Winners of MAKE Volume 27 Robot Contest

Chopsticks, Winner of the MAKE Volume 27 Robot Contest

Here at headquarters, we just wrapped up the newest issue of MAKE, Volume 27, the Robot issue. Look for it on newsstands on July 26th. While we were working on the issue, we were curious to see what kinds of bots our community members were making and thought it would be fun to host a little contest. The premise of the contest was simple: we were looking for bots with lots of character. To enter, folks contributed their build photos and text into Make: Projects, along with a video of the bot in action. Entries were judged by the editorial staff of MAKE based on the following criteria: (a) Entertainment Value: 50%; (b) Quality of Written Documentation: 25%; and (c) Quality of Documentation Photography/Video: 25%. We got some great entries, and ran images and links to the winners in MAKE Volume 27. It was a tough call, but we tallied up one Top Bot and 3 runners up. And the winners are…

TOP BOT:

Chopsticks the Spider Robot by Russell Cameron won us over with his big eyes, the way he walks, his awesome legs made of chopsticks and polymorph plastic, and Russell’s fabulous project documentation and videos.

RUNNERS UP:

We loved Robobrrd by RobotGrrl, with its nature-inspired design, colorful appearance, eraser lashes, and RobotGrrl’s great project documentation, complete with hand-drawn sketches.


Belvedere the Butler Robot by Andy Wolff was by far the most utilitarian bot, with his ability to deliver food, play music, dance, and tell jokes. Who doesn’t need a butler bot?


And lastly, the Robot Drummer by Tim Laursen was certainly entertaining (and bizarre). We’re not sure we’ve ever seen that many colors incorporated into a bot before.

Thanks to everyone who entered! We loved seeing what you make.

Quick ‘n Dirty Belt Sander Holder

The ever-industrious Craig Smith sent us a message with some photos of a jig he built to hold his belt sander in place for hands-free sanding. He writes:

I love my hand held belt sander, I use it all the time. But occasionally I need a stationary belt sander to sand small items, or to slide material on a table into the belt, to keep a perfect 90 degree angle. So I made a quick rig that tightly holds the belt sander on a tabletop. The lag screws are in pre-drilled holes that are precisely positioned so the sander, when pushed down within them, is snug & secure. If I need two hands on my material, the sander does have a locking trigger. For years I used this rig before I realized that the motor fan draws air in on the other side to cool it and blow dust into the bag. (oops) So I recently added vent holes and an air channel to the underside, so the sander has proper air flow.

New Alloy Becomes Magnetic on Heating

This video is short, and really pretty boring if you don’t know what’s going on. Shown is a chunk of new alloy (Ni45Co5Mn40Sn10) that undergoes a phase change, at about 125C, from a nonmagnetic material to one that is strongly magnetic. If you bias the system with an additional, permanent magnet, heating the system past the transition temperature produces an electric current in a nearby coil, thereby converting heat to electricity. The alloy was produced by Vijay Srivastava, Yintao Song, Kanwal Bhatti, and R. D. James at the University of Minnesota and recently published in Advanced Energy Materials. [via adafruit]

 

Help RadioShack, Win $150 in Maker Shed Booty

RadioShack is looking to better understand the needs of makers/DIY hobbyists. As part of that effort, they’ve asked if we would run a brief survey here on MAKE. They’d like to hear from you. It’s a brief survey, which will take about five minutes of your time, and as an incentive, we’ll be be giving away a $150 Maker Shed Gift Certificate, at random, to one respondent.

Update: The survey is now closed. Thanks so much to all those who chimed in. We’ll announce soon who gets the $150 Maker Shed credit. But DO feel free to continue the discussion about RS. I know they’re reading our comments, so it’s a great way to communicate your thoughts to them, your frustrations, and especially, your desires for what RadioShack could be.

Here’s the survey.

Verbalizer: Arduino Dev Board for Google Voice

Want to mix a bit of physical computing into your Google Voice Search? Breakfast NY has built an open source, Arduino-compatible dev board to do just that.

With Google announcing the launch of Voice Search for desktop, we couldn’t help thinking that there was even more fun to be had with talking to a computer. So, we went ahead and built an open source dev board to inspire people to build their own useful and wacky contraptions to take Voice Search to another level.

To show off the plethora of things that can be created with the Verbalizer, we invited some electronics newbies out to our first ever Make ‘n Break workshop to share some toys we built with the Verbalizer, as well as to let them have a play.
WANT ONE?!?
We’re giving a limited number of these bad boys away to people that are going to make some magic with them. Fill out the form below if you’re interested. We’ll drop a note to all of the lucky winners by July 1st.

Make: Live 6/22/11 — Photo and Video (video)


Make: Live episode 11 is all about photography and video. We take you on a behind-the-scenes tour and show how we put together Make: Live.

Matt Griffin from MakerBot shows us how they make timelapse movies of 3D printers doing their thing. Catch up on video and notes from the show here.

Subscribe to the MAKE Podcast in iTunes, download Make: Live episode 11 in its entirety (m4v or Vimeo). Also check out the chat room transcript!


Show notes:

Some time lapse tips and tricks from Matt Griffin:

  • You need something that is fixed or moves slowly to “gel” the time lapse
  • Be careful of auto-exposure and auto-focus, as these kill illusion.
  • Sell realism by simulating camera moves — s-curves and ease in/ease out help give the viewer a cinematic handling feel while direct lines feel kinda mechanical (security cameras)
  • Typically folks add music after the time lapse — but if you pick music you like, you can make adjustments to the time lapse to connect it to (or work against) the music.
  • Shoot a big enough image to give you room for reframing — but make sure the resolution for a tighter shot looks good enough for your needs.
  • Many time lapse/stop motion/intervalometer type tools can be hacked to be queued by something other than time. If you are recording something that changes over time, you can create a tool to trigger the shots that are interesting (motion sensing, tracking, sound sensing etc.)
  • Once you are done shooting, it is like you have a strip of film. You can use any number of batch file renaming or image processing tools to change parts or all of your sequence well before encoding it as video.
  • you can “thin” out your time lapse to have only images doing what you want, and then use a batch file renaming tool to create a new consecutively numbered sequence of images.

Want to show us your project? Upload a video or photos and send a link to live@makezine.com.

Make: Live 12: Robots
Wednesday July 13th, 9pm ET/6pm PT

Robot Butler Serves Drinks Autonomously


This robot was designed, manufactured and programmed for a design competition (as part of the curriculum) held amongst first year Mechanical Engineering students at Delft university of Technology.

The goal was to create a robot that could perform a delivery as quickly as possible, while also keeping as much as possible of the delivery on board.

Our design didn’t win an award for fast delivery or keeping most water on board, but we did win the Delft Science Centre award because our design has the most potential for actual usage. Out of 50 teams competing, we built the only robot that could steer and navigate its route autonomously.

50 teams with 8 members each took part in the competition, resulting in a wide variety of designs. There weren’t many strict guidelines, except for some dimension limits. One major constraint was that forward motion could only be done with a supplied cordless power drill.

Designing and manufacturing was done in approximately five months. All of the components were carefully designed in SolidWorks (A 3D CAD tool) and we manufactured each part later on.

Love the details on this. Cooly, the drink tray tilts forward to allow the robot to accelerate without spilling drinks. Also, the keen eye can see a Lego Mindstorms compass sensor mounted on the back. [Via The NXT Step]
