The Automated Doggy Door feeds your dog, replenishes his water and lets him out into the backyard. Markus Lutz and his team of students at Colorado State University created this complex system that reads your dog’s collar and opens the doggy door. The door can also be opened by a step switch right in front of the door, so Fido can let himself out (and back in) at will. It closes automatically after 10 sec. The gadget also fills the dog’s food bowl while playing a recording of your voice calling Fido to dinner. The gadget comes with a water bowl mechanism that includes a level sensor and float for automatic water replenishment, so Fido never goes thirsty.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
