Here's a robotic hand that teaches sign language, including the international sign for “rock on.” J.D. Ritchey and his fellow mechanical engineering colleagues (Tim Campbell, Nick Haub and Brian Taylor) from Colorado State University created an acrylic hand to assist in teaching sign language. The Sign Language Emulating Robotic Assistant features all the digits of a human hand. Punch in a specific letter and the hand forms the sign language position. The students take sign language a bit further than standard letters. Punch in “rock on” and the hand forms the rock concert sign with the index finger and the pinky showing the classic fan symbol for keep on rocking.
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
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.
