I have seen how difficult it is for scientist to make a robot walk on two feet, it seems that walking on four legs is a much more simple solution. The advantage to walking on feet instead of rolling on wheels is that you can cover more difficult terrain. This robot dog seems to show a lot of promise in terms of dominating various terrain. With its quick reaction time, it really seems likes it’s alive. That part kind of scares me because all I can think of is the movie Terminator, where in the future our high tech machines turn against us.
