RGB Value to Nearest Color Name (Python)
"""
Original Author Ernesto P. Adorio, Ph.D
Original Source: http://my-other-life-as-programmer.blogspot.com/2012/02/python-finding-nearest-matching-color.html
Modifed By: JDiscar
This class maps an RGB value to the nearest color name it can find. Code is modified to include
ImageMagick names and WebColor names.
1. Modify the minimization criterion to use least sum of squares of the differences.
2. Provide error checking for input R, G, B values to be within the interval [0, 255].

Comparison of ZeroMQ and Redis for a robot control platform

ZeroMQ vs Redis

This document is research for the selection of a communication platform for robot-net.

Goal

The purpose of this component is to enable rapid, reliable, and elegant communication between the various nodes of the network, including controllers, sensors, and actuators (robot drivers). It will act as the core of robot-net to create a standardized infrastructure for robot control.

Requirements:
