Fable points north
The Fable robot is set to point in the direction of north, according to the input it gets from the magnetometer in the smartphone.
- Smartphone with Fable Face (get it from App Store or Google Play)
- 2 passive modules
- 2 joint modules
- 1 phone holder
- 1 lid
Set up the Fable robot as a social robot with 2 arms and the phone in the phone holder (watch the video).
Find out which way is north with a compass or google maps.
Program in Fable Blockly so it looks similar to this:
The magnetometer goes from 0 - 360 degrees but the Fable joint module only goes from -90 - 90 degrees. Therefore the robot is set so that the left arm goes from 0 - 180 and the left arm goes from 180 - 360, so that when you turn the robot around - first the one arm will move and then, if you turn it all the way around, the other arm will move.
