this did the trick to get the gpio_control.py working.I also had to run through some hoops to get flask up and running. sudo apt-get install build-essential libssl-dev libffi-devython-devand also had to sudo pip install flask_ask as well

LOL, this worked for me too. It seems that Alexa can't understand foreign languages like english ;)I duplicated the instructions in the add a language tab, now Alexa can understand english as well :)

See above for setting your echo to the language "English (US)" perhaps? If you are in the UK or elsewhere, then you also have to add languages to your setup.

which gear ratio did you decide on?

What kind of joystick is that? All the ones I've found so far have resistance across an asymmetric range which is very small. Basically not really spot a and only perform as a switch in reality.

nice idea, will try that in another tracked robot I have. For this the servos are opposed driving the front and rear on each side so they are both aligned.
