3D Gilbert–Johnson–Keerthi (GJK) distance algorithm

Gilbert–Johnson–Keerthi (GJK) 3D distance algorithm

The Gilbert–Johnson–Keerthi (GJK) distance algorithm is a method of determining the minimum distance between two convex sets. The algorithm's stability, speed which operates in near-constant time, and small storage footprint make it popular for realtime collision detection.

Unlike many other distance algorithms, it has no requirments on geometry data to be stored in any specific format, but instead relies solely on a support function to iteratively generate closer simplices to the correct answer using the Minkowski sum (CSO) of two convex shapes.

Tutorial on how to set up Gazebo simulations of the BlueROV2 (model provided by BlueElectrics), using SITL and ArduSub, and a package provided by kdkalvik for use with mavros.
This folder provides simulation of the BlueROV2 using Gazebo for the dynamics and ArduPilot SITL for the communication and ground control.

Abraham Lincoln once asked one of his secretaries, If you call a tail a leg, how many legs does a horse
have?.
Five, replied the secretary.
No, said the President, The answer is four. Calling a tail a leg doesn't make it a leg.
A group of frogs were traveling through the woods, when two of them fell into a deep pit. All the other
frogs gathered around the pit. When they saw how deep it was, they told the two frogs that they were as
good as dead.
The two frogs ignored the comments and tried to jump up out of the pit with all of their might. The other
frogs kept telling them to stop, that they were as good as dead. Finally, one of the frogs took heed to what
