I came across the instructions to build this in a magazine and found it a great entry into robotics. It is working well but I'm still fine-tuning the programming. I would like to add to this project over time, to eventually include voice control, speech and other nice things. For…

Connecting the ultrasound I have a similar design but with 4WD using adafruit motor shield. I would like to know how you connected the ultrasound because i have nothing to connect to on my motor shield which is on top of my arduino uno. Any other pix of your project will appreci…

ultrasound sensor problems since my last post I have been playing around with the programming of my beastie and am now thinking that most of my problems (getting stuck in corners , going towards obstacles) have very little to do with the software but with the unreliability of th…

I have a bot that is almost I have a bot that is almost exactly like this, that I built to play around with code on before intergrating ‘intelligence’ into my large mobile platform. One thing I noticed, is when running the arduino off a 9v battery, and the motors off 4 AA batter…

If I recall, I had to solder If I recall, I had to solder pin headers to my motor shield. The spot is there for them, you just need to solder them on.

Sorry, haven’t been roboting for a while :frowning: I have now changed the setup to run the motors from 4xAA batteries and the Arduino with a 9V and this seems to work better. I have also completely rewritten the software and made it a lot simpler - and now it actually works! It…

Test Bench Test Worked I put my components together on the test bench today and copied and pasted the code into one of those super cheap clone UNO R3’s with the 340 USB to TTL chips on it and used the russian driver to get it to work and all went to plan, the motors were powered…

hi, I am actually using a DK

hi, I am actually using a DK Electronics motor shield, not sure whether that is different to the adafruit. The ultrasonic sensor is attached with 4 dupont wires that I soldered onto the analog pin rails near the M3 connectors (bottom left of photo).

The connections are:

sensor Vcc - Trig - Echo - Grnd

Board +5 - A4 - A5 - Grnd

Hope this helps.
