But before he had his Master’s in Aerospace Engineering and Rotorcraft, he got started the same way many of us did, by playing around with DIY projects. He’s currently an aerospace engineer at Johns Hopkins Applied Physics Laboratory, where he works on the unique challenges faced by autonomous flying vehicles such as the detection and avoidance of mid-air collisions, as well as the development of vertical take-off and landing (VTOL) systems. Being on firm ground ground gives the robot a clear understanding of its position and orientation, which greatly simplifies tasks such as avoiding collisions or interacting with nearby objects.īut what happens when that reference point goes away? How does a robot navigate when it’s flying through open space or hovering in mid-air? That’s just one of the problems that fascinates Nick Rehm, who stopped by to host this week’s Aerial Robotics Hack Chat to talk about his passion for flying robots. While these two environments are about as different as can be, the basic “rules” are pretty much the same. When we think of robotics, the first thing that usually comes to mind for many of us is some sort of industrial arm that’s bolted to the floor, or perhaps a semi-autonomous rover trudging its way across the dusty Martian landscape. If time zones have you tied up, we have a handy time zone converter.įeatured image: Low-cost, open-source XYZ nanopositioner for high-precision analytical applications, CC-BY-4.0Ĭontinue reading “Low-Cost Nanopositioning Hack Chat” → Posted in Hackaday Columns, Slider Tagged Hack Chat This week we’ll be sitting down on Wednesday, June 15 at 12:00 PM Pacific time.
Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. He’ll stop by the Hack Chat to discuss how we can build nanopositioning and sensing into our projects, and to start exploring the world we can’t even see. Using old DVD players or off-the-shelf linear slides, he’s able to achieve nanoscale movement and sensing for a variety of purposes. To help us sort through the realities of nano-scale positioning, En-Te Hwu, a professor at the Technical University of Denmark who works on micromachines for intelligent drug delivery, has spun up some really interesting low-cost nanopositioning systems. Being able to move things at nanometer resolutions isn’t easy, but it’s not impossible, and it can even be accomplished on a DIYer’s budget - if you know what you’re doing. The world has gotten much, much smaller lately, and operating on that scale requires thinking about motion in a different way than we’ve been used to. Where once the height of technology was something like a water-powered mill, whose smallest parts were the size of a human hand and tolerances were measured in inches, today we routinely build machines by etching silicon chips with features measured in nanometers, look inside the smallest of cells and manipulate their innards, and use microscopes that can visualize materials at the atomic level.
That’s not a moral or ethical proclamation, but rather an observation about the scale of technology. It may sound like a provocative statement to make, but technology has been on a downward trend for a long time. Join us on Wednesday, June 15 at noon Pacific for the Low-Cost Nanopositioning Hack Chat with En-Te Hwu!
