I remember the day when I was gifted a toy robot. Blinking with
colorful lights the robot was moving all around emitting digital sound...
     A robot is a mechanical or virtual agent, usually an electro-mechanical
machine that is guided by a computer program or electronic circuitry.
A robot can walk (even on moon), swim and even fly. Robots form  the
backbone of any industry. Some of the first robots were put to use in lifting
 hot metal pieces from the furnace. The robotic arms help reduce workload
more than one ever imagined...There are all sorts of robots such as humanoids,
soccer playing robots, industrial robots, reading robots, microscopic
nano robots and much more.. The surgical robots perform high precision
operations at the touch of a remote. The cleaning robots with collision
sensors perform sweeping and mopping at a voice command...
The reading robots have replaced teachers and even interact with
students and respond to queries in speech. Artificially intelligent robots
also aid in thinking and logic.
There are sms composer robots, blogger robots , emotionally commenting robots, chatting robots , memory robots and presentation robots.
A truly science wonder,  robot indeed is a loyal friend. ..
