Procrastineering - Project blog for Johnny Chung Lee: Robots: Cute and Less Cute
"When it comes to robotics, I typically jump to the technical aspect of planning, kinematics, & tracking. It can get nitty gritty really fast. But, it's great to see what just a little bit of artistic creativity can do when applied to even the most modest of robots. I hardly ever see anything quite this "cute" come out of the robotics research community:

Okay well, there's KeepOn by Hideki Kozima & Marek Michalowski which is pretty good.

At the complete other end of the "cute" spectrum is this recent video from Boston Dynamics…

Boston Dynamics continues to push hydraulic actuators farther than I think anybody thought they could. But, why does it have run like some kind of giant insect rather than an actual cheetah? Surely, staggering the foot falls would provide mechanical advantages I am not knowledgeable enough to articulate. Developing a robot capable of matching the maneuvering performance & speed of a cheetah would be quite remarkable."

Mustafa's Space Drive: An Egyptian Student's Quantum Physics Invention | Fast Company
"Aisha Mustafa, a 19-year-old Egyptian physics student, patented a new type of propulsion system for spacecraft that uses cutting edge quantum physics instead of thrusters…

Mustafa invented a way of tapping this quantum effect via what's known as the dynamic Casimir effect. This uses a "moving mirror" cavity, where two very reflective very flat plates are held close together, and then moved slightly to interact with the quantum particle sea. It's horribly technical, but the end result is that Mustafa's use of shaped silicon plates similar to those used in solar power cells results in a net force being delivered. A force, of course, means a push or a pull and in space this equates to a drive or engine.

In terms of space propulsion, this is amazing…

if you want proof that the tiniest of pushes can propel a spacecraft, check this out: Two Pioneer space probes, launched in the 1970s, are the farthest manmade objects from Earth...but they're not as far away as they should be…"

Flexible robotic fin does away with drag - tech - 29 February 2008 - New Scientist Tech
"A robotic fin that mimics the energy-efficient manoeuvres of an agile fish's pectoral fins has been developed by US researchers. Working out how to use multiple versions in conjunction could allow robot submarines to hover and turn on a dime as natural s
