After Losing His Fingers, Engineer Built His Own Steampunk Mechanical Prosthetic HandAfter a workshop accident where he smashed his hand, Ian Davis suffered a blood infection that ultimately led to amputations of four fingers on his left hand. To make matters worse, Davis learned that his insurance would have covered the cost of a prosthetic hand if he had lost his entire left hand - not just the four fingers because "fingers are not medically necessary."Being a mechanical engineer, Davis decided to build himself a steampunk prosthetic hand - one that is better than a medical prosthetic hand, and at a fraction of the cost.In this YouTube video, Davis managed to enable the splay function on his mechanical prosthetic hand.

This Cockroach Robot Can't be SquashedOh great! As if the upcoming robot apocalypse isn't scary enough, engineers have now created a cockroach-inspired robot that can't be squashed."Most of the robots at this particular small scale are very fragile," noted professor of mechanical engineering Liwei Lin of UC Berkeley, "If you step on them, you pretty much destroy the robot ... We found that if we put weight on our [cockroach] robot, it still more or less functions."Made from a piezoelectric material, Lin's robot weighs about 20 to 65 milligrams, but can withstand being stepped on by a human - that's over one million times its own weight. It can move at speed of about 20 body lengths per second (nearing the speed of a scurrying cockroach) and carry loads up to 6 times its own weight.#robot #cockroach #MechanicalEngineering #LiweiLin #piezoelectric #UCBerkeley

Hubless Bicycle: No Wheel Spokes, No Problem!Ever seen a bicycle without any spokes on its wheels? Well, now you have: The Q engineer created a hubless bicycle out of a "fat bike, bearings, some metal and time" (not to mention machining skills and some crazy imaginations!)#bicycle #wheel #TheQ #FatBike #mechanicalengineeringView the full video clip below:

Active Ball Joint Mechanism (ABENICS) Spherical GearKazuki Abe and colleagues from Yamagata University and Tohoku University in Japan created a mind-bending gear shaped like a sphere that drives three rotational degrees of freedom without slippage.The active ball joint mechanism (ABENICS) uses two different gears, a cross spherical gear and a monopole gear on a quadrature tooth structure of the spherical gear.Published in IEEE Transactions on Robotics, the researchers noted that ABENICS can transmit both high torque and reliable positioning without an orientation sensor, and can be used in robot joints.Fascinating to watch!#gear #balljoint #mechanicalengineering #robot #joint
