Can a Machine think? I think, at least at the present, technology hasn't quite gotten there yet, depending on your definition of "think." If the definition were considered to be weighing information and making decisions, I think that these robots are able to think, in their own little way. They can sense other things and people, and decide what to do based on the circumstances. I have not previously had any experience with coding or building robots, but I was shocked at the amount of detail can be put into one "decision" by the robot. Similar to humans, the robot can weigh many different aspects of the decision and make the best decision based on what is prioritized. 

But, I think the real definition of "think" is a lot more nuanced, and not something that AI robots have been able to achieve yet. To me, the "thinking" ability lies not in the ability to make decisions, but the ability to be able to determine, on its, own, the criteria for those decisions. Humans are complex animals with complex brains, and all of the aspects of this brain are connected in a variety of ways. The aspect of humans that is still lacking from even the best robots and AIs is common sense and understanding very nuanced conversation. Even the best AIs can still have trouble passing the Turing Test because sometimes their answers are quite literal and it is clear that the conversational jokes and nuances are not understood. To me, this is necessary for thinking. 

Another aspect of thinking is creativity. In terms of our robot, no creativity was available to surprise to opponent. If the robot was able to think like a human, he could come up with creative ways to attack the opponent that might not be expected. In terms of AI in general, creativity is a hot topic. AI have been able to make paintings and music, which some believe shows the "creativity" of robots. But, in every-day life, creativity means much more than just the arts. Creative decisions allow us to solve problems in unconventional ways, and this type of thinking is still laking in AI.  

Machine learning is getting artificial intelligence closer and closer to this nuanced thinking, but at the moment, even the best AI can't really "think" yet.
