We know that robots today can accomplish a multitude of tasks like assembling parts, picking farm produce, doing a quick scan of surroundings, and greeting people at malls. But can they learn by themselves like primates? Scientists argue that since robotics is slowly approaching its peak stage, it will be hugely beneficial and exciting if the robots could learn on their own, from interactions with the physical and social environment. While AI and machine learning are doing their part in augmenting robotics, implementation is not simple as most robots have a limited learning capacity. Through reinforcement learning (RL) is purported to be the simplest way to train robots, much work needs to be done.
