Obstacle and free fall avoidance with mBot Special #ArduinoDay 2016

As you may know, here in Let's Make Robots we are doing something a bit more special for the Arduino Day 2016.

It's not that we are only fans of the Arduino plarform, but we find it very convenient to start robotics, also to keep developing.

To show how easy and fast can it be, I have developed an upgraded version of mBot thanks to our friends of Makeblock.

This new version has some improvements in order to avoid free fall from a table for example:

• Two flowing line sensors at the front to avoid free fall from the front.
• A surprise gesture including wide open "eyes" and noise to show there is void at the front.
• Faster speed.

The software looks like this:

The best is to see the video and how the robot is moving. As always the code is attached just in case you want to test it.
