GTOlover, mimic doesn't mean "reproduce exactly," at least not in robotics. I was a little surprised that a pinky--i.e., a short final finger--didn't make the grade, but only a little. One of the main goals to be traded off in most of these projects was cost, so five digits weren't usually necessary. You don't need a pinky--as per definition given above--to throw a football, although a fifth finger is helpful. To throw it like a pro player? Yeah, it's probably needed. But that's not what these bots are built for. Plus, the functioning of only four fingers can be vastly improved over the human grasping system, as mentioned in a few of the slide captions.
Given that the post is "Robotic Hands Mimic Humans" and humans have pinkies, it would be good to include this appendage. I am not sure you would call the pinkie useless as it adds an additional control, like throwing a football. Yes it can be done without a pinky, but is it as precise?
Seems a lot of good designs already exist in nature and we just need to copy them to mimic them.
Isn't that true, Chuck? Making robotic movements fluid is still something that engineers need to work on. I saw this recent story that was quite interesting...about a robotic arm that creates delicate art: http://www.fastcodesign.com/1671977/watch-delicate-art-made-with-a-massive-robotic-arm#1
Last week, I visited Worcester Polytechnic Institute's robotics department. WPI was the firs university in the nation to offer a BS degree in robotics. See my first of two reports in Students Design Robots.
This report looks at the over all program. Tomorrow's will look at a specific project.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
