Autodesk Octo-Copter Testing

is originally published on

Between the Lines

As I mentioned in a recent post (Aerial Capture of 3D Geometry), I was hoping to attend a test flight of the remote controlled Octo-Copter that captured photos that were then used to automatically generate a 3D model using Autodesk 123D Catch. Last Thursday the weather and my schedule aligned and I joined Autodesk employee Gonzalo Martinez Director of Strategic Research in San Rafael California for test flight of the 8 bladed aerial copter. The eight rotor aircraft can operate 100% autonomous based on a programmed GPS route and patterns or if you are skilled you can run in manual pilot mode.

Here is the video from this test flight:
https://www.youtube.com/watch?v=rgZLUf1TMDA

The Octo-Copter can reach 3500 meters flying by First Person View (FPV) or 1000 meters distance if flying autonomous GPS in accordance with FAA rules for Unmanned Aerial Vehicles (UAV). The current payload can be up to 2 kg such as cameras sensors, and a fluffy puppy. OK there was no puppy onboard the copter, but as smooth and safe as the flight was we could have. If I weighed in under 2Kg, I would have happily climbed aboard for the flight.

During flight the Octo-Copter transmits a live video feed FPV back to a remote LCD screen or video display goggles. This allows the pilot to see what the Octo-Copter sees like a virtual onboard pilots eyes. I felt a little weird when wearing the goggles seeing the live video looking down from a few hundred meters zooming along like a bird. It was as if I had channeled my inner falcon for an out of body experience.

We had one person show up to the field we were flying from reporting that a couple people a few streets over had reported they saw a UFO or some secret police surveillance drone. We set this persons mind at ease and told him it was just a research project to capture 3D geometry of the Autodesk headquarters located across the field from us.

The possibilities for aerial 3D capture are wide from construction to historical preservation. Research is continuing on the Reality Capture whether on the ground and in the air.

I spent the last week in the San Francisco Bay area Autodesk offices. It is always great seeing colleagues of mine as well as the beautiful San Francisco Bay Area. Here is my quick visual story in pictures of this week captured with my mobile phone.

Nobody should ever miss an opportunity to visit Ritual Coffee Roasters in San Francisco for a great coffee and a crowd of tech heavyweights seated in the coffee shop.

Visited Hackerspace Noisebridge (http://www.noisebridge.net)
Read More: Hacker Spaces – Come Meet Your Makers

Several scenic ferry rides across the bay to get to the office. This has to be one of the best commutes ever with the scenery and being able talk with people without worrying about a car cutting you off on the congested freeway. I can never have enough middle fingers for the highway 101 commute.

The new span of the San Francisco Bay Bridge is coming along nicely.
http://baybridgeinfo.org/construction-cams

Looking out my fourth floor office window I notice I had a feathered stalker staring back at me. Apparently this seagull is known by a few Autodesk employees as “Jonathan” and sits in window ledges frequently.

See more of my images from the week:

In addition to some of the best restaurants in the world, San Francisco has high end catering trucks and unique food vendors.

On Wednesday I visited the crazy creative folks in the Instructables.com office to discuss some future projects as well as snoop around the office at their cool projects. I got to see the infamous Clap Off Bra and the 12 foot tall cardboard Trojan horse they used to try and enter the Autodesk building for the Christmas party. Check out the Trojan horse vide http://youtu.be/Hosmu-0ECBoheck out

You should check out Instructables.com to learn how to make projects varying from  electronics, food, robots, crafts and even more.

The SF vertical cityscape.

On Thursday I worked from the Autodesk San Rafael offices and met up with colleague Gonzalo Martinez to test the Autodesk Octo Copter. This is a kit built 8 rotor unmanned aerial vehicle drone. With this drone we are able to capture real-time video as well a capture high resolution images to create 3D models automatically using Autodesk 123D Catch. The drone can be flown manually or programmed for autonomous flight paths. Read More: Aerial Capture of 3D Geometry

One of the funniest things to occur during flight testing was a vehicle pulled up next to us. The guy wanted to know what was flying around as some people doing some construction work had thought it was either a UFO or some secret police spy drone.

Autodesk celebrated being on the Fortune Magazine’s list of top 100 companies to work for. Nice excuse to have cake!

More sights of the Bay from walking around it in the evenings in Larkspur to seeing the fog settled in the morning around downtown San Francisco.

Friday morning I visited artist Marco Cochrane at his studio on Treasure Island. Marco creates sculptures of art displayed around the world as well as at the famous Burning Man event. http://www.marcocochrane.com/

Finally later Friday out the view of my airline window I see a fine sight, I see home.

On This Day in 1982 – The Design Industry Changed

is originally published on

Between the Lines

Autodesk was created on this day January 30, 1982 and would bring Computer Aided Design (CAD) down from the expensive mainframe systems to the PC with a new product named AutoCAD. Since that time CAD has grown and branched out into other CAD specialty processes like Building Information Modeling (BIM) and Digital Prototyping. Autodesk also helped pioneer design visualization growing it from the DOS based 3D Studio in the early 80s to an entire business division of media and entertainment covering not only design visualization but gaming, movie special fx, and more.

Autodesk Flying founders
”Autodesk Founders. They didn’t walk on water, but they could fly pretty well.”

Here’s to the next 30+ years of Autodesk, Computer Aided Design, and Visualization – and the changes it will bring the world of design!

