We seem to have a fascination with robots being more and more like humans. We are training them to imitate the way we walk, pick things up, and even gesture. But I think the thing most people aren’t realizing is how much better than humans robots will be (very soon).
The light bulb went on for me a few months back when a saw a video of a humanoid robot lying on the floor. It bent it’s knees completely backwards, placing it’s feet on either side of it’s hips and lifted itself to standing from close to it’s center of gravity. Then it walked backwards a few steps before rotating it’s body 180º to the direction it was walking.
I was again reminded of this recently when I saw a robotic dog going over rugged terrain, and when it reached level ground, instead of running it just started to roll on wheels. The wheels were locked into position when the terrain was rougher, and it made more sense to be a dog-like quadruped to maximize mobility.
There is no reason for a robot to have a knee with the same limited mobility as our knees. A hand might have more functionality with 3 fingers and a thumb, or 4 fingers and 2 opposable thumbs on either side of the fingers. Furthermore, this ‘updated’ hand can have the dexterity to pick something up using either side of it’s hand. It would be like if the hand had two palms, simply articulating finger digits to go the opposite way when it is practical. Beyond fully dexterous hands, we can start to use our imagination: heads that rotate to any direction, a third arm, the ability to run on all-fours, incredible jumping ability, moving faster, being stronger, and viewing everything with 360º cameras that have the ability to magnify an object far beyond human eyesight capabilities. All the while processing more information than we can hold in our brains at once.
Robot dogs on wheels are just the first step in creating robots that don’t just replicate the mobility and agility of living things, but actually far exceed any currently abilities that we can think of. Limitations to these robots of the near future are only going to be a result of our lack of imagination… human imaginations, because we can’t even know what an AI will think of in 20-30 years. We don’t need to worry about human-like robots, but we really do need to worry about robots that will be capable of things we currently think are impossible… And I think we’ll start to see these in the very near future. The question is, will they help humanity or will they be used in nefarious ways? Are we going to see gun wielding robot dogs or robots performing precision surgery and saving lives? I think both, but hopefully we’ll see more of these amazing robots helping humanity be more human.
