There are unsung heroes out there who have saved countless lives. Like a true superhero, their only response to those saved is a simple "I'm only doing my job."
They are the men and women of the Joint Robotics Repair Detachment (JRRD), and they keep the US military's robot armada up and running. These bots are almost exclusively tasked with handling IEDs, improvised explosive devices, and other traps and explosives.
The JRRD handles robots ranging from the single digit pound range to several tons. Repairs are not always for the IED-damaged robots. Normal wear-and-tear finds that the bots need replacement treads or wheels, cameras, motors, and faulty electronics. More extreme cases have the repair technicians replacing major portions of the bots, such as arms and other mutilated components.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
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.
