Robotics Inching to Make Robots More Human-like

It’s a common misconception that robots should be like humans. Actually, if they did, it means compromising their potential as a computing machine capable of processing billions of instructions per second while asking fringe benefits and leave benefits from their employers.
It’s a common misconception that robots should be like humans. Actually, if they did, it means compromising their potential as a computing machine capable of processing billions of instructions per second while asking fringe benefits and leave benefits from their employers.

We’ve seen movies portray robots of the future with terms like "humanoids" or “Cyborgs” that stand for cybernetic organisms. There’s rarely much truth in them. Robots today are mostly stationary machines with tentacular armatures that perform multiple and often simultaneous tasks that churn out complete cars, trucks, appliances and motherboards and other complex electronic circuits.

But the objective remains to impart human-like quality in robots at least in the areas of stable mobility and cognitive interactivity for robotic science to consider

Human Interaction

The cognitive ability to respond and elicit response with humans is the defining trait of robotic application if it is to mimic human cognitive traits. Speech recognition, instead of command line or GUI input is a minimal requirement. Conversely, data to speech capability is a must. While robots with human-like facial and body features can make interaction with humans easy, this is not necessary.

Some strides have enabled servo-assisted mechanical eyelids, eyebrows and some semblance of lips articulating the spoken word can be programmed to show facial expressions. Artificial emotion of a limited range can also be defined like surprise, sadness, elation that mimics those exhibited by C3PO in Star Wars and Pixar’s Wall-E.

Learning Abilities and Full Autonomy

There are now AI-based inference engines that can accumulate information and analyze their trends and patterns to make recommended solutions when interrogated. They are commonly used in computer and telecommunication help-desk functions. This facility can now be applied to robotic application to support full autonomy for robots to make decisions and actions within their prescribed task directive. In other words, once turned on, they can do their task with no human control unless there are override commands built into the program.

Locomotion

While not really necessary, we’ve all seen how the movies portray robots as mobile electro-mechanical machines that use either motorized wheels of feet-like parts to move around. There are already mobile robots in some high end hospitals that delivery medication to patients on motorized wheels, not on leg-like contraptions. Human-like feet is nice to have but robotic engineers will have to factor in balancing mechanisms which humans have in their ears so they don’t fall on unstable two legs.

Perhaps tri-pod like tentacles can provide better stability in this area without having to bother with such balancing mechanics. Motorized wheels on all fours remain the most viable option.

Social Implications of Near-Human like Robots.

This subject has been excellently explored in many science fictions novels and movies. The most recent was Spielberg’s A.T. or Artificial Intelligence. It basically asks how we should treat robots that behave and look like humans. Do we treat them as social being with rights to life or existence. Even the blockbuster I,Robot posits that same dilemma.

If robots start to exhibit human emotions and responses, how do we deal with them. Well, this is best left answered by moralists and technological psychologists with the end in view of protecting human life and its innate dignity more than anything. Suffice it to say that we are still quite a long way for robotic science to make robots a common street and household appliance, much less mistake them for humans. GP
