serial to connect RPi to the arduino is better than I2C?

Thanks :-)

I don't know if it's better or not. Using USB to serial have the advantage of powering the Arduino board. But with camera module, WIFI adapter and Arduino on USB to serial, you will be very close of maximum current usage allowed by the RPi (700 mA) if you power it thought its micro-usb connector (but you can power it thought its GPIO pins, bypassing the 700 mA polyfuse).

From a communication protocol point of view, I find I2C less verbose than serial, but its just my humble opinion :)

maybe because I dont like I2C that much :D had some problems with it when I was using microcontrollers not arduino plus i won't have all those wires :P
anyway i guess you can use more than 700 mA for RPi , found some projects on net using current up to 1.2 A and i'm using 850 mA from my mobile charger.
here's a project similar somehow to yours but using serial connection and tornado web server https://github.com/salendron/RaspDuinoPowerSwitches

If you use micro-usb connector (a.k.a don't bypass 700 mA polyfuse), you are "guaranteed" of no voltage drop after the polyfuse. If you use more than 700 mA, you may suffer voltage drops, and even more if the ambient temperature rises.

And I2C needs only 2 wires :-)