Hacker Spaces – Come Meet Your Makers

is originally published on

Between the Lines

This week I had the opportunity to visit the Noisebridge Hacker Space in San Francisco with an Autodesk colleague Gregory Miller and Alex Peake. Alex is on Kickstarter with a game project named Code Hero where you not only learn about pioneers and computer science heros such as Charles Babbage, Ada Lovelace, and Alan Turing but learn how to code in the process of the game. It is nice to see not another mind numbing zombie killing game, but one where you learn some programming languages such as JavaScript and Unity3D, and exercise your problem solving skills.

Don’t let the name “Hacker Space” scare you. A Hacker Space is not a group of people sitting around hacking into your online accounts, but a group of people young and old who work on projects from a wide array of things such as computers and electronics to building robots, lasers, rocketry, and wood working.

I love seeing Maker spaces where creativity and making things is the main purpose of people gathering in a common space. In this visit to Noisebridge I saw some young children about 10-12 printing some 3D plastic designs on some of the available MakerBot printers, a teenager writing a program that takes the electrical signals from a special head band to drive a terrain game engine, some high school students working on a robot for the FIRST Robotics competitions, some people sewing a project, another group working on some wood working, and several others all on a Sunday afternoon. What a cool and creative space to learn, build, and share with others.

Some members of Noisebridge also had a great sense of humor with their signs on everything everywhere!

There are Hacker Spaces all over the world and other Maker spaces like TechShop spreading to fill the needs of those that are not satisfied with just running down to the store to buy a alarm clock and instead get an open-source Arduino microcontroller circuit board and a bunch of LEDs and then begin to build and program their own alarm clock. Not only do they end up with a one of a kind alarm clock but the special knowledge after having built it themselves.  I would strongly urge you to look into a Hacker Space or other Maker related space as there are most likely groups in your town where you can participate and contribute building your own projects or mentoring others members.. Even if the maker movement is not for you, I bet you know someone that has an idea just dying to get out of their head and build it themselves.

Here are some online resources on spaces:
http://hackerspaces.org/wiki/Hackerspaces

I would also encourage you to attend MakerFaire as that is one mind blowing experience with tens of thousands of Makers gathered in one location to show of their creations.

Create a 3D Model of Your Head

is originally published on

Between the Lines

I wanted to show how anyone can create a 3D model of themselves or a person they know using a digital camera, free Autodesk software, and a 3D printer.

Here is an example of my two Autodesk colleagues Brian Mathews and Scott Sheppard as 3D printed miniature heads- about the size of Barbie doll heads. I could have printed the heads much larger, but that also increases the creepiness factor of carrying around a rather large plastic head of a coworker.

Here are Scott  & Brian with their mini 3D printed heads.

How I did it:

With the person holding very still and me walking around them, I took about 40 photos of their head. I then used the free Autodesk 123D Catch where you use photos to automatically generate a 3D model.  When I was satisfied with the results, I  exported an .OBJ file to use as the raw 3D model I wanted to use for 3D printed plastic heads.

Here are the screen captures from 123D Catch of the texture and wireframe mesh models of both Brian and Scott.

I then cleaned mesh model for 3D printing by opening the .OBJ file in the free Autodesk meshmixer. Meshmixer allowed me to fill and zipper holes, smooth areas, and reduce or refine the mesh areas as well as remove portions of the mesh. I can also paint with volume brushes to create more detail or even add other OBJ content to add say a pair of horns to a persons head just in case you intend to mount it on the wall. When I am done I export the file as .STL ready for printing.

Now using the .STL file I can print the head in ABS plastic on a 3D printer like a Makerbot or using an online 3D printing service like Shapeways.com. You could also import the .STL file into Autodesk 123D Make and slice up the model into layers which can create a pattern to construct a 3D model out of cardboard.

Scott’s head being printed on a MakerBot.

You can even import the .STL file Project Falcon to see how fluids would flow around your cranium using Computational Fluid Dynamics (CFD) analysis.

I hope you will give this fun experiment a try as it is not only fun but a real conversation starter when you have a recognizable coworkers head or your own on your desk, or in your pocket. Of course there are more practical objects you could capture and 3D print using the same methods such as statues, architecture, and even geology such as the mountain I 3D printed from a Autodesk 123D Catch created 3D model.

Shaan

Living in a World of Fluids

is originally published on

Between the Lines

Perhaps there is no better way to study fluid dynamics than by visiting your local water park. With its water slides, wave pools, water fountains and more, water parks are a seriously fun way to experience the study of fluids in motion.

Welcome to the world of fluid dynamics: the study of the motion of fluids, including both air and water! As with all things, energy is required to move objects through fluids and is lost when a fluid moves through an object—like water in a pipe or air through the ducts in a building. Major head losses occur in the friction forces between the pipe and the fluid, and minor head losses occur as the fluid travels through bends and valves.

One way to optimize designs is to eliminate sharp turns or widen your pipes. (Great for buildings, not so much for water parks.)

Cars are another everyday example of fluid dynamics at work. To improve aerodynamics and use less energy, you need to reduce the drag coefficient. For example, the Urbee case study has enclosed wheel wells and gentle curves in the front and back. These give it a streamlined shape that reduces its drag coefficient to about half that of normal cars.

Engineers can create energy-efficient designs that optimize fluid flow by making smarter choices on the forms, speeds and materials of their designs. Computational fluid dynamics (CFD) simulations can help you optimize your designs by helping you to better understand how your design will interact with fluids. You can experiment with CFD using the free technology preview Project Falcon on Autodesk Labs: http://labs.autodesk.com/utilities/falcon/
