Algodoo

A robotic car that drives itself. Has 6 sensors. One that stops the car if it is about to crash into something, one that makes it back up when something is heading straight for it, one that makes it speed ahead if something is about to hit it in the back, one that stops it driving off an edge, and two that makes it back up or speed up quickly if something is about to fall on it. I plan to improve it in the future, this is just a basic proof of concept.
Changelog:
v.1 - Initial release
v.2 - Modified the back and falling sensors to prevent it from going forward at the edge of a cliff.
