Technology and its simple applications

Making life easier for humans is a goal of any technology. Or rather put differently, technology is as good as it can be put to the effective use by humans. There are many technologies that have been and are shaping our lives daily. The one I recently came across is the iRobot Roomba. Roomba is a great technology put to very good use by delegating chores to intelligent robots. I recently brought one and it works great. The amazing feature of this device is that it has a detection mechanism to cover the whole room. The company was founded by some robotics engineers from MIT. They have robots for government and industrial applications and for home environments. The Roomba series for home environment are available for various purposes such as  cleaning, scrubbing, workshop cleaning (this one is my personal favorite), a pool cleaning and gutter cleaning robot. One sees robots regularly in childrens toys but I have seen a practical application so apt for the first time.
This is the description on their website:
iRobot designs and builds robots that make a difference. iRobot was founded in 1990 when Massachusetts Institute of Technology roboticists Colin Angle and Helen Greiner teamed up with their professor Dr. Rodney Brooks with the vision of making practical robots a reality. iRobot stock trades on the NASDAQ stock market under the ticker symbol IRBT.
