Here's a blimp with its own ideas of flight. Nick Wagner and
his fellow classmates at Colorado
designed their infraLED Zeppelin to maneuver in two modes. The first is remote
control mode where a transmitter sends directional commands (forward, back,
left and right) to the blimp and the blimp responds accordingly. The second
mode lets the blimp chart its own course to a predetermined destination. In the
autonomous mode, the blimp flies to an infrared (IR) beacon. IR transmitters on
the blimp receive a signal from the beacon, and the transmitter facing the beacon
receives the most pulses. The blimp then goes in that direction.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
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.
